hey everyone. i made a batch of 5.4% cream ale and ended up 6.5 gallons instead of 5. The extra 1.5 gallons went in a second keg and is carbed up. Since it's got alcohol and CO2, do i need to worry about sanitizing any ingredients that i might want to throw in the keg to experiment with flavors? Example would be blueberries, or mint leaves, or both. I'm thinking as long as i put them in a pouch or something to contain the mess, an infection or tainting the beer is very unlikely correct? i usually just tincture but feel like trying something else. thanks.
