30 minute boil.
A Whirfloc tablet with 7-8 minutes left in the boil.
It takes 10-15 minutes to chill from boiling to about 70° and then another 20 minutes or so to get cooler (lagers) and then I would pitch. Less time for ales.
Once the beer goes into the keg it sits at about 35° and that time might be short (like 3-4 weeks) or longer but I notice the chill haze even on beers that sit cold for 10-12 weeks.
I use a gel solution on every batch. If it's yeast haze then why is the beer only hazy when the beer is cold while the warm sample is clear?
The haze seems to come and go and I do switch grains regularly. Could be Briess, Rahr, Best Malz, GW, Montana Craft, Swaen, etc.
