Before filing a bug report of being blocked from making a certain spirit, please ensure the spirit should have been distillable. These are in order of most commonly missed.
1) You have *ONLY* the correct type of sugars. Most recipes other than vodka and aquavit require just one type of sugar in the spirit. For example, If you try to make pisco (which requires 3 fruit sugars) and you have 4 fruit sugars, 4 alcohol, 1 yeast, and 1 mixed grains, you have made Vodka, not Pisco because of the mixed grains. 2) You have the correct barrel type in your store room 3) You have the correct number of sugars and the correct type of sugars. 4) You have purchased the recipe cube 5) If you are distilling a signature spirit, it must include a particular type of sugar, for example, Grapes or Potatoes. This can be your signature ingredient or an ingredient from the premium market.
