Meet Our Farmers & Producers

Spent Goods

One night at his local pub, founder Dihan asked the question we’ve all been too shy to ask: What happens to all the grain used to make beer?

After learning that most spent grain, especially from smaller breweries, ends up in landfills, The Spent Goods Company was born.

Spent Goods' delicious beer baguette is used as the crostini for this recipe!
