The O2 is OREA's bigger sibling to the popular O1, a unibody flat bottom brewer built for those who brew larger volumes, whether that's a bigger single serve or brewing for two. It shares the O1's original open bottom design, which lets the paper filter bend naturally through the middle for a more central water flow and a candy-like acidity with balance, sweetness and body intact.

The Darth Black is the O2's special launch edition, a deep, semi-transparent black finish with a nod to OREA's original V3 Glossy Black, but with heavier pigmentation while still allowing a view inside the brewer.

Each brewer is moulded from a single piece of genuine Eastman Tritan plastic (BPA-free, food-safe, made in the USA), manufactured by a family-run boutique factory in Taiwan. No moving parts, no injection, and no flow marks. Just a clean, simple, easy-to-clean design.

Features

Unibody, single-piece construction with no moving parts
Original OPEN bottom design for a more conical flow and central water path through the coffee bed
Compatible with OREA Regulators (sold separately) for immersion and hybrid brewing styles, including the Hario Switch base
Best suited to lighter, more tea-like bodied brews; for thicker body, OREA recommends their Z1 brewers

Filter compatibility

Wave: Traditional 185 wave size, or OREA's large wave paper. Wave filters allow more bypass and airflow for a narrower bed and a less concentrated brew.
Flat: Large 185 OREA flat filters, or large 185 Sibarist FAST flat filters (labelled O2/V4 filters). Flat filters reduce bypass for a wider, shallower bed and a juicier, fuller-bodied cup.
