The best way to make cold brew coffee at home

Once you try our cotton cold brew coffee filter bag you won’t go back to fiddling around with paper filters, metal cylinder filters, and the like!

At Doppelgänger Goods (sister brand of Doppeltree) we stand out above the competition with our premium natural organic cotton cold brew coffee bags.

3 Reasons Why We're Better

1) BETTER MATERIALS

We globally source the best natural organic cotton to make our cold brew bags.

2) BETTER CONSTRUCTION

Our cold brew bags are hand-made and use a super fine weave (to all you aficionados out there the weave is about 90μ microns) so that only your delicious brew gets filtered out. 

If you’ve used nylon filter bags before you’re probably familiar with the “sludge” that inevitably ends up in your cup. 

With our cold brew coffee bag just filter once and you’re done; no need to filter two or three times to get rid of the sludge. Go ahead and wring every last drop of your cold brew out of the filter bag. Our bags won’t tear or fray.

3) EASIER TO USE

The last thing you want to do after you’re ready to enjoy your freshly made cold brew coffee or nut milk is to spend minutes trying to pry and loosen a wet cotton drawstring.

That’s why we decided to use a nylon drawstring instead, which makes untying the bag a fast and simple process.

We also made sure cleaning the bag is easy too. Just turn the cold brew coffee bag inside out, dump the grounds directly into the trash or compost bin, and then rinse it out under the faucet. Let it dry and you’re ready to go with another batch the next day.

☕️ THE BEST COLD BREW YOU'LL EVER TASTE
❛ OUR BAGS FILTER OUT ALL GROUNDS AND SLUDGE ❜

Compared to nylon, hemp, and other bag materials, the extra fine 90μ micron weave of our cold brew coffee filter bag ensures only filtered coffee leaves the bag, while grounds and sludge stay behind.


❛ OUR BAGS ARE MADE FROM 100% NATURAL ORGANIC COTTON ❜

Our medium 8in wide x 12in tall U-Shaped bag with a wide opening makes it easy to pour your coffee grounds into and out of the filter bag to avoid messes. Durable construction means you can squeeze out every last drop without tearing or ripping the filter. Use this bag in your own mason jars, pitchers, carafes, jugs, etc.


❛ OUR BAGS INCLUDE A HASSLE-FREE EASYOPEN DRAWSTRING ❜

Compared to other cotton cold brew coffee filter bags, our nylon drawstring makes it easy to open and close, even when wet.


❛ OUR BAGS ARE EASY TO CLEAN UP ❜

Just turn the cold brew bag inside out, dump spent grounds directly into the trash or compost bin, then rinse under the faucet and air dry.

📏WHAT SIZE BAG SHOULD I GET?

The majority of brews work well with a medium or large bag. The large bag gives you more flexibility to make larger brews half gallon or more, but may be harder to fit inside smaller containers.

Works great
Size: 6ft, Color: Silver
Just what I needed for my Dept 56 Christmas display. In past years, it's been a challenge to find enough open plugs for my display. This power strip completely solved that problem. I wish I had found this sooner.

Better than expected - big office cleanup
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
I got this power strip because it seemed like the most plausible one available, notwithstanding the reviews which particularly complained about it being prone to overheating. I certainly didn't want to burn down my home, so I tested it pretty thoroughly before I got anywhere near installing it. The power strip arrived exactly as claimed. It is indeed 45 inches long with sixteen outlets. The power cord is substantial-feeling, and feels like it's probably 14 AWG, or possibly #12 (Pic 1), and was the length I expected (6' in my case). The mounting brackets are sufficient to mount the power strip, but only at the ends, and they can't be concealed. This means that things don't end up as solid as one would like, and if you really care about aesthetics you'll end up being offended, but hey this is a power strip, and if you didn't have it the power cord mess would be way uglier. The outlets themselves are spaced out well enough that there's enough room to put in fairly wide wall wart transformers, but not those which have the plug pins configured such that the transformer has to point sideways. This means that if you want to be able to fill all of the slots, you can only put one of these in, and it has to go at the right-hand end. If you locate it on the left then it covers the switch. In my case, I filled the strip up completely, with one sideways transformer at the right hand end, and I still have many more plugs which won't go, but I've at least managed to improve my cable management a fair bit. Before I installed it, I tested it by boiling an electric kettle using the outlet which is the farthest from the switch (Pic 2). This is the most stressful way to test things, since is stresses all of the wiring and intermediate outlets before it even gets to the one I was using. The kettle draws 11.6 Amps, so about 1400W (though it's amps that actually matter). I then watched the thermal behaviour of the power strip as it worked. As can be seen the first thermograph, Pic 3, the power strip itself stayed cool, indeed barely above ambient. The power meter and power cord going to the kettle are on the right. Pic 4 shows a detail of the switch end of the power strip. The switch never heated to above 77F, which was again barely above ambient. Pic 5 shows a detail of the power meter shown in Pic 2. As can be easily seen, the power cord for the kettle warms up a bit, reaching 100F, but this is clearly the kettle's power cord and plug warming up, not the power strip itself. Pic 6 shows a detail of the unused outlets on the strip. These all warmed up a little, but never got over 83F. To me, this is negligible. As a result of this testing, I had no problems with going ahead and installing the power strip. I knew I'd be filling the power strip, but just adding up the devices I planned to plug in (two desktops, four screens, and numerous other devices), I knew that I wouldn't need more than about 4.5 amps, so I have at least 2.6X headroom. Pic 7 shows a part of the power strip as installed - I couldn't get far enough back to show all of it. Pic 8 is a thermograph of the same, with the power strip running across the middle of the picture. The how spots on the power strip are all transformers - clearly not very efficient, but not actually more than warm, and not the power strip's fault. By contrast, the really hot items visible are a DSL router on the far right, and a VOIP phone device lower on the right. Thus, I conclude that there's nothing untoward with the power strip. Lots of the devices I use are inefficient and/or run fairly hot, but if my house burns down, it doesn't look like it's going to be because of this power strip. All told, this product seems to be very good value for something that actually cleans up my life and has this many outlets. It exceeded my expectations, particularly since my expectations had been lowered by some of the other reviews. It would certainly have been better (for me) had it been longer and with more, and more widely-spaced, outlets, but I can't fault them for making what they made, and their claims seem to have been accurate. Still, the construction is not terribly sturdy and the mounting brackets should have been better thought out.

Plenty of Outlets and Solid Build
Size: 6ft, Color: Silver
I now have way more outlets than I’ll ever need—haha—but that’s not a bad problem to have! This power strip fits neatly behind my TV stand and feels very well made. The spacing between outlets is convenient for larger plugs, and it seems built to last. Overall, a high-quality and practical solution for managing multiple devices.

Good for dc power supplies
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
The AC outlets are very snug. I’m using this primarily for battery tenders and battery chargers; the outlets are spaced far enough apart to fit the dc power supplies and they stay in place even when mounted horizontally.

As good or better than most.

I was very happy with this item. It’s very heavy duty and appears to be something that will last me forever.
