So I'm 4 batches into my 5-gallon extract hobby, and I have yet to use any of the additives that came with my kit. I got the "upgrade" kit because it came with a hydrometer, primarily. (Also, Palmer's book, said additives, wine thief..etc)
So if anyone can explain the following little bottles I have, and if they're even necessary, I would appreciate that.
Fermcap-s (stored in my fridge) "Add 2 drops per gallon at the start of fermentation"
Biofine Clear (stored in cupboard) "Use 1/4 tsp to 2 tblsp in 5 gallons after fermentation is complete"
Whirlfloc Tablets "Add 1 tablet per 5-10 gallons within last 15 min. of boil"
As I've said, I haven't used any of these, and If I don't need them, I sill have the book, thief, etc.
