Lacto

Post by weisseguy » Wed Aug 08, 2018 8:53 pm

I’m trying to propagate some Lacto from 2-row using my dehydrator as an incubator. It’s been 48hrs & the pH seems to have stalled around 4.5. It’s got a nice tartness to it but I’ve read I need to get it lower if I’m going to use it to Sour a 5/5-5gal batch. I’m incubating at 115°F. I just dropped it to 95°F but I feel I’m just guessing at what I’m doing wrong. Any & all help is appreciated!

I made my first few sours this summer and I used Jimmy’s method from Mashed In.

It’s preferable to have the Ph somewhere around 4.2 I think for the lacto to propagate. The low PH also helps inhibit enterobacter and other unwanted growth. However that doesn’t mean that you won’t get a decent starter going at your higher PH. The lacto will produce the acidic environment it prefers

lacto, beer yeast, and the like while naturally work with a solution to create a favorable environment if we help them along. They need the same elements the rest of us need.

All my sour beers and sour starters I adjust them down to 4.5-4.2 with lactic acid, and make sure to keep them at proper temps and free of oxygen at every step. Only ever went wrong for me when I haven’t meticulously followed that.

Interesting. I’ve also been told that Kefir is a good source too.

It’s doing this now...I’m thinking something else got in there before the Lacto could take...
