General Info
Adjusted to simplify malt bill from the previous attempt - kept floor-malted pilsner, but increased to 70% in the grist; replaced Vienna with Munich II, but only at 21% in the grist; got rid of Golden Promise and CaraRed malts altogether. Kept the touch of Caramunich for caramel / toffee notes, but reduced it to just over 3%.
Saaz are really low alpha this year, so I picked up some Kazbek, a higher alpha hop that have Saazer characteristics, but a bit more floral and citrus notes. Using those in bittering and flavor/aroma additions. Saaz only for aroma.
Aiming at the top end of the style for bitterness - 8 points higher than the previous brew. Inspired by this Zymurgy article.
