Every brew gets an A5 note sheet in a ring binder with a reference number, name, ingredients (with costings), method, sugar calculations, dates strained / racked / filtered / bottled (with gravities), final alcohol content and any other notes or comments.
Beers just get a brew number written on the cap, and I also alternate cap colours.
Some juice wines go into 660ml clear cider bottles with gold crown caps which just carry a brew number and clue to contents, e.g. âWOW 1208â which would represent my 8th brew in 2012.
Other wines get a self-adhesive label bearing brew number, name, date started, bottling gravity and abv.
I work in the printing trade and occasionally stand in for the works manager / guillotine operator, so I have a box full of business card sized offcuts from sticky labels which would otherwise have ended up in the bin, and I only keep those whose glues I know will soak off in hot water.
