So, I have a german pilsner in my primary at 50 degrees that's been fermenting for 21 days. During the brewing, I couldn't find my Irish Moss. I'll be racking the lager to a keg this week (day 24) and lagering until the last week in June (roughly 12 weeks spent lagering). Can I add anything to the keg when I transfer in order to clear the beer, or should I just extend the lagering time? I'd like to have this beer ready for the 4th of July. Feedback would be appreciated.
