As I posted in the US05 thread, having a couple of issues with yeast starting.
2 all grain batches, 24l each:
Batch 1 OG 1.059 pitched a re-hydrated 10g dry pack of US05 on Monday 19 Jan. No visible krausen or SG drop over next 4 days, pitched some (not sure how much) rinsed yeast on Friday morning. Went away for a couple of days, and there was krausen when I got home last night, SG as of about half an hour ago is 1.024. Hydro sample was really fizzy into the sample tube, opaque and smelt/tasted 'yeasty'. Maybe some sourness there.
Batch 2 OG 1.062 pitched a 10g dry pack (not re-hydrated) of US05 on Thursday 22 Jan. No krausen whe I got home last night, but a thin one this morning. SG hasnt really moved. I pitched an additional yeast as above just now. Wort still tastes good.
Both worts no chill, brewed 2 days before pitch, aerated by a shake in the cube and a pour from a height into fermenters.
Both yeasts purchased from local shop at same time a couple of weeks ago.
The second pitches are highly likely to be underpitched, along with the failed initial pitches. I don't really get yeast volumes yet, just started to suss out rinsing.
So, what would you do? See both ferments through? Ditch them?
What is the likely effect of the failed ferments?
