Younger consumers under age 45 prefer light beers and are not being targeted by Mountain Man's marketing.

However, there is risk the new beer may cannibalize existing lager sales. The case analysis examines financial ratios and potential market share and profitability scenarios to help Mountain Man decide whether to launch the new light beer brand.
