Detailed Brewing Information:
Profile A (For 12 oz or more): This brewing profile starts with a 100 ml bloom to pre-wet the coffee grounds, followed by a 30-second rest period to let the coffee bloom fully. After resting, water is dispensed in pulses at 5 ml per second for a total brew time of 2 minutes. Then, the Ratio Four switches to continuous water flow at the same rate until all water has been used. This method is perfect for larger batches of coffee, ensuring a balanced extraction.
Profile B (For less than 12 oz):
In Profile B, the Four dispenses 60 ml of water to bloom the grounds, followed by the same 30-second rest period. Pulse pouring starts after the bloom and continues at 5 ml per second for 2 minutes. The remaining water is then released in a continuous flow until the brewing is complete. This profile is tailored for smaller batches of coffee, less than 12 oz.
Activating Profile B:
You can activate an alternate bloom by pressing and holding the brew button. This changes the amount of water used during the bloom phase, offering more flexibility in your brewing.
Brewing Temperatures:
Standard Brewing Temperature: The Ratio Four maintains an average brew temperature of 201°F, which is ideal for extracting rich flavors from your coffee beans.
Alternate Brewing Temperature: If you’re using an alternate pour-over method, the brew temperature adjusts to 195°F for optimal performance.
Pulse Pouring Explained:
The Ratio Four’s unique pulse pouring feature is designed to evenly saturate the coffee grounds, breaking up the coffee crust that forms during the bloom phase. By alternating between pulse pouring and continuous flow, the Ratio Four can handle various batch sizes without requiring major adjustments to your grind size. For smaller batches (4–8 oz), you might need to adjust your grind, but for most brews, this system ensures great consistency.
