DISTILLATION
Purpose of malting is to make stench molecule accessible for breakdown to fermuratable sugars & Maximise the level & enzymes. Starch granules is covered by cell walls. In other words to get the starch, you first need to breakdown both to cell walls & Protein matrix in order to reach the starch. The Malting process controls these actions & if also produce enzymes responsible for breaking down the starch into sugars.
Distillation Process
STRIPPING RUN
1
-
First goal of distillation :- alcohol concentration
-
Stripping Run aims to concentrate alcohol.
-
Fast and dirty Run
-
Bring the base beer or wine from 8 -10% to 30-40%.
-
Result -> low wines
-
A rough Semi finished product is need for future refinement.
SECOND DISTILLATION
2
Goal -> To separate cutting out the alcohol.
Heads, hearts, & Tails.
-
Not all alcohols are created equal.
-
Good alcohol ‘Ethanol’ boils at 78.3°c.
-
Acetone (56°c); Metnanol (65°c) Ethyl Acetate (77°c).
-
propanol (97°c); Butanol (118°c); furfural (170°c).
-
Acetone + Methonal + Ethyl = LBP Acetate = Heads
-
Propanol + Butanol + furfural = HBP Tails.
-
Like with water & alcohol mixtures light fractions come over first.

ALCOHOL SEPARATION
-
Second goal of distillation : Alcohol separation.
-
Finishing Run teams to separate alcohols.
-
Slow and clean run.
-
Make cals.
-
Brings the 30-40% low wines to 65-96%.
-
Result:- Spirit.
-
A refined product sometimes in need of further aging.
