General Info
Yet another iteration of Humptoberfest. After last year's disaster, I'm hopeful the changes in recipe, water, and fermentation will produce a great autumn lager.
Changes this time:
- Slightly different hop regime - all continental varieties, however
- Performed a triple decoction for more melanoidins and to be true to style
- Added brewing salts to my base water to approximate the Vienna region
