What customers say
Users overwhelmingly praise the Acaia Pearl Model S for its exceptional accuracy and rapid response time, essential for precise coffee brewing. Its premium build quality is consistently highlighted, contributing to a high perceived value among serious enthusiasts and professionals. A key feature is the real time flow rate indicator, which greatly aids pour over technique refinement. Advanced functions like dedicated brewing modes and seamless Bluetooth connectivity enhance the data driven brewing experience. While the initial investment is significant, dedicated users agree the unparalleled precision, robust design, and advanced functionality fully justify the cost, making it a top tier instrument for perfecting coffee.
Know before you buy
The flow rate indicator allows you to monitor the speed of your pour in real-time. This helps you maintain a consistent stream, which is essential for achieving even extraction and balanced flavor in pour-over coffee.
While the Pearl Model S is designed primarily for pour-over brewing due to its size, it is accurate enough for espresso. However, its 160mm x 160mm footprint may be too large to fit comfortably on the drip tray of many compact espresso machines.
The Brewguide app provides step-by-step, interactive brewing recipes that sync directly with the scale. It guides you through specific pour weights and timing intervals, making it easier to replicate professional-level recipes.
The scale is built with a durable polycarbonate housing designed to withstand the occasional spill or splash common in a coffee brewing environment. However, it is not waterproof and should not be submerged in water.
You can set the scale to emit audible alerts at specific stages of your brew, such as when you reach a target weight or a specific time interval. This allows you to focus on your pouring technique without needing to stare at the display constantly.
No, the Pearl Model S features a built-in rechargeable battery. It charges conveniently via a USB-C port, eliminating the need for disposable batteries.
