I’ve never understood why more attention isn’t paid to demographics! Thanks to the remarkable efforts of the Census Bureau, we KNOW what the population will look like in 5-, 10- and 15-years (which is, by the way, the reason there is little excuse for overcrowded schools).

Yesterday, I shared SeekingAlpha’s conclusion that demographics trends may be unkind to Wal-Mart. Today, I am going to share SeekingAlpha’s conclusions about the impact of these same shifts on beer. According to SeekingAlpha.com, Gen Y will “ undoubtedly break the beer drinking records set by Boomers in the late 1970s and early 1980s.” Here is an editted version of their analysis:

“As 78 million Baby Boomers started to exit the prime 21-34 beer drinking age bracket in the early 1980s, they were replaced by a much smaller potential-beer-drinker cohort, Generation X. This led to years of flat to declining volume in the beer industry. Now, as Generation X ages out of the prime beer drinking age, it is being replaced by the much larger Generation Y. This new generation of potential beer drinkers is currently mostly age 24 and under … and it is the largest generation in U.S. history. In 2008 alone, more than 3.8 million members of Gen Y turned the legal drinking age of 21, 100,000 more than turned 21 in 2007. Their entrance into the prime beer drinking age bracket may already be making a difference. Industry data indicates that beer consumption has been on the increase since at least 2006.”

Which types and brands of beer will benefit most from the shifts? According to their analysis, first and foremost it will be the big U.S. breweries (and their foreign owners), due to their sheer volume – 80% of sales. But the biggest gains will be seen by microbreweries, which are currently just 6% of sales, but already outpacing the rest of the industry. In 2007 the growth rate of microbreweries was estimated at 12 percent, (vs. 1.4 percent for the large domestic brands and imports). In 2008, microbreweries increased volume by another 5.8 percent, and increased sales more than 10 percent.

This analysis brought to mind an email I received from Marty Predd, a twenty-something Research Associate at Brand Amplitude who recently moved to Portland, OR from Indianapolis. He shared this a few months ago when we were working on a project for an imported beer client:

“As you may know, Portland is a mecca for craft beer…we have the most microbreweries of any city in the country, and I can think of about a dozen that are within walking distance of my loft. My girlfriend and I partake regularly and I’m sure we’ve become beer snobs to some degree. Bars we used to love in the Midwest seem less appealing now when we visit because of their limited selection of mostly huge national beers like Bud or Miller, or mega imported brands like Guinness, Smithwicks, Heineken, etc. With the exception of PBR, which has a nostalgic status in dive bars here, I can’t think of the last time we enjoyed a mega beer brand that’s not based here in Portland (i.e., Widmer).”
