Stella is my beer of choice if I'm having more than a few, its light and no hangover in the morning. Stella on tap, for whatever reason, is much better than the Stella in the bottle/can.
If I'm looking for a treat any beer made by Belhaven is win every time, a great Scottish brewery that does not get enough credit. Might be a little pricey, $24 for a 6 pack, but its a nice beer to drink if you are just chilling.
The Wee Heavy is a strong flavored beer that is nice on those cold winter days. I
The Scottish Ale has a nice molasses after-taste that is best paired with a beef/steak/hamburger dinner.
Picaroon's (great micro brewery out of Fredericton) Winter Warmer is a great fire-side beer in the cold winter months, it has a very strong flavor and will warm you up
, you can't go wrong with any of their beers but Winter Warmer is one of their more unique and special beers.
Prince Edward Island Brewing Co. (Gahan) has a great Honey Wheat Ale called the Sir John A's, it is without a doubt a great beer for those warm summer nights. They are also a wonderful micro brewery, based out of Charlottetown, you can't go wrong with any of their beers.
