Boil for 15 minutes after sparge to kill any wild bacteria or yeast in wort.

Cool remaining wort to 100 degrees. Use lactic acid to lower PH to 4.5 and and pitch lacto. Purge o2 with co2 and seal mash and boil with saran plastic wrap. Hold at 100 degrees until the ph is down to 3.2-3.3. 18-48 hours

Once target ph is reached, boil wort for 75-90 minutes to reduce DMS until 5.5 gallons is collected. Add the hops, yeast nutrient, and irish moss the last 15 minutes of the boil. Cool to 65 degrees and transfer to sanitized fermenter. Aerate with pure O2 with .5 micron stone, pitch yeast starter, and ferment at 67 degrees until complete. Increase temp 1 degree per day until temp reaches 72 degrees. take gravity ready and sample finished beer.

Cold crash to 35 degrees. Add 5 oz amoretti pineapple flavoring to sanitized keg purged of O2 with CO2. Run low psi into liquid post as you siphon beer to keg to minimize oxygen exposure.
