The past year has been a hard one for most beer categories. With the exception of imports—particularly those from Mexico—volume growth hasn’t been easy to come by. That’s led companies to release new brands and packaging formats, but there are only so many ways a brewery can find new avenues to sell more beer. So, in recent months, you may have noticed another tactic: rebates.

Offering money back isn’t new in beer. The largest companies have provided rebates when shoppers buy large packs of Bud Light, Miller Lite, or Coors Light for years, but some craft breweries are exploring this space as a means to boost sales that have otherwise slumped.

Which begs the question: How does all this work? Along with Kate Bernot, Good Beer Hunting’s Sightlines reporter, we’re going to explore what’s going on in beer and why rebates can be an attractive option for breweries. As you’ll come to learn, it’s not just about selling more beer, but also finding a way to get your personal information, which can be priceless.
