Short story...
First brew with the grainfather after 5 years break from brewing. previously have done 50+ AG brews.
Recipe was mainly BB ale malt with some wheat, flaked wheat and munich to 1046.
single step mash at 67 for 60 minutes.
aerated by holding the outlet pipe of the grainfather up high and dribbling the wort into the fermenter from a height. good foam on top.
pitched two packs of US05 onto the foam, a bit of clumping occurred because I was clumsy.
Fermented at 17-18 degrees - just in a room in my house but it is a fairly constant temp in there at the moment. I put my fridgemate probe straight into the top of the wort after sanitising it. it got as high as 19 degrees once and dropped to 16 once. Good Krausen and solid airlock activity after 14 hours. it was about the time it dropped to 16 that it stalled...
airlock activity stopped after about 3/4 days, i took a gravity reading out of curiosity and it was 1025. sealed it up nice and tight and airlock activity resumed.
it then blooped away for another days slow but steady and stopped today. that is exactly 7 days after I pitched the yeast. so today I thought it was done and added a dry hop addition. took a gravity and too my amazement it was still at 1024. only dropped one point!
so I gave it a swirl, currently sitting at 18 degrees. had a taste and it actually tasted fairly finished. not really sweet, if anything quite bitter, even a bit bitey, which might have just been the freshness/greenness. only hopped to 20 IBU. so since it tasted quite done I thought it might have been a dodgy sample, so I took another sample but it was the same.
the only other thing I did differently was added a tablespoon of ph 5.2 solution into the mash and 10g of calcium sulfate.
pretty weird. Think I will get a starter going with some more US05 tomorrow if I have time to get some from the LHBS. hopefully the swirl will get her going again.
