Thanks to a clever and simple innovation, the December Dripper is so much more than another pour-over device. The adjustable flow rate and a flat-bottom design will add a good deal of versatility to your brewing setup.

Designed by Nick Cho and Youngmin Lee, the December Dripper offers a very unique, but simple addition to classic pour-over brewing: control over the flow rate as the brew bed drains. With a simple turn of the dripper's base, you can select from three different flow rates, or shut off the flow almost entirely. It may not sound like much, but that extra level of control can add a good deal of versatility to a dripper. While some pour-over devices might be more restrictive in their batch sizes, the December Dripper can adapt to a much wider range of brewing conditions. You can just as easily brew a single small cup of coffee - using a lower flow setting - as you can brew a full liter-sized batch - with the flow set to max. You can even adjust flow rate mid-brew, so you can limit the flow for your bloom and first pour to allow for more contact and thorough extraction, then open it up for faster flow for the latter half of the brew to allow better washing of the grinds and give yourself more control over total brew time. The possibilities here are myriad, and that's really exciting for such a simple brewing device.

The December Dripper is made in South Korea from stainless steel and PTFE, with a silicone sleeve. All the parts are dishwasher safe, and the base and brewer can be detached by removing the screw using an allen wrench (not included).

Flow rate stages:

  • Stage 0 is when the flow rate is "closed." There are no holes open in this stage, however there may be a trickle of liquid out of the dripper. This is simply because of slight variations in manufacturing. Stage 0 may be useful for extended blooms, immersion-style brewing, extending contact time, or brewing iced coffee.
  • Stage 1 is the lowest flow rate, optimized for small brews of 10-12 fl oz. We have enjoyed 8 fl oz brews with this setting as well, using Stage 0 for an extended 45-50 second bloom phase.
  • Stage 2 is optimized for medium brews of 14-16 fl oz. This setting is about 50% slower than a steel 185 Kalita Wave, in our experience.
  • Stage 3 is the fastest flow rate, optimized for large brews over 16 fl oz. We've found that this setting is about 30% faster than a steel 185 Kalita Wave. We have also brewed full 1 liter batches on this setting with good results, but keep in mind that large doses like this are pushing the limits of the dripper's capacity.
