Coffee lovers may have noticed a new offering in their local cafés. Cascara is a tea-like drink with a fine, fruity flavor and plenty of caffeine, and it’s popping up everywhere. For this new addition to chalkboards nationwide, credit Aida Batlle.

Batlle is a fifth-generation coffee grower in El Salvador, whose coffees have won international awards. One day a decade ago, she arrived at a coffee cupping —where coffees are sampled for flavor — and detected a pleasant, hibiscus-like scent in the room. When she asked the other coffee tasters about it, they pointed to the husks from recently milled coffee.

“So immediately I got curious with it,” says Batlle. “And I just picked through it, cleaned it, and then put it in hot water, to see what it was like. Then I called my customers at the time, and I was like, ‘Oh, my God, you have to try this. I’m going to send you a sample.’”
