SPIRITS

     

 DEFINITION----A spirit is an alcoholic beverage containing ethanol that is produced by distilling the ethanol produced by means of fermenting grain, fruit, or vegetables----Any potable liquid containing 1/2% - 75% of ethyl alcohol by volume  ---The term "spirit" in reference to alcohol stems from Middle Eastern alchemy---The vapor given off and collected during an alchemical process (as with distillation of alcohol) was called a spirit of the original material


INTRODUCTION---In chemistry, an alcohol is any organic compound in which a hydroxyl functional group (-OH) is bound to a carbon atom, usually connected to other carbon or hydrogen atoms


DISTILLED BEVERAGES---The process of separating  ethyl  alcohol from the rest by condensation is distillation---The boiling point of ethyl alcohol is 78 degree centigrade & water is 100 degree centigrade, it is this volatility that is used for separating the two


COMPOUNDED BEVERAGES---Made by combining a spirit with flavoring substances, ex; Gin----Various types of liqueurs, such as Benedictine, Tia Maria, Crème de menthe  ---Various bitters such as Campari are examples of compounded beverages

ALCOHOLIC CONTENT---The word ‘proof’ refers to the alcoholic content of a spirit----In USA, the 'proof' measurement is twice the percentage of alcohol by volume (e.g., 80 % proof = 40 ABV---V/ V for “Volume by volume," used to describe the  actual concentration of alcohol in a mixture


GAY LUSSAC--According to Gay lussac --100 proof is 57.1% alcohol by volume(ABV)---75 proof  spirit is ---
57.1 X 75
--------------     = 42.8 v/v
100

METHODSOF PRODUCING ALCOHOL,HAS TWO STEPS  FERMENTATION AND DISTILLATION---Fermentation is the action of yeast in a sugar solution, which breaks down the sugar into carbon dioxide and alcohol---CO2 escapes into the air, and the alcohol, a liquid, remains behind in the original liquid, which thus becomes a fermented beverage---Beer and wines are fermented beverages---All alcoholic beverages begin with the fermentation of a liquid food product containing sugar. Wine Beer,Cider,Perry etc are made by fermentation  of grapes,barley,apples,pears respectively. Now if you want to  make spirits which have more % of ethyl alcohol you have to distill also
Ø Formula = C6 H12 06 +H2O---  yeast à    C2H5OH + CO2

DISTILLATION--Water evaporates at 100°c, and ethyl alcohol evaporates at 78°c (to maximum) ---This is used to separate ethyl alcohol from  water & residue, it is of Dutch origin, There are two methods of distillation

POT STILL DISTILLATION--Pots are made of copper, with a capacity 1000 to 1200 litres, also called  alembics.--Copper is a good conductor of heat & does not react with alcohol--They  are supported on brick kilns with fire beneath in group of twos---The wash is filled in the alembics, and it starts heating---Both the vapours of alcohol & water rise up, but more of alcohol as it vaporizes at 78°C---The vapours pass through condensers and condense into the vessel on other side ----First  distillate yields 25 to 30 % alcohol---Second distillate yields 65 to 70% alcohol---Distilled water is added to bring down the strength to 43%.---First lot of vapours are called heads or fore shoots & the last lot of vapours are tails


COFFEY STILL  / PATENT STILL DISTILLATION---ALSO CALLED AS CONTINOUS STILL PROCESS OF DISTILLATION---Invented by Robert Stein which was later modified and patented by Aeneas Coffey in the year 1831---It is a continuous distillation, process---There are two towers 80 feet high---First one is analyzer and second is rectifier---Hot wash is pumped into rectifier column & steam is injected in analyzer---Both  mix up in  baffles (special perforated trays) resulting in formation of vapors of ethanol---The condenser cools and condenses the ethanol vapors, the remaining vapors are re-cycled as spent wash ---The net result is a yield of 96% alcohol
WHISKY---Whisky, or whiskey is an alcoholic beverage that is distilled from fermented grain mash and aged in wooden casks (generally oak)--Grains  used for different varieties are barley, malted barley, rye, malted rye, wheat, and maize (corn)--Whisky derives from the Gaelic word for "water" (uisce or uisge) meaning "Water of Life". ---It is related to the Latin ‘aqua vitae’, also meaning "water of life".


MANUFACTURING PROCESS---OF WHISKY---Barley is screened & then steeped in water for 48 hours---Starch in the barley gets converted into sugar ---The damp barley is then spread out on a malting floor. ---Germination starts and it becomes “green malt”--Roasting i of sprouted barley is  done on peat fire on kilns ---The peat or “reek” adds extra flavor to the barley which is now called “malt”---The roasted barley is crushed in mills to form grist---Grist is boiled with treated water for 36 hours and churned violently in a ‘mash tun’ to reactivate and extract the enzyme diastase and convert the starch into maltose and dextrose---This is called mash---This is completed in 3-4 washings---The first two washings give a semi-transparent sweetish liquid called “wort”---The remaining washings called “sparge” is used with the next batch---The “wort” is cooled to 16 °C and transferred to fermenting vats or steel ‘wash tuns’ ---Now cultured yeast is added for fermentation process---The yeast  convert the maltose in the “wort” to dextrose and then to alcohol and carbon dioxide ---The result is a beer like ‘wash’ with and alcoholic strength of 7-10%-
The wash is distilled in a “Pot Still” which is known as a ‘wash still’ where alcohol separates and condenses as “low wines” which is a fairly weak and impure spirit --The result is then redistilled in another ‘pot still’ called as “Spirit Still”---The first and last distillate called as  ‘foreshots’ and ‘feints’ are pungent, crude and contains high degree of impurities---The main body called as ‘heart’ is a raw colorless whisky with a powerful aroma---Dilution is done using distilled water to reduce the alcoholic strength---The young whisky is pumped into casks of 33-144 gallons capacity where it matures for a minimum legal requirement of 3 years---But usually it is matured between 15 years and beyond---As the whisky rests air penetrates through the pores and mellows the whisky---The damp conditions in the cellar reduces the alcohol content and slightly
increases the volume—

BLENDING was first done in 1853---Usually blending involved combining various malts and grains or whiskies from different distilleries
