I'm new to DIY. I downloaded the calculator (excel file), and it helped me a lot. My first flavor was a simple french vanilla. It's not too bad, I think I might want to increase the flavoring though as it's not as strong as I was hoping. I had a small bottle of Johnson's Creek French Vanilla and it's so very nice, like custard. I want to replicate that! I'm using McCormick's French Vanilla ATM, might need to switch that up. I checked the ingredients first, nothing in it that is unvapeable.
Anyhow, I just wanted to say thanks for this forum and the threads/files. They've proven very very helpful.
Next I'll try something fruity, like cherry or grape.
