I went to a welding supply store to ask for a bottle of oxygen. The manager asked me what I needed it for, and I told him I was planning to add oxygen to beer prior to pitching yeast.
He said their bottles of oxygen also included acetylene (not food grade oxygen). I decided to pass on what he had and went to Home Depot, instead. Problem with Depot is that a couple blasts from one of their bottles and it's empty. My question to you guys is whether oxygen with acetylene is a definite no-no ... and should I go to a medical supply store, instead? I will tell you that adding oxygen in this fashion produces an exceptionally quick start to fermentation ... which was a problem I was having when making 10-gallon batches.
