Cascara is the dried husk of the coffee cherry, the fruit that surrounds every coffee bean before processing. For most of coffee's commercial history it was simply discarded as a processing byproduct. Brewed as tea, it turns out to have a genuinely pleasant flavour profile in its own right, and using it rather than composting it is a small, real sustainability win at the processing end of the supply chain.
What it actually tastes like
Cascara's flavour depends heavily on where it's from. Latin American cascara tends to run bright and fruity, hibiscus, cherry, mango notes. Asian-origin cascara leans earthier, closer to dates. Either way, it's distinct from coffee itself, closer to a fruit tea than anything coffee-flavoured, though it does carry a modest amount of caffeine, well below a coffee's worth per serve.
How to brew it
Hot brewing. Use a ratio of roughly 1 part cascara to 25 parts water by weight, around 14 grams of cascara to 350 grams of filtered water. Water temperature in the 93°C to 96°C range works well, similar to a standard coffee brew. Steep for 4 to 10 minutes, most people land on 6 to 8 minutes as the sweet spot, tasting as you go since cascara's strength varies more between batches than coffee does.
Cold brew. Use about 30 grams of cascara to 360 grams of water, and steep in the fridge for 12 to 24 hours, the same patience cold brew coffee rewards. The result is smoother and less acidic than the hot version, worth trying if the hot brew's brightness is more than you want.
Why it's worth using rather than discarding
Coffee cherry processing generates a genuinely large amount of fruit waste relative to the small amount of bean inside it. Using cascara, rather than letting it rot or sending it to landfill, is a straightforward way to get more use out of the same harvest, and it gives producers who choose to process and sell it a second product from the same crop rather than none.
The takeaway
Cascara is a good example of a byproduct turning out to be worth keeping on its own merits, not just as an environmental gesture. It's simple to brew, distinct in flavour from coffee itself, and worth trying if you can find it from a roaster who processes it properly.
