Hey & Help…
I’m an extract brewer and have been using the standard carbonation drops (the sugar candy things, not the NB vitamin looking things) with perfect results until recently.
My general rule of thumb is to not make anything under 7% ABV. The carbonation drops have been perfect, seriously perfect, with every batch until my last two. Every step of my process is dead on, perfect fermentation, gear is ultra clean, my water hasn’t changed, and allow time for beer to condition.
I thought my last flat batch, a IIPA, was unusual. Then I just opened an imperial stout and it’s flat too.
I have no clue what’s going on.
I always use a secondary and then transfer to the bottling bucket with the siphon.
My bottle capper is solid - i even bought a new one between the last two flat batches.
