Tried the first bottle (way early, I know, but I didn't use much priming sugar since this style gets low carbonation) tonight. Here's a picture side-by-side with the original:
It generally needs more of everything- body, sweetness, head, color. I think improving my crush and doing a second decoction will help. It has a slight sour finish, but it's quite good. By itself I wouldn't complain, but compared with the barley version it is clearly inferior. The coconut isn't even detectable at all.
