It was bound to happen sooner or later! Two days ago I tried making cream soda:
Will you look at that awesome bottle? How sexy! Unfortunately, the cream soda was NOT sexy because, as tasty as it was, it was not carbonated. The yeast didn’t ferment, or something. It was airtight and sitting around for two days now, but the yeast didn’t do anything. So I had to throw it out. Oh well!
Come to think of it, the problem might have been that I didn’t use a plastic bottle – or something that could expand to allow the carbonation to take place. I dunno. Either way, I don’t really care because I don’t drink soda anyway.
