I'm getting various errors when trying to save a hard seltzer recipe I've made (I know, I know about seltzer opinions, anyway....) When saving the recipe in the editor (both Android-Chrome and Windows-Firefox), a pink error bar across the top says, "Error: Final Gravity is too low: -0/003". It also sometimes shows an error that says the final gravity must be a number. When this error happens, any changes to the recipe won't save. I believe that the error is caused if the final gravity is calculated to be less than 1.000. I'm using only sugar as the fermentable, and yeast with attenuation set to 100%, brewhouse efficiency set to 100%, and a mash steeping step (for a short boil). Including hops or not doesn't get rid of the error.. I've brewed this before and achieved a 0.092 final gravity, but am unable to get the recipe editor to predict anything lower than 1.000 as a final gravity. Dry meads and other brews routinely come in under 1.000, so I'm wondering if this is a Brewer's Friend error or something that I'm not understanding about its use. Screen capture is attached. If this is the wrong forum section to ask, please enlighten me. Thanks!
