Today’s Solutions: December 18, 2025

Turning food waste into something valuable. That’s something we love at the Optimist Daily. Just last week, we wrote about a brewery in Brooklyn turning old bagels into delicious craft beer. Today, we present to you a brewery in England that is turning another wasted breakfast ingredient into beer: cereal.

Last year, Seven Bro7hers breweries as they’re known teamed up with BrewDog in Manchester to whip up a milkshake IPA called “Cornshake,” which naturally used leftover Kellogg’s Corn Flakes in the mash. The brewers didn’t think the beer would be on the market too long because they used Kellogg’s branding on the label, and sure enough, Kellogg’s called the brewers. But instead of being mad, they were thrilled with the idea, leading to a collaboration with the cereal king to start creating new beers from cereal waste.

As you might expect, a mass producer like Kellogg’s lets a lot of food go to waste during the quality assurance process: Some flakes are too big. Some are overcooked. Some colors are wrong. Instead of going in the box, that leftover cereal goes in the trash. For now, however, those wasted flakes are being turned into new beers such as the Throw Away IPA—a hoppy IPA created with those rejected corn flakes.
