LACC customers rate us 4.9 out of 5 across 3,000+ verified reviews. The Certification That Sets It Apart Most drip machines heat water to 175 to 185°F. That is well below the range specialty coffee needs, so the cup comes out flat, sour, and thin no matter how good the beans were. It is the single most common reason great coffee tastes disappointing at home. The Ratio Six holds 197 to 205°F from first drop to last and hits the SCA Golden Cup standard for coffee-to-water ratio and extraction yield. The Specialty Coffee Association tests every certified brewer in a lab. Only about 31 home brewers in the world have earned the mark. We roast nothing under 85 on the SCA scale. This is the brewer built to the same standard as the coffee. Why It's Different Every part of the machine has a job. Automatic bloom releases CO2 from freshly roasted beans before full extraction starts, the same first step a barista does by hand. 24-hole stainless showerhead saturates the entire coffee bed evenly, which reduces channeling and keeps extraction uniform. 1400W die-cast aluminum heating element holds brew temperature instead of drifting down mid-cycle. Auto-sealing thermal carafe holds brewing temperature for at least an hour with no hot plate cooking the coffee. Materials that last, precision-stamped stainless steel, handblown borosilicate glass water lines, and BPA-free copolymers, backed for five years. Low-profile and quiet. It fits under a cabinet and does not sound like a shop vac at 5am. Series 2 Upgrades Redesigned thermal carafe with a more pronounced spout for a cleaner pour, a wide opening for easy cleaning, and no moving parts. Updated water tank markings that correlate to actual brew volume for more accurate dosing. Enhanced heat shield around the showerhead, which raises extraction temperature and puts a hotter cup in the carafe. The Series 2 carafe is compatible with the original Series 1 filter basket.

If you drink specialty grade coffee at home, yes. It is one of roughly 31 SCA Certified Home Brewers in the world, and it holds the temperature range that specialty coffee actually needs. A $100 to $200 drip machine brews at 175 to 185°F and under-extracts everything you put in it. At $5 to $6 a day for shop coffee, the Ratio Six pays for itself in about two months. What is the SCA Certified Home Brewer mark? The Specialty Coffee Association lab-tests home brewers against strict standards for water temperature, brew time, and extraction yield. Only about 31 brewers in the world have earned it. It is the most reliable independent quality credential a home brewer can carry. What grind and ratio should I use? Start at a medium grind and a 1:16 ratio, about 70g of coffee for a full 40oz carafe, then adjust to taste. What changed in Series 2? A redesigned thermal carafe with no moving parts, a better spout, a wider opening for cleaning, updated tank markings, and an enhanced heat shield for a hotter cup. The Series 2 carafe works with the Series 1 filter basket. How long does the carafe stay hot? The auto-sealing thermal carafe holds brewing temperature for at least an hour and stays pleasantly warm for several hours after. No warming plate means no scorched, stale coffee. Can I brew into a Chemex? Yes. Remove the included filter basket and brew directly into a Chemex positioned underneath. You get the Chemex cup with the Ratio Six's temperature and bloom control. What is the warranty? Ratio covers the Six for five years against defects in materials and workmanship, and we help facilitate any claim. Where does it ship from? The brewer ships direct from Ratio's warehouse, so it reaches you without a second leg through our shop. Any coffee you add to the order is air-roasted and shipped from our roastery in Rockwall, Texas. Same Standard, End To End We hold every bean to 85 or higher before we roast it. Ratio holds every cycle to 197 to 205°F before it pours. Put the two together and the guesswork disappears from your morning. 100% disabled veteran-owned. Ten percent of every purchase supports veteran and aviation causes. Never bitter. Always better. Be relentless.
