Notes

The fermentable "Blueberry Honey" is actually 1 pint (16 ounce) of homemade blueberry jam. This was diluted with some water then heated to pasteurize then cooled to yeast pitch temp and added to primary with some pectic enzyme.

The Koji grains are added to aid in souring along with the Philly Sour yeast.

Squeezed bag at end of mash. 5 1/4" liquid level. About 1.8 gallons.
Mash finished ~149' A little trub left behind in transfer.
O.G. is 1.082 added 5g Monk yeast and 6g Philly Sour.

7 days S.G. is 1.022
nice pink color, sour but not puckering. After 2 weeks the S.G. was the same so I mini kegged it and accidentally overcarb'd. No head retention, ABV ~7.5%, nice sour notes but finishes dry like a sparkling wine.
Needs refinement. Suggestions?
