I think this might be my favourite brand of beer. For a while, the LCBO was selling the rum finish and irish whiskey finish flavours, so I decided to try them before they stopped selling it.
Whiskey finish: manly, woody, not as sweet. There's a strong flavour, and a slight coffee taste. It has the highest alcohol content of the three at 7.4% ABV. It's okay, but not my favourite.
Rum finish: less sweet and a bit more alcoholic tasting than original. I might prefer it to the original since it is less sweet.
Original: vanilla hint, goes down easy. It is the most sweet-tasting of the three, and has a lighter colour.
As I was drinking all three bottles simultaneously, I thought they went great with Cheetos. :D
