I was wondering how much acid blend I should add to a 2 gallon batch. I'm pretty sure I'm supposed to add to the bottling bucket right before I bottle to add some tartness.
Well, I normally just taste it too see how it is, then try 1/4 tsp per gallon, give it a gentle stir then taste again.... etc
But I don't use a shop blend, I use 2 parts malic 1 part tartaric. I don't use any citric unless I've made a batch with 'citric fruit' and no, that doesn't just mean orange/lemon etc....
