Notes

Full volume mash in 20 gallon electric Blichmann Surface kettle with false bottom.

Added 1 tsp lactic acid post-boil. Let kettle sit over an hour with immersion chiller connected to recirculating ice water bath to reach pitch temp of ~48* and allow wort to drop clear of break material. Kettle was covered tightly with foil during this time to keep bees/bugs out.

Pitched three 200B packs of WLP802. Two packs were very fresh and the third was about 1 month from expiring. Cell count should be ~400B.
