It's hard to make a beer go flat while tring to keep it from oxidizing

Because I'm a mad scientist, and my brew club has categories for "things". I am trying to get a weiss beer to go flat, so I can infuse it with spices, then re-prime it and let it battle carb.

It is not easy to get a beer to go flat, when you're trying to keep it from oxidizing at the same time!

If you have kegs, you can disconnect the gas and pull the release valve every few days...
