So just cracked open my first few bottles of My first attempt at a Gose (full recipe/souring method below.) I'm getting a bit of a Bready/Doughy aroma and to a lesser extent flavor in the beer. Sourness and salt/coriander are a bit subdued vs what I remember Westbrook tastin like, but are relatively well balanced and I'm happy for a first attempt. For my next attempt I would like to reduce/remove the bready/doughy aroma/flavor and was hoping some may have advice on what to change. I'm leaning towards using a different yeast, any suggestions?
Recipe Type: All Grain
Yeast: Nottingham (1 packet, rehydrated)
Batch Size (Gallons): 5
Original Gravity: 1.050
Final Gravity: 1.006
IBU: 6
Boiling Time (Minutes): 60
Color: 3-4SRM
Primary Fermentation (# of Days & Temp): 2 Weeks @ 62F ambient
5lbs White Wheat Malt (50%)
4lbs Floor Malted Bohemian Pilsner (40%)
1lbs Acidulated Malt (10%)
Mashed Wheat, Pilsner and 4oz of Acid Malt at 148F for 60 minutes, then added additional 12oz of Acid Malt to mash for additional 45min. Mashed in this method to allow Wheat and Pilsner to mash at ~5.2ph then lowered ph to 4.7-4.8 with additional acid malt to create wort conditions favorable to Lactobacillus growth and inhibit "bad bugs" (e.g. Clostridium botulinum)
Raised to 169 for "mash out" for ~10min. Used BIAB method, so no sparge.
Boiled wort for 15min to de-aerate as some bad bugs can survive at lower ph but are aerobic (e.g. Acetobacter). Unclear if this step was necessary, but seemed like a reasonable hypothesis, with little downside.
Quickly cooled wort to 110 with immersion chiller then pitched 1 cup uncrushed acid malt (in a sock), covered tightly with Saran Wrap, pushing all air bubbles out and put in a DIY insulated heating chamber set to 110F (had trouble keeping it there as the room it was in was in the 30s and heater was 100W, but stayed above 100F.). Ph of wort did not drop meaningfully over first 36hrs, but then dropped to 3.8 and stabilized there by the 72hr mark. Smell was bready/clean the entire time, no vomit/stinky diaper. Saved a bit of the sediment and have since stepped up several times with 1.035 dme wort to 1L starter so I can re-pitch same bugs in next batch rather than relying on grains for bugs.
Then did the boil as follows
Boil Time: 60min
0.50 oz - Hallertauer Mittelfruh (2.9 AA) for 60min ~5 IBUs
17g Himalayan Pink Salt for 10min
0.5oz crushed coriander for 10min
Cooled to 62F, pitched 1 packet rehydrated Nottingham. Slow bubbling of airlock within 8hrs and vigorous activity by 16hrs. Airlock activity slowed dramatically by day five, at 1 week hit 1.007 and stabilized at 1.006 by 2 weeks. Bottle conditioned targeting 2.9vols.
