Demerara Distillers Ltd – Part Two

This is part two of a series about Demerara Distillers Ltd. In part one I covered the history of Guyana’s rum industry, how Demerara Distillers came to be, and their operations today. Much of it is necessary background for what follows. There’s lots to cover here, so I won’t be reviewing material given in part one. I highly suggest you read that first.


It’s a beautifully sunny but humid morning as I wait outside
Georgetown’s Pegasus hotel to meet my driver from Demerara Distillers Ltd, henceforth
referred to as DDL. As our car skirts along the banks of the Demerara river I
soak up the air-conditioning, knowing that after arriving at the Diamond distillery
on the city’s outskirts, the hot Guyana air will be further supercharged by the
steam flowing through the distillery’s historic stills.

DDL’s complex at Diamond, which includes the distillery, aging warehouses, bottling plant, administrative offices and more, is massive. Back in the 1700s, it was one of many sugar estates established along the banks of the Demerara river. Today, there’s not a sugar cane plant to be found anywhere on the grounds.

Entrance gate at Diamond Distillery, Guyana

After passing through the guard gate and pulling up the distillery complex, I’m greeted by the distillery production manager, Darryl Manichand. Looking to be in his early 30s at most, he’s not the grizzled veteran you’d expect. However, his appearance belies a very extensive knowledge of distillery operations. He was recruited by DDL at a relatively young age and extensively trained on any number of different rum production roles. It’s a pattern I noticed at DDL. Nearly everybody I met was quite knowledgeable across many disciplines, not just their current role.

While cars speed by on the freeway running past the
distillery, Darryl and I first establish what I hope to see. In brief: EVERYTHING!

For a distillery so strongly associated with centuries of rum
production and its historic stills, the distillery complex is surprisingly
modern looking. If it weren’t for two enormous column stills towering nearby,
you might not guess rum is made here.

Preliminaries dealt with, Darryl hands me a hard hat and off
we go!

Water and Energy

Without large amounts of water and energy, a distillery can’t
make rum. They’re the essential circulatory systems of any distillery, enabling
it to turn agricultural material such as molasses, grapes, or grains into delicious
distilled spirits.

Being close to the Demerara river, Diamond has plenty of
groundwater below, extracted via three wells drilled 500 feet down. Constant
testing ensures the distillery doesn’t over extract the water table and the
quality of raw water confirms to World Health Organization standards before
further purification process and use.

As for energy, the distillery once powered its boilers
entirely with heavy fuel oil. In the past decade DDL started harvesting biogas
produced across the highway by mixing the distillery’s effluent with cow
manure. This was funded in part by a European Union grant and facilitated by
WIRSPA. Approximately 35 to 55 percent of the distillery’s energy needs for the
boilers are now met via biogas, with the remaining supplied by heavy fuel oil.

Molasses

Diamond is capable of making 20 million liters of pure alcohol
(LPA) per year, making it among the largest Caribbean distilleries today.
Naturally, it goes through an extraordinary amount of molasses – between 200
and 220 tons every day. Three enormous molasses storage tanks hold 1000 metric
tons at the ready.

In prior years, Guyana’s GuySuCo made enough molasses to fully supply Diamond as well as export to other rum-making countries. More recently, local molasses has only fulfilled about eighty percent of DDL’s needs, so the remainder is imported from elsewhere. However, efforts are underway to work with local sugar growers to get DDL’s percentage of local molasses back up to where it was previously. To achieve this, the sugar industry will need to focus on higher grade molasses, with a corresponding reduction in sugar extracted for sale. Put another way, the sugar content in molasses is more valuable for making rum than as table sugar.

Fermentation

Fermentation starts by propagating an active, dry yeast for around 18 hours in a set of propagation tanks. The contents of two such tanks, representing about 10 percent by volume, goes into one fermenting tank, along with molasses and water, of course.

Yeast propagation, Diamond Distillery, Guyana

Diamond has thirteen fermenters – eight closed and five open tanks which are situated close to the stillhouse. The open fermenters are so large that they’re surrounded by an elevated walkway made of open metal grating to gain access from above — try not to look down! From the walkway I crane my neck over the edge of a stainless-steel tank to see a firehouse of molasses slowly filling it. Looking around, I also catch a fleeting glimpse into the adjoining stillhouse, but that will have to wait.

