Labatt Blue Light low carb beer has 8g of carbs and 111 calories. This makes it the most carb-rich beer that I've tried, and a mere 2g of carbs less than many regular beer!
As you might imagine, since it has practically all the carbs of a regular beer, the body of it is not watery. It's pretty close to a regular beer. It has sort of a light, sparkly flavor to it, with a hint of bitter taste and a very short finish.
I tried this one with a bowl of peanuts, common bar-style, and it was OK. It heads in that "crisp and clean" direction of flavors. Maybe even a bit TOO bubbly for me. But I've already picked on Bud Light at this point for having 6.6g of carbs and calling itself a low carb beer. For Labatt Blue to make that claim with a full 8g of carbs is bordering on silly.
For me, it's just way too many carbs to even fall into the low carb category for beer.
UPDATE OCTOBER 2008: I have gotten the following email from a visitor: "I just started drinking Labatt Select. It is a low carb beer. Carbs 2.5g; Calories 88; Fat 0; Protein 0.8. " I have not seen this in my stores but I will see if I can find it to write it up!
