Notes

Water: Target ion levels under 100 ppm each.
Target mash pH 5.2-5.6 (This winds up to be 5.49 expected with additives)

Idea is to create a wort with low fermentability and even some starch remaining.

Ferment with primary WLP051.

After primary fermentation is complete, rack to your aging vessel of choice (shoot for as low oxygen permeability as possible to limit acetic acid) and add WLP655.

Once souring has reached our satisfaction (8-12 months typically), add the fruit. This series will split the sum batch into two different fruit options for maximum experimentation.

After 2-3 months, rack off fruit sludge and package.
