Averagely Perfect Kölsch - "Kölsch-Vid 19" Kölsch All Grain (with extract option) Batch Size: 5 Gallons into fermenter (5.05 gallons including trub prior to xfer to fermenter) OG: 1.045 FG: 1.008 ABV: 4.8% IBUs: 25 (Tinseth) Mash Efficiency: 70% Grain Bill: 7.88 lbs German Pilsner Malt 0.88 lbs Wheat Malt Hop Schedule (Pellet Hops): 60 Minutes --0.66 ounces Hallertau Mittelfrüh (3.8% AA) --0.66 ounces Tettnang (4.4% AA) 5 Minutes --0.35 ounces Hallertau Mittelfrüh (3.8% AA) --0.40 ounces Tettnang (4.4% AA) Yeast: Wyeast 2565 Kölsch Water Profile (overall): Ca: 51 ppm Cl: 53 ppm SO4: 51 ppm Process: - Recommended Mash: Single Infusion @ 149F, 60 Minutes - 75 Minute Boil - Fermentation: 62F - Cold Condition 20 days at 36F - Carbonate to 2.5 volumes CO2 - This recipe assumes pellet hops, with a 10% bonus utilization due to pellet form, and a wort absorption of 0.025 gallons of wort per ounce of hops. The Standard Tinseth formula assumes leaf hops (without the 10% bonus utilization). If you will use pellets, but don't believe in the pellet bonus (or believe in a different bonus), adjust. If you will use leaf hops, adjust (for both utilization and for greater wort absorption). YMMV. - I used my own boil off rate (in conjunction with hop wort absorption) to determine my starting wort volume, which impacts hop utilization. YMMV. Adjust as necessary. Use your software. - Anything you change that relates to absorption or other wort losses will change the total fermentables you need to get out of your mash. So you may need to adjust the grain bill up/down. - If your hops have different Alpha Acid percentages, adjust as necessary. - This recipe assumes 70% Mash Efficiency, a little higher than BYO recipes (for example) assume, but probably closer to the average efficiency on this forum based on what I've seen over the years. YMMV. Adjust as necessary. Other Notes: Extract Option Replace the Grains with 4.46 lbs of Pilsen Light DME and 0.81 lbs of Bavarian Wheat DME. (Assumes Wheat DME made from 65% Wheat and 35% Pilsner.)
Hmmm. Link isn't clickable here. So: https://www.beeradvocate.com/commun...oelsch-vid-19-how-we-got-there-thread.641551/
Thanks for posting the water profile! Boiling this > 60 minutes there seems to be a sweet spot. 90 minutes is too long as well. I've done two batches of Kolsch at these. Will try the 75 next.
