I've been playing with this and there seems to be many places you need to update the code to get it to wok. Particularly in passing the database connection to the managers. I've got iy working now but need to finish it up before sending it back to GitHub for inclusion in his repository.
I just finished bottling this and it was excellent! I added potassium sorbets to stop fermentation a day before bottling. Then I back sweetened with half a can of limeade concentrate. I love this recipe! Thanks!:)
