The OREA O1 Steel Brewer is a compact flat-bottom brewer designed specifically for single-cup brewing, offering a fast, consistent, and highly controlled extraction. Built with high-grade double-wall stainless steel construction, it provides excellent thermal stability while remaining comfortable to handle during brewing. Compatible with flat-bottom filters (both flat and wave-style filters), the O1 Steel produces a balanced cup profile with vibrant acidity, sweetness, and clarity. Best suited for smaller brews around 10–18g doses, it’s a versatile brewer that combines precision, durability, and everyday usability in a minimal footprint.

A key feature of the O1 is its distinctive open-base geometry, which allows the filter to rest along the outer edges while gently curving inward at the center during brewing. This subtle shape changes how water travels through the coffee bed, promoting a quicker drawdown and a flow pattern that feels closer to a conical brewer despite the flat-bottom design. In the cup, this often translates to a brighter, more expressive acidity paired with clean sweetness and a balanced body.
