I get regular e-mails from the publisher of the DBBB, the Domestic Brewers Bottled Brands, with trends in beer sales and other press release information. Today’s e-mail included a chart of IRI Data by beer style showing sales of beer from the beginning of the year through November 6th of this year. IRI is short for Information Resources, Inc., a company that surveys sales of beer (and everything else) from over 15,000 retailers (mostly groceries) in the U.S. As a result, their data is invariably skewed toward the national and regional brands since it doesn’t take into account direct sales and sales from small mom & pop stores. I used to get IRI data from almost every medium to large brewer who called on me when I was a beer buyer for a chain of liquor stores. And while it’s not accurate for craft beer in specific, it does give you a general idea of certain trends, especially when you follow it over a period of time.
