Esselon utilizes a vintage 1969 Gothot, 23 kilogram (50 lbs)
natural gas fired drum roaster. The roaster has been completely
refurbished, and is the workhorse that produces the outstanding
coffees that Esselon offers. Our roaster is in operation every Monday and Thursday roasting
beans for use in the caf, retail sales and online order shipments.
Our buyers are constantly sampling new green coffee arrivals to
select the best overall coffee from each region and /or
producer/supplier so we can offer esselon customers the best
overall cup of coffee and coffee based beverages. Starting with the
finest green coffee beans we can locate, painstakingly roasting in
small batches and cupping each roast to ensure we sell finest
The roasting process starts with weighing the green coffee beans,
dumping the green coffee into an elevated hopper, adjusting the
internal drum temperature , dumping (introducing) the green coffee
into the preheated drum.
We then monitor the rise in temperature and the time, documenting
each step and minor adjustment, increasing or decreasing the amount
of fuel to either speed up or slow down the roast, during selected
milestones of the roast.
The coffee reaches one of these milestones at first pop”/”crack”,
the next is for the second pop”/”crack”. For the various roast
profiles, the coffee may be dumped from the drum before second pop,
at this time, or well into second pop.
Once the coffee is dumped from the drum into the cooling tray, air
is drawn thru the roasted coffee to cool as quickly as possible to
prevent it from roasting further. Once cooled, the roasted coffee
is weighed again to determine the degree of moisture that was
removed to ensure the proper roast. Finally, the beans are packaged
for either wholesale, retail or for use at the caf.
