 It's been at least a year, but it might have been longer than that. Can we do a root beer that's good, grown with stuff that's all available locally in our yards and gardens? I think there's a lot of ingredients you can get there. The wintergreen note has been the one that's been eluding me a little bit for local sources. Basil is something I have not considered. It does have those notes. And the other thing that grows here, there is one more that grows here, and that's going to be your birch.
