Mariam Erin Unveils Binocular Dripper in Dubai: Dual-Cone Wet Blending for Competition

Mariam Erin introduced the Binocular Dripper at World of Coffee Dubai, presenting a new tool aimed at competition baristas, experimenters, and small cafés. The device is a dual-cone manual pourover that lets operators brew two small doses independently and merge the extractions into a single cup, a technique Erin describes as 'wet blending'.

The dripper accepts standard V60-02 filter papers in each cone and is designed around 6-12 g doses per cone. Each side can run distinct grind sizes, doses, or pour patterns while the combined flow meets at a shared outlet into a server, producing one freshly blended cup. That configuration gives brewers fine-grained control over extraction dynamics and cup composition without needing to mix brewed coffees post-extraction.

Mariam Erin developed the Binocular Dripper with input from competition practice and retail testing, and retailer Brewing Gadgets positioned the product specifically for competition use, experimentation and small-batch café service. Sets began shipping in Asia with delivery dates listed from Jan. 18, 2026, making the brewer available to early adopters in the region soon after the Dubai unveiling on Jan. 21, 2026.

For judges and competitors, the Binocular Dripper changes how judges will see recipe development. Instead of blending roasted lots before brewing or mixing cups after extraction, competitors can present a single cup that combines two parallel extractions with different variables - for example a fine, fast extraction on one cone and a coarser, slower extraction on the other - to balance acidity, body and sweetness in controlled proportions. The dripper also opens straightforward experiments in roast pairing, single-origin blending and micro-lot research, because each cone can be treated as its own extraction channel.

For cafés serving limited volumes or experimental menus, the dripper offers a compact way to produce blended-tasting cups without setting up multiple brewers. Verify server size and flow rate when adapting existing service procedures, and confirm stock of V60-02 papers to ensure compatibility. Expect a learning curve; synchronizing pour patterns and dosing will require practice to achieve repeatability for service or scoring.

The Binocular Dripper is both a specialty tool and a conversation starter - two cones, one cup, and a new vocabulary for extraction play. Watch for units to appear in competition lineups and café bars as brewers test wet blending protocols and publish recipes. If you plan to experiment, calibrate grind size and dose per cone in small increments and record timing so you can reproduce successful blends.
