Notes

2021 session was on spot. A little high OG. But on point otherwise. Needs better head retention though. More wheat malt?
2022 updated w/ ingredients and using Grainfather. Forgot the wheat malt but found a Kolsch malt I'm trying. Also want to try a step mash because I can. Thinner mash. Also splitting w/ some distilled water to soften up the profile
2023 trying some aciduated malt and wheat for head retention
2025 swapped Munich for vienna, switched to WLP029, swapped wheat for CaraFoam. All distilled/RO water.

Wlp029 allegedly clean and crisper than wyeast 2565 which is creamier and “fruitier”?
