I'm making a wheat beer, recipe from the complete joy of home brewing, and wow its active. Made this thing 10 days ago and the airlock is still bubbling, a lot! I had to put a blow off on it for 3-4 days then switched over to the airlock. Whats the longest this should keep going? This is my 5th full batch so bear with the dumb question but this is the longest I have seen yet. Going to keep it in the primary for minimum 2 weeks and if SG hits its going right to bottle.
