A $180 coffee maker should not produce bad tasting cup of coffee, so my Keurig B70 Single Cup Coffee Brewer has been pretty disappointing.

The burnt-rubber and chemical laden taste was so overwhelming that I couldn’t even finish a cup. Granted, any new coffee maker is expected to have a plastic taste for the first few cups, but it’s usually gone after a few brews to break it in. The horrible taste did not go away no matter how many cycles of coffee I went through.

I started researching and looking for other people that have had the same experience, and sure enough, many others in an Amazon discussion are tasting the same thing.

The problem seems to be coming from the reservoir and the type of plastic it’s made out of. Apparently the plastic isn’t capable of handling the high temperatures and is leeching into the water. Interestingly, some people aren’t able to taste it at all, so this may suggest that Keurig is using multiple manufacturers and materials. It’s also possible that some may have a genetic predisposition to tasting the chemicals in question. That is still up in the air, as you’ll see in the Amazon reviews.

Keurig seems to be aware of the issue and they are reportedly helpful in attempting to fix the problem. If you contact them, they will send you a new reservoir if you are still experiencing problems after cycling the water through multiple times.

If you don’t want to go through that hassle, you can also try exchanging it where you bought it and testing a new one. They claim the newer reservoir is made of a more optimal material. This begs the question – why are they still selling brewers with subpar materials in the first place? The problem is ongoing for over a year now, so you’d think they’d fix the problem already. For a $180 coffee maker, funky tasting coffee is not cool, and going through all this trouble is definitely not cool.

Try these steps to get rid of the nasty Keurig brewer taste

  1. Remove the reservoir from the Keurig, and fill it with hot water & dish soap.
  2. Let it soak for 30 minutes.
  3. Take a sponge to it and scrub it out thoroughly.
  4. Rinse the reservoir.
  5. Fill it up again with just water and add a 1/2 cup of white distilled vinegar.
  6. Hook it back up to the Keurig.
  7. Cycle through several cups of just water/vinegar until it’s empty (use the largest cup size to speed this up).
  8. Fill it up again with just water (no vinegar) and cycle through the reservoir again.
  9. Repeat step 8 again until the funky taste is gone. It should only take a couple cycles.


If you still have a plastic or rubbery taste in your coffee after all that, you should contact Keurig and have them send you a new reservoir, or just get your money back if you still can. You can call their customer service at 1 (866) 901-2739, or visit their support page.

Please leave comments and let me know if this works for you, or if you have any better methods of cleaning it out! I’m also interested to know if the newer 2.0 brewers have the same issues, so if you have experience with one of those beasts, feel free to comment below.


I took some advice from the comments below and cleaned out my k-cup holder after I started tasting the plastic again after a couple days. It wasn’t as strong, but it was definitely still there. After soaking the holder in vinegar and washing it thoroughly, the taste seemed to be gone again for a little while, but then it came back again after a couple of days. I returned the Keurig for a full refund and have no plans for wasting my money on another one. I’ve got better things to do with my time.

I’ve since been exploring other coffee makers and methods for brewing, and eventually came upon a device called an Aeropress that is working amazingly well for me. It’s not an automatic brewer, so it takes a little bit more work, but it’s definitely worth it. Plus, it’s only $30, as opposed to $180! I’ll probably write more about it and other Keurig alternatives in the near future.
