Notes

BREWGR NOTES

Do again? Hell Yes! Malty, sweet, clear. The best I've brewed so far. Tiny bit over carbonated. I think the extra ABV helped a lot.

MM Kit - Suggested Yeast: S-23 or WLP800, or Wyeast 2001. I used SafLager S-189 that came with Bock kit by mistake. Fermented around 18c.

Used Weyermann Floor Malted Bohemian Pilsner

Attenuation - 79%

Recipe says “floor malted” Pilsner.

10/10 - 6.7%

Recipe OG: 1.056 FG: 1.016 ABV 5.3%

OG 1064. FG 1013. 6.7%
