The photo below was Brad McGillicutty this morning. He was born on Sunday night and still lives in a bowl. I expect he'll move into his own glass jar at the end of a week. Therefore, this sourdough starter is obviously not mature yet. This fact is not going to force me into following others' instructions and rules.
I think collecting wild yeast will be pretty forgiving and I'm not at all afraid. In fact, I just saved a half can of Vancouver Island Brewing's Twisted Stalk Blackberry Helles. It's on the counter and already lukewarm. I'm going to share it with Brad during his next feeding. Tap water is boring but Brad and I both celebrate complexity, especially as an excuse for beer.
