I've never used these and just got interested when hearing last sunday's Cigar City show. My brewclub is looking for wine barrels to age a group brew in which I'm personally more concerned about as far as quality and contamination and everything involved. I'm thinking the spirals sound like they'd have the same effect even though they don't sound as cool. I saw them on a website for winemakers and was wondering if folks use them the same way, one spiral per 3 gallons for about six weeks total is what one online shop says to do. I will see if my LHBS can get these and if not would like to get them from any BN vendor that carries them.
I've been making a couple RIS's and love 'em. I just picked up a bottle of Great Divide's Chocolate Aged Yeti which used cocoa nibs, oak aging and spices.. I haven't drunk it yet but just got me thinking when I heard this show. Any suggestions, ideas? Thanks!
