2013 BCBS ABV Question

Not sure, but When I tasted them side by side I couldn't tell the difference.

 

Based off over my tries brewing higher ABV beers it is hard to get all the sugars out of the malts, my guess is that they had two brew days and one was more efficient than the other.

 

Different batches yield different ABV's. If I recall I think 2014 had 3 different ABV's.

 

Yep!

 

Basically it's batch variation. The beer is blended out of the barrels, and I'm assuming not all of the barrels will fit in the blending vat. I've heard that the barrels themselves can have anywhere from a few cups to a couple gallons of whiskey left in them, so that'll up the ABV of individual barrels. If a few more of the extra boosted barrels go into one batch, that'll contribute it.

It's true that super high gravity beers can be very difficult to brew at home, but I have to think that GI can crank out the base beer the same every time. Maybe not though...

 

I guess this all makes sense, but why are other BBA brews pretty consistent on ABV batch-to-batch and year-to-year? Why wouldn't they blend multiple batches into one consistent brew (at least for a given year)?

Sort of on topic, and maybe it's been posted and I missed it, has 2015 ABV been released? Seems to be a downward trend over the last couple years.

 

I could be wrong but the reason why other BBA brews are pretty consistent is they don't make the VOLUME that Goose island makes.. Goose makes a CRAP ton of BCS so as someone else said their isn't enough room in the blending vat for that much beer!

But since GOOSE is owned by IN bev I am sure they will have the money to buy a big enough one in the future!
