Dumping cooled wort onto yeast cake from Czech Amber Lager with both aorund 70F then put in fermentation chamber to cool to 52F

Judged Oct. 2024 at DEA Hoptoberfest. Got a 32. Main complaint was not enough malty richness. Mean Brews used 62% Pilsner, 15% Munich, 8.4% Caramunich II, 4.2% Carafe II (not III) and added 6.9% Biscuit and 3.5% Pale Chocolate. May be worth trying these changes next time. Should increase maltiness. https://web.brewfather.app/share/xOrrcrFhkFy87S

Also, may want to drop the protein rest from 131F to 127F and increase boil from 60 to 75 min.
