Recently, I've tried 2 unique beers from the Great Lakes Brewery: Orange Peel Ale and Pumpkin Ale.
According to the sales, you can only find this two beers once a year during Halloween time.
The orange peel ale is nice. It has an slight orange flavour and is very refreshing.
The sales person highly recommends the pumpkin ale, but it wasn't as good as I expected. The pumpkin flavour is minimal. I think it's because pumpkins don't really have a strong taste, but I would expect this beer to have a lot of pumpkin flavour.
It's nice to try them for fun, but it's not something that I would buy on regular basis. They are ok for once-a-year type of beers.