The distillation term “dead wash” refers to the end result
of fermentation. I was quite surprised to learn that nearly all of Diamond’s
stills use the same wash profile. That is to say, the wash used for the Port
Mourant still is the same used for the Enmore, Versailles, and Diamond Coffey
stills. No special ingredients, extra-long ferments, or anything like that.
(We’ll geek out on the stills later.)

Open fermentation, Diamond Distillery, Guyana

Diamond’s typical fermentation cycle lasts for 24 to 30
hours. The five open-air fermenting tanks are exposed to additional airborne
yeasts historically found near sugar cane fields, so have a higher final congener
count at the end of fermentation. As for the eight closed fermenters, special
equipment collects the carbon dioxide fermentation byproduct for other uses
like beverage carbonation. DDL is the Pepsi franchisee in Guyana since 1993, so
they can use the carbon dioxide themselves.

The final wash for distillation is prepared by combining
both open and closed fermentations. In total, Diamond’s fermentation equipment supports
creating up to 55,000 liters of pure alcohol (LPA) per day. It’s no coincidence
that the fermentation capacity is matched to DDL’s biggest still.

Closed fermenters, Diamond Distillery, Guyana

The daily total capacity of all Diamond’s stills far exceeds
the amount of wash that can be made in a day, so only a subset of the stills
run at any time. Careful scheduling of what stills will be operated on a given
day are calculated based on current demands and future estimates of what types
of rum will be needed to blend specific products like El Dorado 15 year. These
estimates may extend fifteen years or more into the future!

Earlier, I mentioned that with two exceptions, all stills
use the same wash profile, i.e. a 24-30 hour fermentation in open and closed
fermenters. One of the exceptions regards the Savalle still. Distillation with
the Savalle starts with the same wash profile. However, during distillation,
low wines coming from the still are blended into the incoming wash that’s fed
to the still. The net effect is that the low wines are continuously redistilled.
We’ll touch on the second exception a bit later.

Distillation

After much anticipation on my part, Darryl and I enter the stillhouse
via the same elevated walkway surrounding the fermenters. It appears that the
original stillhouse was significantly expanded to accommodate all the stills
brought from Uitvlugt circa 2000.  All of
Diamond’s stills, save the two largest, are found within the crowded, noisy confines
of the stillhouse. It’s cozy enough that from a particular vantage point you
can likely see every still within – or at least part of each.

The figure above provides a general idea of where each of the Diamond distillery’s still are in relationship to each other. Be warned: It’s highly simplified, and not to scale.  

Diamond Coffey Stills

Original Coffey stills, Diamond Distillery, Guyana

Our first stop is the two Diamond Coffey stills, helpfully labeled
#1 and #2 on attached signs. Each has two columns, i.e. the traditional Coffey analyzer
and rectifier setup. The wash first enters the top of the analyzer, where the
alcohol is “stripped” from the water. The enriched alcohol them fed into the
base of the rectifier, where it rises through a series of plates, with the
final output collected near the top.

When DDL formed, these Coffey stills were already at Diamond
since the 1950’s. To my knowledge they weren’t installed somewhere else first.
They both make the same marque:
SVW, which a medium bodied spirit, one of the 24 or so marques that Sharon
Sue-Hang
, DDL’s Master Blender, blends to make different expressions.

In front of Coffey #1 and #2 are their respective spirit “test
cases”. Resembling something mildly steampunk, several large, capped glass cylinders
sit atop black metal cabinets. Warm distillate, fresh from the still, flows
through the cylinders, allowing its strength to be assessed by what resembles a
large glass thermometer to the untrained eye, but is actually a hydrometer
bulb.

