So I made a saison with an expired smack pack, I put it in secondary after 10 days and the fermentation seemed to stop. I was taking specific gravity readings at my work and it was stuck at 1.023 for a few weeks. I tried increasing temp by putting it in my garage and getting my usual fermentation room hotter but to no avail. I then pitched another smack pack on it and it stayed the same FG after 5 days so I racked into bottles with 3/4cup sugar and left it in my garage for good measure. I checked up on it after 3 days and it's already carbed. Should i expect bottle bombs? And if so what can I do to prevent it?
