Initial brew in 2019 without lemon zest or lactose and was very nice. Blueberries from Trader Joe's ("wild" Canadian). Added to fermentor frozen, but this only made the beer pink instead of purple like original and Modified versions.
2020 Changes. Reconfiguring the water additions a little bit. I will add zest of 2 lemons in late boil. I plan on cooking 1/2 of the blueberries (2 of 5 lbs) until better broken down and blending the remaining 3 lbs frozen in a sanitized food processor. Also, swapping out S04 for Ringwood as I heard good things on the escarpment webinar about the esters it produces. I'll oxygenate it well after pitching and ferment mostly open. Diacetyl rest because ringwood is a butter bomb (which I think will work ok here to have some residual "butter").
Copied this recipe and tweaked it a lot to accommodate philly sour. Added in dextrose for making acidity and then after a few days I will add the London yeast for english yeast character after a few days with the dry hop and fruit. Took out the maltodextrin and added back some of the lactose the original recipe had on Wesbrews.
