Hopefully AB doesn't change the recipes
That hasn't been their pattern in the past. Generally the recipes do change.
Of course the recipes change. They
HAVE to change.
Look, a big brewer like AB-Inbev buys a small craft brewer with the intention of ramping up production so they can maximize their distribution network, benefit from economies of scale, and increase profit. That means ultimately, they need that craft brewer to start producing A LOT more beer. They can't do that on the craft brewer's equipment, because they're very likely already operating at almost full capacity. So they need bigger equipment, or to brew it at AB-InBev's facilities.
If I take one of my house beer recipes over to your setup and we brew it on your equipment, using your process, it's not going to be anywhere near the same beer. Maybe I batch sparge, but you fly sparge. Maybe I just vorlauf a couple gallons with a pitcher, but you have a HERMs setup. You have higher efficiency than me. You brew electric, I brew gas. You're on city water, I'm on well water.
Now add in scaling issues (I brew 5 gallon batches, but you've got a 35 gallon setup), and variation in ingredients (I brew mine with a stash of 2012 Simcoe hops, but you've got the 2014 crop with lower AA%), and it's not going to be the same beer. AT ALL. Same recipe, vastly different beer.
So what do we do? What's more important? Staying faithful to the recipe and producing a wildly different beer? Or altering the recipe to take all those factors into account in an attempt to reproduce the character of the beer as closely as possible?
So we adjust the recipe. We tweak it to take all those things into account, and voila! We've got a beer that's pretty damn close to the one I was brewing on my smaller system.
But, purists scream, "They changed the recipe!"
Yep. So what? Do you like the beer or not?
