BOOSTER 63Precision Flow Tool for Immersion & Press BrewingBOOSTER 63 is a precision-engineered stainless steel mesh disc designed to increase extraction strength, optimize drawdown flow, and deliver stable, repeatable brews in immersion and press brewing systems.Positioned between the filter and the brewer, BOOSTER 63 increases contact points under the coffee bed, improving flow dynamics and extraction efficiency. The result is faster drawdowns, higher extractions without channeling, and smoother, richer, and sweeter cups—even when using finer grind sizes or pushing extraction yields.By simply placing BOOSTER 63 beneath your paper filter, you can unlock greater consistency and clarity without changing your brewer. Compatibility:- Immersion and press brewing systems using 63 mm diameter filters Materials & Packaging:Stainless steel AISI 304 with food-grade gold platingIndividually packaged for protectionSustainable FSC-certified paper packaging
