Hi,
I have a question about extreme slow fermentation. I brewed a Heineken clone all grain beer. The grain was 18 lbs of German Pilsner and .5lb German Carafoam. The 18 lbs of grain was the last of a 55lb sack that I bought 13 months ago uncrushed. I crushed the grain on brew day.
The brew day went uneventful with a OG of 1.06 yielding about 11 gallons. Cooled the wort to around 70F, aerated with oxygen for two minutes and added Wyeast #2007 Pilsen Lager yeast. One 5 gallon fermentor starter to ferment about 24 hours later. This fermentor had the bottom wort from brew pot and had lots of hops and garbage in it. The second 5 gallon fermentor did nothing for 3 days. I didn't do anything and was planning to dump it this weekend. Then 5 days after adding yeast it started to ferment. Today on day 6 the fermentation process is going strong, pushing wort through my airlocks.
So my question is, do you think the beer is ok? I have never had fermentation take 5 days to start. I thought the grain may be old but that doesn't explain the first fermentation taking off and the second dormant for days. Off flavors? Should I dump it?
Thanks
