Biere de Mars Attacks!

My first attempt at a biere de mars was a compilation of leftover ingredients cobbled together out of leftover ounces of hops and a dunkelweizen that never got brewed (see Ratchet biere de mars). Although it eventually turned into an interesting beer, it is barely reminiscent of the French biere de mars style that is a cousin to the German marzen (and not too far off from vienna and oktoberfest beers). I wanted to give this style another go with a legitimate biere de mars recipe, hence this recipe was concocted. Originally I planned to brew this beer in March 2014 but I never got around to it so I am brewing it now because I have the room to brew this one gallon recipe and I need to grow up my lager yeast for several other lagers I want to brew in the coming months.

This recipe is modeled upon the biere de mars recipe in Farmhouse Ales but with an unusual mix of French Aramis and Celeia hops to create an unusual citrusy take on the biere de mars style. Saaz and Saaz-like hops might be more appropriate for the style but I don't think the citrus notes from these hops will be entirely unusual. New Belgium's excellent biere de mars had lemon peel and lemon verbana and those lemony flavors worked well. I expect to capture the same compatibility but with a slightly different flavor profile.
