I'm strongly suspecting ....... or some other ridiculously addictive substance. Besides that, it has a banana hint on inhale for me and a nutty hint on exhale. I think it's a mix of a banana nut bread, atomic cinnacide, tasty finger, butter rum and magic. I've gone through about 12oz of it and still love it like a fat kid loves cake (and at 280#, I know about cake).
What's important....It's made with love.
and yet, somehow, I don't think a juice named 'Geoff's love juice' would sell nearly as well...
