I don't remember when I last opened a bottle, but yes it was still hot. It is more syrupy than a bottle of ice wine I bought to try the style. Rather like warm schnapps even when my ice wine was chilled.
I have cut it with juice in the glass and that removes both the hot and syrup feel. If it ever mellows I definitely recommended the kit. As it is now I'd recommend it with comments about it being hot and feeling like a liqueur as one friend put it.
