Process notes

2017-07-23
At 8:00am temp had dropped to 80°. pH is 4.62, so nothing really happened. This is consistent with what happened in (AM) though.
2017-07-24
At 7:15am temp is still 80°. pH is 4.6. The bacteria could be dead, as they are over a year old from the same bottle that was bought for (AM).
2017-07-24
At 7:00pm pH is still 4.6, so Lactobacillus is probably dead and I'm just going to go ahead with the boil.

High krausen at nighttime. Should've used a blow off. Fermenting at 72-73°.
2017-07-26
Bought 12 pounds of peach (6# white and 6# yellow). Pitted, cut up and put in freezer.

Kegged. Decent peach aroma, but there's a lot of alcoholic bite to this one. Pretty harsh. I hope it mellows. Great golden color. Not getting much saison character.

Tasting notes (6.00/10; 1 rating)

2017-09-17
[6/10] Peach is coming through well. Light orange, pretty hazy. Earthy, grassy peach aroma. Dry, somewhat grassy peachy flavor. Not too bad, but hops could be reduced. The original harsh alcoholic aromas and flavors have thankfully mellowed out. Decent, but not great.
