It's time to test out the validity of another of Drew's favorite techniques - keg purging.

Breweries spend a lot of time worrying over removing as much oxygen possible from their packages (bottles/kegs). Why? It's pretty well established both in tradition and science that oxygen is destructive to beer flavor and aroma pretty quickly. So packaging brewers do everything they can to reduce O2 levels after their intial injection of oxygen post chilling.

BrewTan - Or Do Oxygen Scavenging Chemicals Change the Beer Character

There's been a big kerfluffle in the online brewing world this year over "LoDO" brewing aka Low Dissolved Oxygen brewing. Proponents of the extremely complex methodology theorize that by reducing the amount of oxygen entrained at all times in the mash or the boil that you prevent oxidative reactions that damage the beer's flavor and reduces the overall malt character.

The reason they're obsessed is they're driven to recreate the "it" character they claim German beers have with their malts that they find lacking in many commercial and homebrews.
