So I want to add some Rasberries and lime to a wheat beer that is fermenting. I have frozen raspberries (from the store) and like juice. Do I need to soak these in vodka for a period of time to sanitize? And how much is a good amount for 5 gallons?
...Also, the raspberry pure will be full of seeds, make sure to throw it into a hop bag before going into the secondary.
Slight update: 150 degrees for 20 minutes will suffice to pasteurize fruit enough that it won't infect your beer.I agree with Nosy, heating and pureeing them ahead of time not only sterilizes, but will help break them down, and add more flavor.
Advice on the limes- Don't add any of the pith- section out the fruit, and use the zest if you like, but the white fleshy pith will lend a very harsh, unpleasant bitter flavor.
