Yeast starter (1x Propper + 1x Imperial 'Dieter' G03 Yeast, started in stir plate for 10 hours), half poured from stir plate flask per fermenter.
4/25/2021 2:04 AM over 3 years ago	+10	Fermentation Complete	1.010	11.75 Gallons			4/25/2021 9:18 PM over 3 years ago	One of the lightest (and fully fermented) beers I've ever made. Light finish with a faint wheat note, body very light, malt gentle on the palate and hops are barely there. I'm looking forward to tasting this in a few more weeks at 44-48F and carbonated.

Notes

A gentle Kölsch for springtime. Baldur was know as a mild-mannered, all-around likeable guy. This beer is made in that spirit, to be sipped in spring sunshine.
