I had bottled a hefe using TAP and bottles. TAP is down to half. I am going to a BBQ and was considering bring the TAP, but wanted it full. Any problem cracking open several bottles and CAREFULLY pouring bottles into TAP container, Aside from possible oxidation by introducing O2? I plan on the finishing the TAP container the same day, so i am not overly worried about oxidation. Anything? flat beer? other problems???
