100% Brett L souring with lacto

[wswing86]

Hi all, venturing into the world of sours and basically making a Frankenstein beer....I have a 100% Brett L beer that has reached a expected FG of 1.008 and I want to rack it into some cherries and pitch some lacto in there to sour. Any suggestions? Do I need to combine with Pedio also? Very first sour so any feedback welcome!

Lacto works best if you pitch it at the beginning. Once the Brett starts producing alcohol, the lacto will be inhibited. If I read correctly, you're already at 1.008, so the lacto would have a pretty limited effect. If you want it more sour than it is now, the cherries and carbonation will help, but Pedio would help more. I'd throw it on the cherries and see how you like it in a month or so. If it's good, then drink it. If it needs more sourness, then add Pedio (either from a lab or from some bottle dregs) and be prepared to wait a long time.

Ok, so even in a low alcohol brew, the lacto won't work? I'm roughly 5-6% ABV. I figured the extra sugar from the cherries would have some effect with the lacto

Most lacto gives out around 3-4%, but there's a lot of variation between strains. Even if the lacto survives, the brett will eat plenty of the sugar from the cherries, although many lacto strains will eat things brett doesn't in a sacch-less fermentation.

With alcohol and hops in there, you will be very unlikely to get any souring from lacto. Don't waste your time.

Check out the wild brewing section for info on lacto and pedio. Lacto likes really warm temperatures and some people sour with lacto around 90-110 F for a few days then pitch a yeast and/or Brettanomyces which is a yeast.

UPDATE: I did a couple things...no lacto upon re commendation. I racked a 100% Brett L saison onto blueberries and dumped some of the leftover yeast cake into the Carboy as well. I also racked a pale I have going into cherries and added some of the yeast cake from the 100% Brett L into that Carboy as well. Should i add any extra sugar or pitch more fresh Brett to increase the funk? Side note, added some oak chips also...this is gonna get weird....should I add any Pedio for giggles?
