Scope And Argument
Printed pp. 174–195; scan PDF pages 179–200.
Recycled fractions connect one run to later runs, so an individual batch must be interpreted within the larger inventory system.
Literature Note
Chapter 7 describes stripping wash into low wines and selecting fractions during a later spirit run. Recycling heads or tails can recover alcohol and change the composition of future charges. Routing to wash, low wines or a separate recovery run creates different process histories. The book acknowledges that definitive steady-state congener evidence is limited; repeating a route does not prove the inventory has stabilized.
Cognac-style first-pass selection differs from the whisky-style strip discussed in the book. Those terms identify process arrangements and cannot establish a product's legal identity. The 10–80–10 approach is a comparative collection scheme expressed against expected total distillate, not a percentage of the original charge. Its fixed divisions do not replace product-specific sensory and analytical evaluation.
The numerical production example on pp. 180–181 uses gallons. A 1,000-gallon charge at 22–23% ABV contains 220–230 gallons of absolute alcohol. Even the lowest stated combination of heads, hearts and tails contains about 234.5 gallons of absolute alcohol; the upper combination contains 301. The example therefore fails closure if treated as one actual batch. It is a warning to check arithmetic, not a yield target to copy.
The repeated Alcarde tables are the same sugarcane experiment already discussed in Chapter 3. Geometry, rate, headspace and foaming are plausible influences but not isolated variables in every example. For the Academy, the transferable idea is an explicit flow ledger: identify fresh charge, incoming recycled material, outgoing product, future recycle, residue and unaccounted difference.
