Roasted by Mom 'n 'em in  Cincinnati, the result is bright, eccentric, and expressive, with taste notes of macerated berry, black tea, and demerara.

🌎 Origin: Cauca, Colombia 

⚗️ Process: Honey / Blackberry Co-Ferment 

🔬 Variety: Caturra 

🔥 Roast: Light 

About the Roaster:
Brothers Tony and Austin Ferrari opened Mom 'n 'em Coffee in Cincinnati on Mother's Day 2019 as a tribute to their hardworking mom. Since early 2023, they've been meticulously sourcing and roasting bright, expressive coffees from producers like Andrés Martinez.

James N. ★★★★★

This is the most creative coffee I’ve brewed in months—the blackberry note is bold without being sour, and it lingers in a really pleasant way. I’ve been experimenting with pour-over just to catch the full fruitiness.

Brian ★★★★★

The blackberry fermentation comes through beautifully, adding a juicy sweetness without overpowering the coffee's natural complexity. I've been brewing it as a pour-over and the aroma alone makes my mornings feel special.

Julian ★★★★★

The blackberry co-ferment definitely delivers on the funky sweetness — I could smell the berries as soon as I opened the bag. It brews a surprisingly clean cup for such an experimental process, with a really distinct jammy finish that lasts.

Elizabeth ★★★★★

I usually go for washed coffees, but this co-ferment is a game changer with that bright, jammy note cutting through the rich body. It’s incredibly smooth, and the flavor lingers nicely even after the cup cools. Definitely one of the more unique bags I’ve brewed lately.

Ella ★★★★★

The blackberry co-fermentation gives this coffee a tartness that cuts through the milk perfectly. I brewed it as a pour-over and got a lingering wine-like finish that’s totally new to me. A 5-star find for anyone bored with standard single origins.

Richard H. ★★★★★

I’ve never tasted a coffee that actually smells like fresh blackberries before opening the bag—this one delivers. The fermentation process gives it a subtle, wine-like acidity that’s surprisingly smooth. Definitely a short-lived treat since it’s limited.

Adam ★★★★★

The blackberry flavor is incredibly vibrant but not artificial at all, it smells like fresh jam in the bag. Brewed it as a pour-over and got a really clean, sweet cup with none of the funk you sometimes get with co-ferments. Definitely grabbing another bag if they restock.

Benjamin W. ★★★★★

Finally got to try this blackberry co-ferment, and the fruit-forward acidity is unlike anything I've brewed before—bright and clean without being sour. The fermentation process really lets the blackberry notes come through naturally in the cup. Definitely grabbing more if it comes back.

Jacob ★★★★☆

I’m still halfway through the bag, but the blackberry co-ferment adds a fruity brightness that’s really unique without overpowering the coffee itself. It brews smooth with no bitterness, even when I let it steep a bit longer than usual.

Claire ★★★☆☆

I was curious about the blackberry co-ferment process, and the fruit flavor does come through, though it’s a bit more subtle than I expected. The beans felt a bit unevenly roasted, as a few were darker than the rest. It’s a decent cup for the price, but I’ve had more consistent single-origin coffees before.
