fermentation help ? (NB petite saison)

Bubbling is not the best indication of active fermentation. Let it ride for at least 2 weeks, then test the gravity. If it's the same 3 days later, then primary fermentation is done.

 

Personally, I'd let it go a month. No peaking. I'd rack to a bottling bucket and package immediately after that. No reason to be worried about an airlock's activity. ^^^ As said above, it's not an indication that it's done fermenting. What is an indication that it's done is a gravity reading at 1.0xx and a second read three days later with the same gravity reading of 1.0xx. You may bottle after this.

 

3711 ferments out really fast. When i've used that yeast it hit terminal gravity in a few days. That said, if you're not on a time crunch it won't hurt to give it another week.

 

I have used 3711 a few times to make Saison beers. That strain has consistently completed primary fermentation in one week. I kept the beer in the primary for one additional week for some ‘additional’ bulk conditioning.

Cheers!
