This beer is inspired by a trip to Cologne that I took with my family while visiting Europe a few years ago. After touring the Cologne Cathedral ("Dom"), we stopped in at a nearby bakery for some treats. As we were looking through the counter at the lovely pastries, an old woman behind the counter came around and swatted away the hand of my 5 year old daughter as she was pointing at a pastry she wanted (even though she wasn't touching the glass). I immediately gathered the crew and we promptly left without ordering, but not before telling off this old hag with a few choice German words. Alte Hexe is "old hag" or "witch" in German, so this beer is dedicated to her.

3L starter at 1.046 with 2 packets of WLP029 Kolsch yeast. Should be about 1 million cells per ml, more than adequate.

Wonderful white winelike flavor quite reminiscent of the varieties available in Cologne.
