A very unpleasant sourness.

Awful smell and taste...

It was pretty sour and a little burnt. I normally don't like sour beers, but I didn't mind it this time.

Unusually sour in the foretaste along with burnt notes. Ashtray water comes to mind. Slight coconut and a burnt bitterness follow and build up over time. It takes a lot to make coconut gross for me, but this one nailed it.
