2020 Christmas Trees being Fertilized with Guinness Beer

If the tree you buy for the holidays this year has trouble remaining upright, here’s why: Guinness has been using stale beer to fertilize Christmas trees.

The unusual fertilization method came about after coronavirus shutdowns left Guinness with hundreds of thousands of unsold barrels of beer, says Aidan Crowe, the company’s director of operations. “It’s been a tough time in the brewery,” he says. “That’s why we took the decision to bring back all of the beer.”

Crowe says the majority of the beer taken back from bars and nightclubs was donated to willow and Christmas tree farms, which have been using it to provide nutrients to the trees.
