Quote from: RPIScotty on June 17, 2016, 07:14:46 amYou would get an oxygen scavenging effect if, rather than say Spunding in the keg, you bottled off the fermentor at a calculated gravity and allowed the beer to naturally carbonate in the bottle by reaching terminal gravity. You would have active fermentation at that point. Priming sugar is an easier solution as you don't need to guesstimate when to rack. I'm wondering if anyone has compared primed, naturally carbonated kegs to force carbed kegs to see if one stales faster than the other.

I believe they have and found that it doesn't do it and the only way, still, is to spund.

From quick googling I discovered some brewers force carb but comply with reinheitsgebot by using CO2 collected from fermentation. I wonder if those beers taste any different from traditional methods.

I would love to hear some responses from those who sample some of their first brewtan beers. Denny and one other brewer from Brews-Bros (Chils) has reported back after sampling their brewtan beers. Denny is cautious but seems to think that "something is happening" which is encouraging and Chils response was "This stuff is definitely changing something in the beer. The non-brewtan batch still has some harshness to it." and he was comparing a brewtan batch vs. a non-brewtan batch of the same recipe. Again, some understanding of what the product does and how it may impact different beers or brewers (oxidation, water composition, etc) would be great. I hate mysteries. I would prefer to understand what is happening.
What I do plan to do and leave in the beer fridge for 6 months or so, to judge the impact on shelf life.
Did you use a copper chiller Denny?

What happened to traditional lagering schedules? I'm starting to wonder if what "they" are trying to duplicate is not traditional german beer, but the taste of macro produced Bitburger.

I don' think so..at least, I'm not. For one thing, my kegs will take 2-3 months to kick, so there's a medium term test. For another, I simply haven't had time yet to brew something to set aside. That's why I'm not making any grand pronouncements at this point.