Scale from plates of the Coffey #1 still, Diamond Distillery, Guyana

Darryl reaches down and plucks something from the metal
grating. In my hand it resembles a small piece of rock, roughly the size of two
stacked nickels.  Rather than concrete however,
it’s scale that has formed on the plates within the nearby still. Darryl
explains that there’s so much ash, limestone, and minerals within the local
molasses that even after initial processing to remove them, the remaining
solids still form a rock-hard cake on the still plates. This reduces still
efficiency and reduces copper contact. Thus, the operators shut down the still for
cleaning every few weeks. A crew removes each plate, chisels out all the hard
cake, then puts the plate back. It’s a slow, laborious process. The newer
column stills (MPRS and Coffey #3) operates under vacuum conditions at a lower
temperature, so less of this cake forms. Cleaning is easier and doesn’t need to
occur so often.

Tri-Canada Still

Tri-Canada still, Diamond Distillery, Guyana

Behind the Diamond Coffey stills is less well-known still
known as the Tri-Canada. It’s much more modern column still, and was installed
around 1980 using parts from John Dore and Tri-Canada Industries. These days it’s primarily used to make neutral alcohol for spirit
drinks, although newer stills have essentially taken over the Tri-Canada’s
role.

French Savalle Stills

Savalle stills, Diamond Distillery, Guyana
Savalle Still test cases, Diamond Distillery, Guyana

To the left of the twin Coffey stills are a pair of Savalle
stills. These are somewhat similar to a Coffey still, but with twice as many columns,
i.e., four columns. Originally, the French Savalle Stills were installed at the
Uitvlugt Distillery circa 1921 but now settled at Diamond Distillery since 2000.

The configuration of this four-column setup is highly
flexible, allowing the creation of different styles of distillates, ranging
from light to medium spirits. This still makes nine of Diamond’s 24 different marques.
Like the Coffey stills, the Savalle still also need to be regularly stopped for
plate cleaning and other maintenance.

Port Mourant Still

Port Mourant Still, then the Versailles still, then the Diamond High Ester still

Just past the Savalle still, a set of steps takes you down to a lower-level elevated walkway. Coming from the direction we did; I didn’t notice the Port Mourant still until I was practically standing over it. My jaw dropped when I saw it in the flesh, immediately recognizable from pictures, but also different than I expected. It’s very large, L-shaped, and wedged between walkways and metal piping, making it impossible to capture a good image of it in its entirety. As such, watching the video above is highly suggested.

The Port Mourant is arguably the most famous rum still anywhere.
Made mostly of greenheart wood, the rum it makes has a very heavy, oily, “green
plant” note that’s immediately identifiable, even in a blend of rums. The
unique Port Mourant flavor profile has become synonymous with British Navy rum
and in brands like Pusser’s and Lambs Navy that emulate it.

The Port Mourant still is technically considered a vat still. It consists of two very large, squat covered wooden vats, one bigger than the other.

Both vats have an enormous black swan necks rising from the covered top. The larger vat’s neck plunges into the top of the second vat. The smaller vat’s swan neck ends in a cylindrical retort, which is essentially a crude still heated by the incoming hot vapor. Rising from the retort is a rectifier cannister – cool water runs through the rectifier to create reflux as the distillate vapor migrates to the final condenser coil where it turns back to liquid.

Foreground: Rectifier column, Port Mourant double wooden pot still. Behind it: the two vats (painted red).

The Port Mourant estate, where the vats are claimed to have come
from, was established in 1732. However, the still’s current configuration with
the retort and rectifier was likely established significantly after 1732.

Luckily for me, the Port Mourant was running during my visit.
It’s easy to tell because the tops of both vats are under several inches of steaming
water. The water helps keep the wood on the top from drying out and warping. There’s
also steam emerging from where parts of the swan necks join together. It’s
undeniably very Old School.

While the Port Mourant still is called a “double wooden pot
still”, it’s not technically a double retort pot still, like found in Jamaica, Barbados,
or St. Lucia.

In a double retort still, prior to the distillation the
first retort is charged with low wines and the second retort with high wines. The
heated distillate moves from the pot into the first retort (low wines), on to
the second retort (high wines), and finally to the condenser. All of the heat
required for distillation is applied to the wash in the pot.

