About the same as Blue Light (110 cal). When I did my yearly tour of the Boston Sam Adams brewery this spring, the bald bearded guy from the commercials was working, and I asked him how they keep the taste so good on the light beer. He told me that essentially since Sam Adams is so hoppy to begin with and has the bold flavor, they really don't have to change the recipe or water down the light recipe much-- just slightly change the grains content and fermentation time to cut down the sugars and alcohol content. Anything else would have been a state secret. But he did say they spent about 3 years trying to get the light recipe right, and some of the other light recipes they tried that weren't successful ranged from so different they wouldn't have sold, to -- his words-- "more bland than koala piss in a can"
that is nice bonus change
