Orea Regulator Pack – #2 & #4

Same brewer. Two more speeds. These are two silicone inserts that sit in the base of your O1 or O2 and cap how fast it drains. A lower maximum flow sets a minimum contact time, so you can grind coarser and still hit your brew time. That helps with very soluble processed coffees, very light roasts and darker roasts. Neither one is slow. The #4 is medium and the #2 is the slowest. With the same grind and recipe, going from Orea's fastest regulator to the slowest adds 15–30 seconds of contact time, and raises TDS (strength) with it. In the pack #2 Regulator: dark grey, slowest #4 Regulator: black, medium Specs Fits: Orea O1 (Tritan and Steel), O2, and Orea's older open-bottom porcelain and glass brewers Material: food-grade silicone, BPA-free and certified food safe (EU and US FDA) Made in Taiwan Also see: Orea Switch Adapter – #8 Regulator, the fastest of the three.
