The role of oxygen in brewing

Not sure if we've captured this somewhere...I didn't see it on a quick search of the forum or 'Advanced'

Hi All, been lurking a while but not contributing....
I've noticed that many very very good breweries in Germany use a lauter grant, in their traditional brewhouses (at least on the surface - robots out back filing kegs). I've had world class beers out of such places. this doesn't seem to align with the low O2 hot side environments which you may find at Weihenstephan and other large breweries. In saying all this, there seems to be a preference on this website for the beers of Munich, which are highly industrialised, compared to small family artisinal breweries, say in Franconia.

I will say this. I had beers the other day from a brewery with a brand new custom design Kaspar Schulz brewhouse. They are very bright in all departments. Would Schulz be using low O2 technologies in their designs?

Thoughts?

Many breweries keep them there for decorative purposes, especially if they're giving tours, but they're not necessarily used. Of course, some places still do use them.

Yes, generally the beers we discuss are those coming out of very modern, industrial breweries. In my experience, many Franconian beers, and many pub/small brewery beers in Germany in general, are not brewed low oxygen. It makes a different end result, and at the end of the day it's all about what you personally enjoy.

Most likely yes

Many still have the Lautergrants on display (because they are pretty) but they are no longer in use (they are bypassed below).

Every sensible German manufacturer is fully aware of the impact of O2 during the process. KS is not the exception. In fact, they have a superb boiling system (Schoko boiller) which uses evaporation under vacuum to reduce the overall boil time to 30 minutes.

I did the experiment and did a brew according to conventional home brew dogma and one using intert methods and side-by side the result was quite clear.

So, when in doubt, it's best to verify for oneself and make ones own conclusions going forward. Everyone will eventually settle for what suits them best.
