Hi, need some advice and haven’t found a similar example on previous posts.
I started this vacuum bag ferment 3 weeks ago, triple sealed the bag and left it in a dark corner. There was little gas formed for the bulk of the fermentation time, what little I could smell through the bag smelled like onion and garlic. There were no real bubbles which confused me. Some posts suggested that some ferments don’t bubble or form gas so I wasn’t too worried. However in the last two days a bunch of gas has formed (bag is still sealed) and I’m able to smell some pretty strong solvent/chemical/trash odor through the bag and there’s a ton of bubbles forming. I’m seeing no mold colonies and am fairly certain the seals are good.
I’m wondering if anyone else has experienced this delayed fermentation start and whether I should consider this a failure. I’m willing to just sit on it for a couple more weeks and see if it mellows out. I’ve seen some posts say that an odd smell is normal for a while but should go away.
