Mango Sour (Berliner Weisse)

Mash and collect enough wort to do a 15 minute boil to pasteurize. Chill to 95-100F (35-38C). Measure pH. Add Lactic Acid (88%) to wort until pH reaches ~4.5. Pitch quart of Good Belly Probiotic Juice Drink into kettle. Hold temperature at 95-100F for 24-72 hours. pH should be between 3.2-3.6. Place kettle back on fire, hop and boil as normal. Chill and rack to carboy. Pitch 2565 ferment at 68F (20C) for 3-4 days. Raise to 71F until fermentation is complete.

Mangoes: Purchase 5 lbs (2.25 kg) of mangoes. Peel, de-seed, and cube the fruit. Place fruit in a freezer storage bag. After two days, thaw and crush fruit with a rolling pin. Be careful not to damage the bag. Refreeze and repeat until the fruit in mushy. After primary fermentation is complete, rack beer into secondary vessel on top of the frozen mangoes. Check daily to punch down floating fruit to avoid mold. Leave for 7-14 days (to taste).

Prepare two vanilla beans and sanitize with enough vodka to cover the beans. Place beans in a sanitized dry hopping vessel or muslin bag. Place in secondary vessel and check flavor daily. The vanilla should be very subtle. Once the taste is where you like it, remove beans. Package as normal.
