I was inputting my recipe for Skeeter Pee. This is just cane sugar, water, lemon juice and yeast (with some nutrients and such). I just put the sugar in the recipe and it didn't calculate the OG, FG, etc. I added a custom item with just 1 lovibond and then it calculated it. For some reason it doesn't like having a lovibond of zero. Recipe for information: http://skeeterpee.com/?page_id=17 Edit: I would also be neat to see more integration with wines/wine yeasts in the future.
