Ok, so I was interested in trying my hand at a sour beer and have also been trying to reduce my alcohol intake. I have been drinking a lot of brewdog's AF beers when at home.
I decided to do a kettle sour with hibiscus flowers as the flavoring instead of fruit. I'm doing a minimal berlinerweisse for the malt.
I aimed for 5gal (20l) in the fermenter. I used a 110v brewzilla.
Here is my bill:
- 3lb 2row
- 2lbs wheat malt
- 16oz good belly mango-flavor probiotic drink
- 7ml lactic acid
- 3oz dry hibiscus flower in boil (5min)
- Safale 05 dry yeast
- No hops
Steps:
- Heat 5gal water to 168°F
- Mash in, hold at 168 x 1hr
- Drain the grains
- cool to 90°F
- Add lactic acid to get pH to 4.5
- Add good belly, cover with plastic
- Set temp to 85°F and wait
- When pH reaches 3.2 - 3.4, bring to boil for 10min
- Add hibiscus, boil for 5min
- Cool to 80°F, rack to sterilized fermenter, pitch yeast.
SG 1.026
Lessons learned:
Boiling soured wort in the house makes the house stink. The wife was not impressed.
Pitching yeast at higher temps than 100°F kills the yeast.
Morebeer takes 4 days to ship a simple packet of yeast from one state to the next.
Beer is currently happily fermenting at 65°F. I'm going to float another couple of oz of hibiscus as a "dry hop" in a couple days. I'll attempt to update this post with FG and tasting notes when complete. I hope to end at 1.010. That'll put it around 2%.
A lot of airports are designed in a hub and spoke configuration where each spoke is lettered. You may have the A spoke, B spoke, and C spoke. Gates on these spokes are numbered sequentially starting at the hub. Gate A1 is right next to the hub and Gate A40 is near the end. Usually, there are two TV screens between most gates. One for arrivals, one for departures. Flights are listed by destination and time. Figure out where you are, figure out where you need to be. Find the correct spoke and then find the correct gate. There are shops and restaurants everywhere in case you need anything, but everything is super expensive (captive audience). Stay hydrated.
