Hey jdub! I do agree that the OP recipe seems to be high in Cara Munich, but he has had great success with the recipe. Granted judges tastebuds may have changed between 2012, when he first won with this recipe and now. I currently have a Marzen on tap that I love, that only uses 2% CaraMunich. It gets most of it's flavor from Vienna, Light Munich and Dark Munich, so it's rich toasty goodness. It's the
MeanBrews recipe, and in the video he does talk about how this style has evolved over the years and that the percentage of base malts has increased drastically, while crystal malt usage in the style (well in award winning recipes), has dropped from over 12% in the mid-90's and is trending downward to under 5%. The recipe reflects that, with 97% of it being base malts.
On Brewfather, the Mean Brews recipes all list pedigrees, i.e. comp results from those who have brewed the recipe and reported back results. It's got 9 medals, including 1 gold and has scored a high of 45. Here's hoping it scores that high when I send some out!
As to entering yours, that's your call. Maybe throw the Diamond one in a comp as a Marzen and try International Amber with the one with fruity esters? Heck, maybe even toss it in as a Czech Amber.
