Low-carb beer is simply beer that has lower carbohydrate content. An example of this could be Corona Premier. The carbohydrate content in such drinks is converted into carbon dioxide and alcohol, leaving very little sugar and calories behind.
We all probably know that the non-craft breweries make their beer lower in calories through a mixture of lower alcohol and higher adjunct brewing. I wanted to shoot as low as I can without sacrificing the flavor we all have come to love about craft beer.
There are many ways to make light beers that are low-calorie and low-carb. A well-known method is incorporating certain enzymes into the mash or fermenting beer. Those enzymes are added to the beer until its carbohydrates are broken down into simple sugars before thinning out the mixture with water.
For those of us looking to loose a few pounds or cut down on carbs, low calorie home brewing gives us a chance to be creative, cut down the calories and still enjoy our favorite beers. An average 12 oz (1/3 liter) serving of average strength beer contains about 150 calories.
