14th April 2015 - Mashed at 65oC. Aimed for mash pH of 5.2 (predicted) using:
Lactic Acid (88%): 5.3 mL added to strike water.

23L at 1.035.

pH adjusted to 4.6 after running off to kettle. Bubbled CO2 through the wort to remove oxygen and then wrapped the surface with plastic wrap to avoid oxygen in headspace. Incubated for 10 days between 35-48oC till pH had dropped to 3.3. Added grain 3 times as seemed to stall at pH 4 for quite some time.

24th April 2015 - Boiled, chilled and fermented at 24oC with a brett / sacc starter from 2 bottles of Vieille Ville. 19L at 1.032. Some fermentation of sugars from lactic acid bacteria had reduced preboil gravity to 1.029...

Fri 15th May - Dry hopped with 42g Mosaic

Mon 18th May - Gelatine added to primary and fermentor cold crashed in a fridge set to -1oC.

Tues 19th May - Kegged and pressure set to 1 bar. FG 1.004 so 3.5% ABV.

Tastes great. Nice lactic tang, very drinkable. No apparent Brett character but could be over powered by the acid. No off flavors detected. Ever so slight "grainy" aftertaste that I get in a lot of berliner weisses. Not sure what it is, but at a much lower level than a lot of commercial examples.
