The Ginger Man has released their list of Glass Nights for the month of January (sorry, late on posting this and missed the first two already, too busy drinking beer and not posting about it):
18th - Magic Hat frosted glasses
25th - Rahr mugs
The glasses are available starting at 6:00pm and only one glass per person with purchase of the beer of the day. As always, the glasses are subject to change and only available while supplies last.
