Spirit Production Flashcards
What is a spirit?
distilled beverage that contains alcohol
Why are they called spirits?
Alcohol stems from Arabic word - “al-ko’hl” - the 8th century meaning of this word is “spirit” - which means both ghost and “essence”
Spirits produced from starchy materials -eg, rice or potatoes- require a ….. process
conversion process known as saccharification - typically accomplished by heating the starch to trigger the production of particular enzymes which then create a chemical conversion of starch into fermentable sugars
starchy grains that undergo an enzymatic conversion ferment into a “beer” of -% ABV
5-10 ABV
water boiling point
212 F
ethyl alcohol boiling point
173 F
Distillation process is contingent on this simple fact
water has a higher boiling point than ethyl alcohol
highest abv possible in commercial distillation
96.5
congeners
compounds such as acids, esters, aldeydes, fusel oils, and other alcohols developed during fermentation
heads aka foreshots
first part of the distillate to come off the still - contains lots of volatile compounds. may be discarded
tails aka fents
last part of the distillate run - includes fusel oils, acetic acids. may be discareded
center part of the distillate
heart
Rectification
process of concentrating the alcohol content in a liquid by repeated sistillation
the early method of determining the strength of distillate
each quantities of spirit and gunpowder were mixed, and a flame applied.
no burn = too weak
burned too brightly = too strong
even burn with a blue flame = proven to be 100% pure , this is now known as 100 proof
Pot still has two essential parts
the still itself and a worm condenser
