{"RecipeId":85179,"RecipeTypeId":10,"OriginalRecipeId":null,"UnitType":"s","IbuFormula":"t","CreatedBy":121182,"Name":"Black is Beautiful Imperial Stout","Description":"Mash twice, using half of the grain each time. Boil the beer as long as possible. Marcus says he never boils an imperial stout for less than 6 hours. I might just boil for as long as it takes me to complete the second mash (1 hour). I think this will be ~3 hours total, which is a lot of propane.\n\nTo each mash, add 8 g Calcium Carbonate, 2 grams calcium Chloride, and 1 gram Gypsum.","ImageUrlRoot":null,"StyleId":"20C","StyleName":"Imperial Stout","BatchSize":6,"BoilSize":8,"BoilTime":180,"Efficiency":0.75,"DateCreated":"\/Date(1592721362397)\/","BrewSessionCount":1,"MostRecentBrewSession":16440,"Og":1.0787604166666667,"Fg":1.0196901041666666,"Srm":48.309375373646574,"Ibu":55.679767806279372,"BgGu":0.70695115849792611,"Abv":7.6200703125,"Calories":271,"AverageRating":0,"TastingNoteCount":0,"Fermentables":[{"Per":"59","Amt":"10","Ppg":"37","L":"1","Use":"Mash","Id":"452797","IngId":"3","Name":"2-Row - US","CustomName":"","Rank":"2"},{"Per":"12","Amt":"2","Ppg":"37","L":"1","Use":"Mash","Id":"452798","IngId":"152","Name":"Flaked Oats - US","CustomName":"","Rank":"4"},{"Per":"6","Amt":"1","Ppg":"34","L":"350","Use":"Mash","Id":"452799","IngId":"53","Name":"Chocolate Malt - US","CustomName":"","Rank":"6"},{"Per":"4","Amt":"0.75","Ppg":"32","L":"2","Use":"Mash","Id":"452800","IngId":"78","Name":"Flaked Barley - US","CustomName":"","Rank":"8"},{"Per":"4","Amt":"0.75","Ppg":"33","L":"120","Use":"Mash","Id":"452801","IngId":"509","Name":"Crystal 120L - CA","CustomName":"","Rank":"10"},{"Per":"4","Amt":"0.75","Ppg":"25","L":"300","Use":"Mash","Id":"452802","IngId":"51","Name":"Roasted Barley - US","CustomName":"","Rank":"12"},{"Per":"3","Amt":"0.5","Ppg":"34","L":"250","Use":"Mash","Id":"452803","IngId":"50","Name":"Chocolate Rye Malt - DE","CustomName":"","Rank":"14"},{"Per":"1","Amt":"0.25","Ppg":"25","L":"500","Use":"Mash","Id":"452804","IngId":"56","Name":"Black Patent Malt - UK","CustomName":"","Rank":"16"},{"Per":"6","Amt":"1","Ppg":"46","L":"0","Use":"Late","Id":"452805","IngId":"153","Name":"Table Sugar - Sucrose - US","CustomName":"","Rank":"18"}],"Hops":[{"Amt":"1.5","Type":"Pellet","Use":"Boil","Min":"60","Day":"0","AA":"10.1","Ibu":"37.0562404197778","Id":"482011","IngId":"173","Name":"Belma","CustomName":"","Rank":"2"},{"Amt":"2.5","Type":"Pellet","Use":"FlameOut","Min":"0","Day":"0","AA":"5.8","Ibu":"0","Id":"479290","IngId":"3","Name":"Cascade ","CustomName":"","Rank":"4"},{"Amt":"1.5","Type":"Pellet","Use":"FlameOut","Min":"0","Day":"0","AA":"10.1","Ibu":"0","Id":"482012","IngId":"173","Name":"Belma","CustomName":"","Rank":"6"},{"Amt":"3","Type":"Pellet","Use":"Boil","Min":"10","Day":"0","AA":"7","Ibu":"18.6235273865015","Id":"482013","IngId":"10938","Name":"Flameout correction","CustomName":"","Rank":"8"}],"Yeasts":[{"Atten":"0.75","Id":"125940","IngId":"6412","Name":"Imperial A10 Darkness","CustomName":"","Rank":"1"}],"Others":[],"MashSteps":[{"Heat":"Infusion","Temp":"155","Time":"60","Id":"60108","IngId":"9","Name":"Saccharification Rest","CustomName":"","Rank":"1"}],"Steps":[]}
