“I have a December Dripper which is like a metal Kalita Wave but with adjustable flow rate.”
“I use the December dripper for this occasionally, it's a bit leaky and is dripping super slowly but good enough so I don't have to buy a yet another gadget.”
“I got a December Dripper that I nearly never brew with. It's just a less-useful, more complicated, Clever that's hard to handle while in use. Add in that I have to buy either grocer flat-bottom or Wave filters, it's just more work to make shine than it's worth.”
“The December Dripper acts much like the Kalita Wave 185. Tbh I never really got into playing with the number of holes to open when pouring. I've always kept them all opened. I had some good results closing them all during bloom though. I so wish the thing had a handle though the silicon glove doesnr work the best.”
“For high altitude coffee, I can get insane floral notes in the December dripper.”
“$58 is a lot to ask for a "variable flow" pour-over rig that is not even necessary.”
“Lost me at teflon”
“In the December Dripper I have been able to successfully brew batch sizes ranging from 10g on up to 60g of coffee; that is to say, a single ~150ml cup on up to ~1000ml to share.”
“I don't regret the purchase but i don't use it that much: mountain dripper, december dripper, cezve”
“my hands down go to is the Kalita Wave 185 or the December Dripper (Korean Kalita variation with adjustable drip settings).”
“It’s completely solved the frustration I used to have with the Stagg X and December Dripper. The flow rate quickens significantly.”
“I use the December Dripper wide open, and if you look at that design, you will notice it too suffers from the filter sitting directly on the holes.”
“I'm a regular December Dripper user. It's a really nice method to mess around with coarser grinds. It takes some practice though: my first few attempts at getting a well extracted cup with coarser grinds -- even with adjusting the settings -- was leading to some pretty weak cups. Still, when you get it right, the December Dripper can create some really uniq”
“I got a December Dripper about a year ago and I have very mixed feelings. grinding on an EK or a Breville Smart Grinder I usually experience a very slow drip rate, even with the valve fully open (4’12” compared to 3’40” on a kalita or 3’00” on a 2 cup v60). It also had a lot of issues when I first got it with leaking out the side, especially when it was full”
“it leaks a little bit when closed and the results are pretty close to a standard wave”
“the best cup I made of their East Timor coffee (a very different coffee, but still super light with low solubility) was one where I ground pretty fine and used the December Dripper (a flat-bottom dripper where you can close the bottom opening kind of like the Hario Switch)”
“I'm still waiting on the gasket fix for my 2nd December Dripper. 1st one had the leaking problem and I tried the "hammer fix". It still leaked. They sent a new one. On the 1st try, it worked fine. On the 2nd? Coffee everywhere.”
“I also have a December dripper that replaced my V60, but I simply haven't bought the right sized filters and I'm spoiled to how easy it is to use my Clever.”
“I've got no issues using my Kalita or December drippers.”
“The December Dripper is awesome! You can do some really interesting super course slow drip brews. Make sure to take an Allen wrench and clean the inside Teflon if you do get one. However I found my best brews came off of a V60 and now pretty much am exclusive to it (my2 cents)”
“Looks like this might be another December Dripper for me. Where I use it for a few weeks then it's a setpiece lol.”
“2 weeks ago I had coffee brewed with december dripper in Andante cafe in Helsinki and was left unimpressed.”
“I’ve been using a December dripper for this style of brewing and really enjoy it. I grind very coarsely so I typically keep the valve closed for the bloom to saturate. The shallow, flat bed makes it easier to pour evenly while minimizing agitation. Probably my favorite pour overs.”
“My top 2 drippers are the Orea Narrow (I own the v3 but the v4 has a narrow option) and the December Dripper. December Dripper functions similar to a switch but can vary the flow better than the switch (which is open vs close). They both work it Kalita 185 filters and are really nice!”

“I use a December Dripper which is basically a Kalita Wave 185 but with adjustable flow.”
“I'm trying their \*April brewer recipes on my December Dripper Bottomless, and while I've yet to completely dial in, I can happily use 27-28 clicks and get decent drawdown times.”
“My December Dripper also drips ever so slightly when it is closed. I am not sure if this is the side leak issue or not, but I never expected it to seal completely. I feel like it is within tolerances.”
“I can treat it like how I use my December Dripper. I close it off at the bloom. Then, open it and pulse pour normally. Shutting off the drips at the bloom makes it more efficient; I can use less water to wet all the grinds.”
“I haven't yet seen a clear advantage over the wave”
