pitching rate question

baer19d · 11-23-2009, 05:03 AM

Would one packet Safale US-05 be enough for a 10 GAL batch?

Only with a very low OG, see http://www.mrmalty.com/calc/calc.html

you can ferment w/ a single cell but I would use 2 packs

I agree, that looks like an underpitch without calculating it.

Just an note, there is an excellent article on pitch rates in a recent issue of BYO. I can not recall the issue's date but it is the one that has several article on yeast and yeast handling.

If I pitched on pack of yeast last night (thats all I had) and pitch a second one this evening everything should workout all right, right? Even if fermentation has started?

I did that once before and it worked out fine. In fact just recently I pitched the wrong yeast for what I was making. I pitched a semi out of date WLP300 and meant to pitch wlp380. So I just added it the next day and it took off fine and the Hydro sample tasted good. So I am sure it will be fine
