I mixed some DME with some water in an empty peanut butter jar and left it on my window sill for about a week, opened, until it started bubbling. I threw it in a gallon batch of 0.5 kg DME, 50 IBUs of B Saaz and some Juniper Berries. The culture actually took and it's bubbling away quite well now with a VERY yummy looking foamy head, better than I've ever gotten with any commercial strain actually. The smell is somewhat lambic-y, but it's very big on the green apple, green banana and yogurt smells and very little of the funky "barnyard" ones. So has anyone else tried using wild yeast before?
