I didn't have much luck searching, so I apologize if this has been asked and answered before--
Does anything need to be done to sanitize or pasteurize fresh raspberries when adding to a lambic? These are fresh from my back yard, so I'm sure there are all sorts of critters on them. The alcohol level is fairly low, and it isn't very sour yet, but will the lacto/pedio/brett be able to overcome whatever is on the berries already?
I froze the berries ahead of time, but so far I've thought about heating them slowly in the freezer bag in 160-180 degree water to pasteurize them, maybe smashing them and dosing with campden, or soaking them in vodka. Raspberries grow mold so quickly in the fridge, and although they looked fine when I froze them, I'd hate to put the time into this beer and have it ruined by something growing on the fruit.
