Coffee brewing accessories

A valved cap that replaces the AeroPress stock cap to stop dripping, hold water for longer steeps, or build back-pressure for espresso-style shots. Common models: AeroPress Flow Control Filter Cap, Fellow Prismo, Joe Presso (for a true espresso shot, the Prismo’s pressure valve).

DragonFly's separate switch base for the Tri-Spin FS flat-bottom dripper. A knob (O open / X close) holds water in the dripper for immersion or releases it for drawdown. Sold apart from the dripper, which on its own has no valve.

Recommended DragonFly Tri-Spin FS Flat Transit Base

The Hario Switch's valved base, used underneath other drippers (Hario V60 NEO, Sibarist UFO) to add stop-and-go immersion. Here it is required as an add-on base, not as the standalone brewer.

Recommended Hario Switch

Mazelab's separate "Solo Spin" switch base, adding an open/close valve for immersion phases. It fits both the original Solo and the larger Solo Tritan; sold apart, each dripper on its own is a valveless fast-flow brewer.

Recommended Mazelab Solo Spin

A food-safe silicone flow regulator that drops into the open base of OREA O1/O2 (and older open-bottom) brewers. The #2 (dark grey) is the slowest: it caps the maximum flow rate to enforce a longer minimum contact time, so you can grind coarser and still hit your brew time.

Recommended OREA #2 Regulator

A food-safe silicone flow regulator for the open base of OREA O1/O2 (and older open-bottom) brewers. The #4 (black) is the medium setting: its capped flow rate sits between the #2 and #8, adding contact time without going as slow as the #2.

Recommended OREA #4 Regulator

A food-safe silicone flow regulator for the open base of OREA O1/O2 (and older open-bottom) brewers. The #8 (orange) is the fastest of the set. It also fits a Hario Switch base, turning a flat-bottom brewer into a stop-and-go immersion setup with a quick drawdown once you release the valve.

Recommended OREA #8 Switch Regulator

A reusable chilling sphere rested on the slurry to drop the brew temperature during extraction (flash-style cooling).

Recommended Paragon Cold Brew Sphere

A frother, steam wand, or whisk to aerate and foam liquids — milk for milk drinks, or egg yolk and cream toppings (Vietnamese egg / salt coffee).

The Kruve Sifter is a set of stackable sieves that sort ground coffee by particle size. Sifting out the finest fines and the largest boulders narrows the grind distribution, so more of the bed extracts at the same rate — a cleaner, more even, more repeatable cup. Kruve is the best-known coffee sifter, with interchangeable screens across a range of micron sizes.

Recommended Kruve Sifter

A handheld dispersion screen you pour onto; it softens the water stream so it does not agitate or bore into the coffee bed.

Recommended Melodrip

A moulding tool that seats a flat paper filter tightly against the walls of OREA's narrow flat-bottom brewers (V2, V3, V4 Narrow, O1, and the glass/porcelain models), so the paper hugs the walls and forms a low-bypass bed — forcing water through the coffee instead of around it, for higher and more consistent extraction. You press it in to shape the paper, then pull it out before drawdown; it does not restrict flow. Pair with OREA flat paper.

Recommended OREA Neo Negotiator

A cluster of fine needles used to stir and de-clump the coffee bed (Weiss Distribution Technique) for even saturation.
