Kolsch is a great, easy-drinking beer that straddles the boundary between ale and lager. Clean pilsner malt, lager-like fermentation characteristics, subtle noble hopping, and hint of sulfur make this a beer than can be drank by the liter (although it tastes better 0.2 liters at a time in an authentic Stange). Fermented cool using a specialized Kolsch ale yeast strain sets this apart from traditional blond ales you might find at your local brewpub.

Keys to Brewing
- This is a very clean beer with little room to hide. Good sanitation, pitching a healthy culture of yeast in the correct quantity, and solid temperature control will help ensure a quality end product.
- The Wyeast Kolsch strain of yeast doesn’t like to drop bright. I tend to use gelatin to get a beer of brilliant clarity.

It’s been a couple years since I’ve brewed it, but when I did it was excellent.
