Got two additions to the brewery yesterday. After many problems holding temperature in my 10-gallon Rubbermaid cooler I replaced it with the same size in Igloo. Will test to see how well it holds temperature this coming weekend. This bit of gear counts as a “tweak”. I was getting good beers with decent body but am hoping for a bit more control. Second addition was a high-pressure tank full of oxygen. Just the welding-grade stuff but with that and the Big Oxygen System from William’s Brewing, I should take some of the guesswork out of oxygenating wort. The most difficult part apart from the price tag – the tank and gas cost nearly $100 – was getting to the welding supply store when they were open. I honestly don’t know how hobby welders get their supplies: The store closes at 4:30!
