temperature stick-on thing has shown the temperature to go from 16-18deg but never above that, and the airlock has more or less stopped gurgling, so I took a gravity measurement - 1004. That's going to be one strong brew!
What next?
I have a few questions about Lagering
1) My greenhouse is currently showing 4 degrees celsius but if we get a milder spell it could go up to 10 or more - but this is the only cool place I have. Is this too cool? especially considering it'll get much colder overnight
2) how long should I leave it in there?
3) should I just move the primary FV in there, or should I rack it into a secondary, or even bottle it?
Now that's half the story, You would really need to ferment the above at around 12 degrees for at least 2 weeks, then run off into a second vessel and lager at as close to freezing as possible for at least 3 weeks, then bottle or keg.
doh! didn't read the above! please ignore
