If you poured your new batch over the old trub while it was still hot then you may have cooked your yeast.tag1260 wrote: ↑Tue Jan 10, 2023 4:53 pm OK. I AM reading through this thread but it IS 154 pages long. I'm on my third batch but it went a lot longer than I planned (cleared and settled) but the taste isn't too bad. However, my new batch of sour mash isn't firing off yet but it's only been 12 hours. The last batch was bubbling away in about 5 hours. Did I let it go too long? Will it eventually start up? Should I pitch a little bit of yeast to it?
Thanks
Put your ear to the fermenter and you'll be able to hear if the yeast are doing their thing (The rice crispies sound if you're from a country where that reference makes sense!).
