I had no idea nitro beer was a fad. I remember when Guinness draught in a can with the widget came out but didn't know the different gas was part of why I liked it. I am not a fan of carbonated drinks except for perhaps, Vernors ginger ale. Coffee, and water (not bottled, or iced) have been my two primary beverages since I was a teen. Every once in awhile I'll go on a homemade iced tea kick.
Now, the nitro beer with, or after dinner is something I look forward too. After a trip to Ireland last year, not really excited about most of their food, I really got to give it a try.
