I currently live in China and have had to get pretty creative in terms of air locks- for my latest airlock i cut the top of a water jug and cemented it to the carboy rim and stopper with regular wax (by first melting it and then sculpting it to the sides like clay). anyway, a small piece of wax accidentally fell into the beer...... Does anyone know for sure if wax should mess up beer? does anyone know what wax is exactly made of????????
