Ratio Eight Series 2 Coffee Machine – Automatic Drip Coffee Maker with Dual Brew Recipes, 40 oz Capacity, Handblown Glass Carafe, Solid Wood Accents

Product Overview

Using the RatioEight Series 2 feels like having a skilled barista at home. The brewing process begins by selecting either the full-batch or half-batch recipe, each calibrated to deliver optimal extraction and rich flavor. The machine heats water to the precise temperature and showers the coffee grounds evenly, mimicking the pour-over technique. The result is a clean, aromatic cup with bright acidity and full body, without bitterness. The materials play a key role: the stainless steel and glass hot water path prevents any metallic or plastic taste, while the handblown borosilicate glass carafe keeps the coffee warm without affecting flavor. The solid hardwood accents add warmth and a natural touch, complementing modern or traditional kitchens. At 14 pounds, the machine is robust and stable. Dimensions are 13.5 inches deep, 9.75 inches wide, and 14.25 inches tall, fitting under most cabinets. The included brew basket and carafe are the primary components; it uses standard paper pour-over filters (not included) for a clean brew. Care and maintenance involve washing the carafe and brew basket after each use and wiping the hardwood accents with a damp cloth. The machine is not compatible with smart home systems, so it's a standalone unit. Portability is minimal due to weight, but it's designed for a permanent spot. Overall, the RatioEight Series 2 offers a premium experience for those who appreciate the art of pour-over but want the convenience of automation.

Build & Materials

The RatioEight Series 2 is built with an emphasis on purity and aesthetics. The water path consists of stainless steel and glass, materials chosen for their inert properties that do not impart unwanted flavors into the coffee. The handblown borosilicate glass carafe is both heat-resistant and elegant, allowing the user to watch the coffee flow. Solid hardwood accents provide a warm contrast to the matte black body. The brew basket is also made from high-quality materials and is designed to accommodate standard paper filters.

Caring for the machine is straightforward. The carafe and brew basket are removable and should be hand-washed with mild soap. The hardwood accents should be cleaned with a damp cloth and dried immediately to prevent damage. The machine's weight of 14 pounds and non-slip base ensure stability during brewing. Overall, the construction reflects a commitment to craftsmanship and longevity, though the price reflects the premium materials.

Shot Quality

The RatioEight Series 2 delivers consistent brew quality in terms of temperature stability and extraction. The dual brew recipes are calibrated to maintain the same ratio of coffee to water whether brewing a full or half batch. Users report that the coffee tastes clean, balanced, and free of bitterness, thanks to the precise water temperature and distribution. The stainless steel and glass water path ensures that the water stays hot throughout the brewing cycle, contributing to full extraction.

One trade-off is that the glass carafe does not keep coffee hot as long as a thermal carafe would, so coffee is best consumed soon after brewing. However, the clarity of the carafe allows visual monitoring. Additionally, the machine does not include a built-in grinder, so users need a separate grinder for freshly ground coffee. Overall, for those who prioritize brew quality over convenience features like programmability, the RatioEight Series 2 performs admirably.