In contrast, the Port Mourant still is set up with wash in
both vats. Steam coils inside the base of each vat heat the wash. The vapor
from the first vat flows through the swan neck into the wash within the second
vat. The vapor from the second vat then flows via its swan neck into the retort,
up the rectifier, and so on.

If you’re hopelessly confused how this works (I was!), think
of the smaller vat as the first retort in a double retort still, although it’s
charged with wash rather than low wines. It’s a most unusual arrangement that
I’ve yet to see anywhere else.

Rum comes off the still in the 84-87 percent range. Interestingly,
for such a heavy rum, the ethyl acetate level of Port Mourant distillate is
only in the 20-50 gr/hL AA level, which is significantly less than a “funky”
Jamaican rum. Most of the Port Mourant flavors come from other congeners
besides esters!

French Versailles Still

Versailles wooden vat still, Diamond Distillery, Guyana

Next to the Port Mourant still, separated from it by the elevated walkway, is the Versailles still. It’s a classic Demerara vat still, and is also known as the single wooden pot still. Built in the 1890s, the Versailles still is very similar to the Port Mourant still, except there’s no second vat in the liquid/vapor pipeline.

The vapor from the Versailles pot flows into a retort and rectifier similar to the Port Mourant. In that regard, it’s a true single retort pot still. Rum comes off the Versailles still at around 84-86 percent ABV, about the same as the Port Mourant. In terms of the congener profile, it is roughly 60 percent to that of the double wooden (Port Mourant) pot still. If you desire a pot still rum with less “kick” in flavour, the Versailles is ideal.

Every so often, both the Port Mourant and Versailles undergo
maintenance to replace a few wooden planks comprising the side of the vat. Replacing
all the planks at once would change the still’s flavor profile too much.
However, in 2006 the Versailles still was in such bad shape that the entire vat
was rebuilt.

Diamond High Ester Still

Diamond High Ester still, Diamond Distillery, Guyana

Tucked between the Versailles and Savalle still is a very intriguing
still, unknown even to most Demerara rum geeks. The DHE (“Diamond High Ester”)
still is a relatively small John Dore double retort pot still, the only one of
its kind at Diamond.

According to Darryl, it’s from the 1950s and makes rums at
up to 70,000 ppm of ethyl acetate. That’s the same as 7,000 g/hL AA, which are
the units used for Jamaican rum ester levels. The wash for this still is the
second exception to the usual fermentation scheme at Diamond. The DHE wash is
made well away from the main fermentation area adjoining the still house. The DHE
wash ferments for several months and includes local fruits, similar to fermentation
for high ester Jamaican rum. The distillation process uses slow boiling and
high reflux within the DHE still to retain and extract the high concentration
of ethyl acetate formed during the “funky fermentation” process.

Tucked away at ground level, almost out of sight and near
the DHE still, is a very large blue bulb with a tall metal neck. It’s a batch still,
used to make the gin that DDL makes, branded as Lord’s Robert Gin.

Enmore/EHP Still

Enmore/EHP still, Diamond Distillery, Guyana

At the far end of the still house looms the twin columns of
the Enmore wooden Coffey still. Enmore is the estate/distillery where it originally
resided, and EHP are the initials of Edward Henry Porter, the onetime owner of
the Enmore estate. Thus, the still and associated marque is also known as
“EHP”.

Both columns are made from the same greenheart wood used for
the wooden vat stills. Dozens of large wooden rectangular planks are arranged
to form a pair of square columns at least twenty feet high. Each plank is
painted red, although much of the paint has fallen away. Metal rods with bolted
ends stretch across and through the planks, hold the whole contraption
together. Inside are the plates like you’d find in any other Coffey still,
except that they’re square, not round. The analyzer column has wooden plates while
the rectifier has copper plates.

Enmore/EHP still, Diamond Distillery, Guyana

The Enmore still was built around 1880 and is the last
remaining wooden Coffey anywhere. As with the vat stills, planks in the Enmore
occasionally need to be replaced. However, the original copper plumbing is
still going strong!

