I must be May, because May is the month where malternative producers roll out their new flavors. But this year, Diageo-Guinness USA is doing something a little different. In a bid to enter the FMB 16oz singles can segment in c-stores, and to possibly fill the void left by Sparks and Tilt when they yanked the stimulants out, DGUSA is set to roll out Smirnoff XBT, a Smirnoff Ice line extension with a "bold citrus flavor" that is "cut with citrus", as it says on the can.
