Instant Coffee Processing
Wednesday, 29 June 2011
Gregg's Instant Coffee is manufactured in our Forth Street Plant
in Dunedin. Established in 1925 when William
Gregg consolidated his import and export business, the plant is the
only Instant Coffee manufacturing facility in New Zealand.
Green Beans are sent to Dunedin in 60kg Hessian
sacks. They're emptied into a hopper...and
from that hopper the green beans are then stored in silos
The choice of bean is one contributor to the flavour
profile. By combining different origins, each with
their individual characteristics, we are able to create a
consistent, high quality flavour profile that Gregg's has become
famous for.
The type and origins of the beans released for
roasting depends on the blend being produced, and
those beans are then dropped into the roaster. The
roasting process is the second contributor to the
flavour profile. During this process the sugars and other
carbohydrates within the bean become caramelised, producing the
coffee flavour that we know and love. The coffee beans are
roasted until they expand and change colour from green to light
brown to dark brown depending on roasting time. A dark,
medium or light roast is achieved by the amount of time the beans
are left in the roaster. Once the beans reach the desired
roast profile we quench them with water to slow the roasting
process. Once the beans are cooled they are ready for
grinding.
The roasted beans then go to a grinding process
where the beans are broken very carefully to ensure that they are a
particular size and consistency. They are then transferred
for the careful process of extraction, where water is added to the
ground coffee to extract a liquor from it.
Finally the coffee goes through the drying process. The
aim is to remove all the water and leave the powdered Instant
Coffee with as much flavour and aroma as possible.
Spray drying may be followed by a step to form the powder into
coarser particles that will dissolve more completely in a
cup. This is called the agglomeration
process and results in granulated coffee.
Since its invention in 1901, coffee drinkers have formed strong
opinions about which type or format of Instant Coffee they
like. While they are all made from pure coffee the processing
methods result in differences in flavour, aroma and
taste.
At Gregg's we take great pride and work hard to create one of
the best quality coffee drinks in the world.
And like the coffee, it's instantly satisfying!
