It’s not inedible but it certainly isn’t something I’d want to drink a lot of. It picks up all sorts of tastes from the tree and tubing and it doesn’t have the good caramel-analogous taste of syrup yet. It’s noticeably sweet though. Think sugar water with a hint of tree bark (which is basically what it is). I’d recommend tasting it once or twice if you haven’t for the novelty, but yeah it’s not very good unboiled.
