Looks like some Chardonnay barrels will be filled with Apricot Blonde for a couple of months: http://blogs.denverpost.com/beer/2012/03/07/dry-dock-branching-sours/2844/
They've done a sour apricot a few times in the past (usually for special occasions) and it's phenomenal. The article mentions a recent one, but I'm thinking back 2-3 years ago to their anniversary parties and summer fests. This might be a totally different animal, but I have high hopes.
Agreed. They've done a great job with this beer in the past. I'm looking forward to some 750's being released.
