| Distillation
The word brandy is derived from the Dutch term "brandewijn,"
which translates to "burnt wine." It described wine that had been "burnt" or
boiled, in order to distill it. The boiling point of water is 212 degrees
Fahrenheit , while that of alcohol is 176 degrees Fahrenheit. Therefore, if
heat is applied to an alcohol containing liquid and the temperature is kept
below 212 degrees, all of the alcohol may be separated from the original
liquid. The process of distillation is simply the boiling off of the
alcoholic vapors from wine or any fermented mash through intense heat, and
collecting them as condensed liquid.
At Brandy Peak, we begin the distilling process by
first, carefully selecting the best, fresh fruit available for fermentation.
Because of this, our process usually begins in early Fall, when the pears
and grape varietals are harvested. Fully ripened, the fruit is crushed and
fermented. After fermentation, when the natural sugars have converted to
alcohol, the fermented mash is put into one of our unique wood-fired pot
stills for distilling. Using a mixture of different woods harvested off the
property, the pot still is heated. When the still gets hot enough, the
material will begin to boil. Since alcohol boils at a lower temperature than
water, the boiling liquid will release the alcoholic vapors before the water
boils. The vapors will go through the pipe to the condenser, where
they are cooled to liquid form, then gathered in glass containers. This
distillate, like all spirits when they first come off a still, is clear and
colorless.
Stills
There are two basic kinds of stills; pot stills and
continuous stills.
Continuous or column stills utilize two enclosed
copper or stainless steel columns. They allow for a "continuous" feeding of
fermented liquid to steam heat, producing a very consistent, if unexciting
product. This method is very efficient, and can distill up to very high
strength. But in this process, the congeners, or flavoring elements, are
lost. The resultant product, however, is very smooth in texture and finish
when reduced to bottling strength, and thus has definite commercial value.
Most large scale producers use the continuous stills, many of them
multi-storied in height.
The continuous still method came about in the early
nineteenth century, when Robert Stein invented and put into production a
still which successfully distilled a continuous flow of fermented beer into
good spirit. Stein’s invention was demonstrated before the Excise
authorities in London, and a Dublin excise officer called Aeneas Coffey took
Stein’s design and further improved upon it. Coffey’s development of the
still has since spread around the world and formed the basis of continuous
distillation.
Up until the development of the continuous still,
distillation was always carried out in variations of the pot still method.
This method of distillation allows for a careful crafting of the final
product, but the pot still has to be recharged after each individual
operation.
Then, as now, the pot still is usually made of
copper. This is because copper is a very "clean" metal, removes unwanted
sulphides, is resistant to acid and is an excellent conductor of heat.
This "old world" style of distillation, with the
use of pot stills and careful crafting of each production run, is
re-emerging in popularity. It is an art form that allows us at Brandy
Peak to produce the many award-winning fine brandies, grappas and
eaux de vie.