MPRS and Coffey #3

The “new” stills – Coffey #3 and MPRS, Diamond Distillery, Guyana

Diamond’s newest stills are far too large to fit in the
stillhouse. They loom over the distillery and are easy to spot from the nearby highway.

The MPRS (multi-pressure rectification still) and Coffey #3
stills are co-located in an open-air tower near the still house. Both were
installed circa 2011. The MPRS has five columns – the first two operate at less
than atmospheric pressure, making them what’s known as a “vacuum” still. Because
the initial columns operate at a vacuum, temperatures inside the still are
lower causes far less scale to form on the plates, compared to Coffey #1 and #2
stills. The remaining columns of the MPRS operate at atmospheric and high
pressure. The MPRS still can be used to make neutral spirit and a range of light
rums and is so efficient that it can use all of the distillery’s daily
fermentation capacity all by itself. This still can be configured to removing
all congeners produced from the fermentation process, making a neutral spirit
used in creating vodka. Some of the light rums it makes goes into the Diamond
Reserve rums, but not the El Dorado line.

Coffey #3 still, Diamond Distillery, Guyana

The adjoining Coffey #3 still has two columns and also
operates in a vacuum. It’s used to make light and medium spirits and is capable
of making 22,000 LPA (liters pure alcohol) per day.

If you’re wondering why I appear to have skipped over nearly
all the history of the various stills, plus the various marques that they make,
never fear! At the end of this story is a section devoted to all those wonky topics.

Aging

Pretty pictures of casks, Diamond Distillery, Guyana

DDL maintains two aging facilities. The first is at the
Diamond distillery complex, comprised of three extremely large warehouses,
filled with casks stored upright on pallets. To a large extent, they’re very
similar to many other aging warehouses I’ve visited around the Caribbean. But
there was one surprise worth noting: While wandering up and down countless rows
of casks, I noticed notes hanging from some casks, indicating the brand they’re
destined for. I was sworn to secrecy not to divulge them, but it’s easy enough
to guess some of them. Just think of brands selling Demerara rum; I mentioned a
few in Part One, and DDL is the only company making Demerara rum, so do the
math.

DDL’s other aging facility is at Uitvlugt (pronounced “eye flot”), on the other side of the Demerara river by way of a floating bridge. (See Google map above.) Shaun Caleb, DDL’s Chief Production Officer and Master Distiller accompanied me at Uitvlugt, along with the warehouse manager, Jason Bhojedat. The activity level at the Uitvlugt warehouse is substantially less than at Diamond’s warehouse, nearly devoid of people except for two workers. Uitvlugt is where DDL sends casks that won’t be needed for at least three to five years. In computer terms, you’d call it “remote storage”.

Uitvlugt aging warehouse, Guyana

At Uitvlugt, some casks are in racks on their side, while
others are upright on pallets. In 2004, DDL started using pallets for all new
fill barrels. Nonetheless, the sheer volume of casks still in racks, i.e.,
pre-2004, suggest DDL is doing just fine for long aged stocks.

Ruins of Uitvlugt distillery, Guyana
Foreground: Ruins of Uitvlugt distillery. Background: Uitvlugt sugar factory

Peering out the large warehouse doors, I spied the ruins of
the Uitvlugt distillery on the other side of a large, grass-covered courtyard.
What was once an operating distillery twenty years ago is now just so many piles
of rusting barrel hoops, tanks, and pipes, strewn about in a post-apocalyptic
jumble. Luckily, the stills long ago moved to the Diamond distillery. In the
distance behind the distillery remains, the Uitvlugt sugar hums along. But
that’s a story for another time.

While Shaun and I wondered through the rows of casks, the two
workers prepared a surprise: Several casks were lined up, awaiting our return.
Chalk lettering on each indicated they held rum marques I’d only dreamed of tasting
straight from the casks. A barrel thief and some tasting glasses appeared, and we
were transported to Rum Valhalla.

Straight from the cask – Oh yeah!
But wait… there’s more to try!
Rum heaven

At the time of my visit, DDL had about 90,000 casks laid down, with plans to add more warehouses to bring it up to 130,000. That would put DDL’s cask count at more than Destilería Serrallés, and three times what Foursquare and Mount Gay have on hand.

