What makes Yuengling Light a light beer?
Light beers are held longer in the Mash Tun during the brewing process so that the enzymes in the malt have more conversion time of the starches into fermentable sugars. This leaves fewer unfermentable sugars in the mash that would equate to more calories. The fermentable sugars are then converted to alcohol during fermentation; thus, resulting in fewer calories in the final product.
