Hi, quick Q. I noticed that my last brew was tasting sour/acidic last night when bottling. Never had this before, and reading around I'm putting this down to possible infection by Lactobacillus. Naturally a bit gutted as I was looking forward to the bitter! Anyway, main query is - do I need to think about throwing my FV? I was going to soak it in a strong solution of VWP, but just want to check if this bacteria is easily removed? For extra info...I always clean my FV well after use and sanitize using boiling water and no-rinse sanitiser before filling. I've been brewing outside for ages and cool relatively quickly using an immersion chiller. I don't open the FV once the yeast is pitched, however I did notice that I hadn't clipped the lid on tightly this time (don't think that made much difference). I'm putting this down to being unlucky, but any extra advice is welcome. Cheers.