For the most part, DDL relies on ex-bourbon casks. They cask
the rum around 70 percent ABV, a fair bit lower than what it comes off the
still at. Per Shaun Caleb, casking at this lower ABV helps reduces their
typical angel’s share (evaporation) from around 11 percent ABV down to 5-7
percent ABV. As many other distilleries do, DDL periodically condenses barrels
of the same distillate into fewer barrels, thus keeping them nearly full and
further reducing evaporation.

Blending

All Twenty-four of DDL’s marques

As with just about everything else at Diamond, DDL has made significant
investments in the blending process, poising the company for yet more growth.

The relatively new blending hall is a quite an impressive
feat of automation. Two rows of 50,000-liter stainless steel tanks hold the
various liquids needed for the target blend. The blenders sit in an
air-conditioned room with a computer that drives all the pumps and valves
needed to filter, blend, and dilute a product to the ready-to-bottle state. A graphical
display of all components and fluid flows makes it easier for the operator to
stay abreast of things.

Blending tanks, Diamond Distillery, Guyana

One further point in regard to blending: Per Shaun, all of
DDL’s colored (aged) rums are chill filtered prior to bottling, thus reducing a
hazy appearance in a customer’s bottle at lower temperatures. To chill filter,
the liquid is reduced to -20c for 24 hours, then passed through filters at the rate
of 300 liters per second.

Naturally, DDL does its own bottling, and there’s an extensive bottling line on site at the Diamond facility. However, it’s fairly typical for companies to request no photos in this area, so I can’t share anything other than to say it was quite impressive.


As a final note on my DDL experience, I came away very much
believing the company is well positioned for further growth. The company has
invested extensively in upgrading technology, equipment, and processes. More
importantly, it’s investing in its people. Guyana has had a “brain drain” with
smart people leaving the country for greater opportunities elsewhere. What I
saw at DDL was the investment in people for the long haul, not just to fulfill
a particular position. A common theme with the people I met is that they were
hired out of college or shortly thereafter. They then rotated through various
stations, e.g. process chemists, aging warehouse, distillery, blending, and so forth.
Team members have a detailed understanding of what other teams do, creating a
deep bench that DDL can rely on as they merge the past and future of rum
making.

Fully understanding Diamond’s full complement of stills is
quite a challenge. Harder still is keeping track of which estate some stills
came from, and some moved several times! And it’s nearly impossible to remember
all the various marques and their associated stills.

Using several sources, including Marco Freyr’s astoundingly
detailed reference,
I’ve made a Cheat Sheet of sorts to assemble all the key information in one
place. If you’re not familiar with estate names like Diamond, Uitvlugt, Skeldon,
Albion, etc., see Part One which covers the consolidation of Guyana’s rum
estates down to just one: Diamond.

A few observations came to mind as I assembled the
information below:

First, while the Diamond Distillery is portrayed as a living
museum of still operational historic stills, it’s only been that way for two
decades.

Prior to 2000, the now-shuttered Uitvlugt distillery held
all the old stills that are at Diamond today, save Coffey #1 and #2 — and
maybe the DHE. Uitvlugt was where the Port Mourant, Versailles, Savalle and
Enmore stills came together first.

Second, the Savalle still is the most versatile in Diamond’s
portfolio. While all the other stills make at most two marques, the Savalle
still make a total of nine different marques. These marques include recreations
of rums the long-resting distilleries: Skeldon, Albion, La Bonne Intention, and
Blairmont.  For this distillery’s marque
list, I’ve put the originating distillery first, and the marque(s) within parenthesis,
e.g. Blairmont(<B>)

My rather intensive effort to document Demerara Distillers Ltd. wouldn’t have been possible without the help of several people. I’d like to thank Sharda Veeren-Chand, Sharon Sue-Hang, Shaun Caleb, Darryl Manichand, Jason Bhojedat, and Komal Samaroo; for spending time with me in Guyana, as well as fact checking afterwards. I also owe a debt of gratitude to Lance Surujbally for his input and keen insights into Guyana.
