If
you're just discovering spirits let us help you
understand all the styles and tastes. Spirits
are one of the most versatile products that you
can use for a classic drink or any cocktail
recipe.
What
Are Spirits?
Alcohol,
in its basic meaning, is a hydroxyl compound
such as ethanol or methanol. Fermentation is the
process by which an organic substance (usually a
sugar) is converted by a single-celled
microorganism such as yeast into alcohol. A
spirit is distilled alcohol. Spirits
distillation is the process of heating a
fermented liquid, evaporating off the alcohol as
vapor, and then condensing it back into liquid
form.
How Are Spirits
Made?
Spirits
can be made from any organic substance that can
be fermented to create alcohol. Most alcoholic
beverages are made by fermenting fruit or
grain-based solutions. A still extracts alcohol
from a fermented liquid by boiling it and then
condensing the alcohol vapors, which evaporate
from the boiling liquid at a lower temperature
than water. The alcohol content can be further
increased by additional re-distillations that
further concentrate the alcohol and reduce the
total volume of liquid.
The
first and most basic type of still is the pot
still, which is an enclosed vessel (the kettle
or "pot") that narrows into a tube at the top to
collect alcohol vapor that evaporates when the
fermented contents are boiled. The tube bends
downward off the top of the pot and runs through
a bath of cold water. This causes the alcohol
vapor to condense back into liquid and drain
into a container at the end of the tube. Most
pot stills are made from copper. They are
considered "inefficient" in that they carry over
a percentage of water and chemical compound
vapors along with the alcohol vapor. This
"inefficiency" can be considered an advantage
when producing spirits such as brandy and
whiskey that have distinctive flavors.
The column or continuous still has two enclosed
copper or stainless steel columns. The fermented
liquid is slowly fed down into the top of the
first column while steam is sent up from the
bottom. The rising steam strips the alcohol from
the descending liquid and carries it over into
the second column where it is re-circulated and
concentrated to the desired percentage of
alcohol. Column stills are more "efficient" than
pot stills in that they extract a higher
concentration of alcohol. They are favored for
neutral-flavored spirits such as vodka and white
rum and also for industrial alcohol.
