I brewed the Bavarian Hefeweizen extract kit a couple of Saturday’s ago (June 1) with the liquid yeast option (Wyeast 3068 Weihenstaphen). I’ve brewed many kits before (at least a dozen)…but obviously not this one!
Firstly, fermentation started more quickly than normal - probably within 18 hours. Secondly, it was much more vigorous than I’ve ever seen - bubbled over my 3-piece airlock on a 6.5 Gal Bucket.
We’re now 12 days into fermentation and I’m still seeing a bubble every 30 seconds or so. The kit instructions say to bottle after 2 weeks, but that sounds like trouble to me if there is still active fermentation at ~68 deg F. I’m hesitant to perform a gravity check - seems like added risk of contamination.
For those that have experience with this recipe - is this normal? Should I give it an extra week? Could there be some “undocumented alien species” growing in my beer causing the extended fermentation?
Thanks,
Bill
