SCA Certified Home Brewer. One Of Roughly 31 In The World.
Most drip coffee makers heat water to 175 to 185°F, which is significantly below the temperature needed to fully extract specialty coffee. The result is flat, under-extracted, sour coffee, no matter how good the beans are.
The Ratio Six holds water between 197 and 205°F throughout the entire brew cycle. It delivers the SCA Golden Cup standard, the same coffee-to-water ratio and extraction yield professional baristas target. The Specialty Coffee Association tests every certified brewer in the lab. Only about 31 home brewers in the world have earned the mark.
For a veteran owned coffee company that scores every bean at 85+ on the SCA scale, this is not just another brewer on the shelf. It is the brewer built to the same standard as our coffee.
Why You Will Love It
Push-Button Perfection
Automates bloom, brew, and flow for café-quality pour-over without needing a Ph.D. in extraction. The bloom cycle releases CO2 from freshly roasted beans before full extraction begins. The same technique specialty baristas use when hand-pouring, dialed in automatically.
Built To Outlast Turbulence
Precision-stamped stainless steel, handblown borosilicate glass water lines, BPA-free copolymers. Built for daily flight. Backed by a 5-year manufacturer warranty.
Precision Engineering
Delivers 200°F water through a wide stainless steel showerhead with 24 holes for even saturation across the entire coffee bed. Reduces channeling. Promotes uniform extraction. Tastes the difference in your cup.
Generous Capacity
Brews up to 40 oz (eight 5oz cups). Perfect for your hangar crew or a solo caffeine sortie. The auto-sealing thermal carafe holds brewing temperature for at least an hour with no warming plate needed.
Quiet, Sleek, Compact
Low-profile, minimalist design with a performance engine under the hood. Fits under cabinets. Flies above expectations. Available in Matte Black and White.
Series 2 Upgrades
- Redesigned Thermal Carafe: Features a more pronounced spout for a better pour and a wide opening for easy cleaning. No moving parts.
- Updated Water Tank Markings: Now correlate with water volume in the tank for more accurate brewing measurements.

Ratio Six FAQ
Is the Ratio Six really worth the price?
For anyone drinking specialty grade coffee at home, yes. The Ratio Six is one of roughly 31 SCA Certified Home Brewers in the world. It holds water at 197 to 205°F, the temperature range required to properly extract specialty coffee. Most $100 to $200 drip machines heat water to 175 to 185°F, which under-extracts your beans. If you spend $5 to $6 per day at a coffee shop, the Ratio Six pays for itself in about two months.
What is the SCA Certified Home Brewer mark?
The Specialty Coffee Association tests home brewers in the lab against strict standards for water temperature, brew time, and extraction yield. Only about 31 brewers in the world have earned the certification. The Ratio Six is one of them. It is the most reliable independent quality credential a home brewer can carry.
What grind size and ratio should I use?
Start with a medium grind (similar to granulated sugar) and a 1:16 ratio. For a full 40oz carafe, that is about 70 grams of coffee. Adjust slightly to taste. Coarser for a lighter cup, finer for more body. For the complete breakdown, read our coffee brewing guide.
What's the difference between Series 1 and Series 2?
The Series 2 features an updated thermal carafe with no moving parts, a more pronounced spout for cleaner pouring, a wider opening for easier cleaning, updated water tank markings, and an enhanced heat shield around the showerhead for hotter extraction. The Series 2 carafe is compatible with the original Series 1 filter basket.
What is the warranty?
Ratio backs the Six with a 5-year manufacturer warranty covering defects in materials and workmanship. We help facilitate warranty claims if any issues come up.
How long does the thermal carafe keep coffee hot?
The auto-sealing thermal carafe holds brewing temperature for at least an hour and stays pleasantly warm for several hours beyond that. No warming plate means no scorched, stale coffee sitting on a hot burner.
Can I use it with a Chemex?
Yes. Remove the included filter basket and brew directly into a Chemex carafe positioned underneath. You get the Chemex's clean, paper-filtered cup with the Ratio Six's precise temperature and bloom control.
Does it ship from Texas?
Yes. Orders ship from our roastery in Rockwall, Texas. You are buying from a veteran owned small business, not a holding company warehouse.
Upgrade Your Mornings. Automate Your Precision.
The SCA Certified Ratio Six paired with 85+ SCA scored beans from a 100% Disabled Army Aviation Veteran roastery in Rockwall, Texas. The whole standard, end to end.
