Slow drip cold brew is typically associated with elaborate, expensive setups. The Puck Puck changes that equation entirely — it is a simple device that sits on top of your AeroPress and turns it into a slow drip cold brew maker, all for around 30 pounds ($35). That is a fraction of the cost of a larger cold drip tower. But is it any good?
What Is in the Box
The Puck Puck kit includes:
- The Puck Puck device itself — essentially a precision valve
- A splash filter that clips into the bottom and sits inside your AeroPress, dispersing water evenly across the coffee grounds instead of letting it drip into the same spot
- A 500ml water vessel with a lid, which screws into the top of the Puck Puck
- A small instruction guide
The vessel features a universal screw system, so you can use any compatible mineral water bottle — just cut the top off and screw it in. This makes the whole setup genuinely portable.
The Drip Calibration App
Yes, the Puck Puck comes with an app. Load it up, tap the screen each time a drop falls, and it tells you whether your drip rate is correct or whether you need to adjust the valve — screw tighter to slow down, unscrew to speed up. It is straightforward and surprisingly satisfying to dial in. If that is not peak coffee geekery, nothing is.
How to Brew
The setup is beautifully simple — everything stacks on top of everything else.
Step 1: Place a jug or container at the bottom. Make sure it can hold at least 400ml of water plus the volume of melting ice — we learned this the hard way when the first attempt overflowed.
Step 2: Add a paper filter to your AeroPress filter cap. Fill the lower chamber with 38 grams of medium-ground coffee.
Step 3: Place the splash filter on top of the grounds.
Step 4: Slide the Puck Puck onto the AeroPress, then attach the vessel on top.
Step 5: Add 100 grams of ice (roughly one standard ice cube tray) and 400ml of water to the vessel. Pop the lid on.
Step 6: Slowly unscrew the top portion of the Puck Puck (leaving the bottom attached to the AeroPress) until water begins dripping through. Use the app to calibrate to approximately 50-60 drops per minute.
Step 7: Walk away for about two and a half to three hours.
If you are using slightly older coffee grounds, you can pre-wet them — just deduct that amount of water from what you add to the vessel.
The Results
After about three hours, the chamber empties out and you are left with a beautifully dark cold brew. The coffee we made with Taylor’s Lazy Sunday (a lighter, three-roses roast) produced something genuinely impressive.
The flavor: dark chocolate and beautiful roast notes, but noticeably sweeter than if you had brewed the same coffee hot. The cold water extraction creates a smooth, creamy mouthfeel — crisp and clean, but absolutely full of flavor. No concerns about the brew being watered down or thin. It was full-bodied, strong, and refreshing.
You can enjoy it straight, mix it with milk, pour it over ice for a longer drink, or even use it in a cocktail like an espresso martini. It also stores in the fridge for around two weeks before the flavor starts to fade, so you can batch-brew and have excellent coffee ready every morning without any fuss.
Cleanup and Verdict
Cleanup is the one area where the Puck Puck is slightly less convenient than a standard AeroPress brew — you are dealing with a few more parts. But it is still minimal: dump the grounds, give everything a rinse, and you are done.
For $35, the Puck Puck is a fantastic nerdy coffee accessory. It is easy to use, produces genuinely excellent cold brew, and works with equipment you probably already own. If you are looking for a fun, affordable way to make beautiful slow drip cold brew, this one is easy to recommend.
