Get a STRONGER Brew from your My Kcup

I love my Keurig Coffee Maker and if you are like me you probably enjoy experimenting with other non prepackaged coffee blends that aren't available in KCup form. That is where the "My KCup" accessory comes into play. For those unfamiliar, it allows one to brew a cup of their favorite coffee blends without needing to buy them in KCup form (if they are even available). Unfortunately the My KCup in my opinion brews a rather weak cup of coffee compared to it's pre-manufactured counterpart. Rest easy! I have found a fix that doesn't cost a dime! All you need is a "USED" KCup. Follow along. I have photos attached in order to make it easier to follow.

Step 2: Start Destruction

First we need to remove the foil lid of the used KCup using your scissors, knife or fingers. We don't need this to be perfect as we will be cutting the top off a bit when we are finished.

Step 3: Yuck

Once the foil top is removed we now have access to the used coffee grounds and filter. We want to remove these with our fingers and or a pair of scissors. Again this doesn't have to be perfect yet.

Step 5: Trim-it!

Using your scissors, cut the very top of the KCup Plastic shell about halfway down the little flat bump illustrated in the first picture all the way around removing the very top of the shell. you should be left with what is illustrated in 2nd and 3rd picture as shown next to the KCup we started with.  Also now is a good time to get that plastic shell good and clean.

Notice the hole in the bottom that was created by the Keurig machine when it was used. This whole is what is going to create more back pressure in the brewing process allowing the beans to seep more into the water causing a stronger brew.

Step 6: Mmm.... That fits nice!

Next we need to insert the plastic shell we just cut into the My KCup Body.  Notice in the pictures how it sits just below the top edge of the My KCup Body.  If yours protrudes above the top a bit pull it out and trim a little more off the top of the white plastic shell.  Once our fitting is satisfactory it is time to brew!

Step 7: Brew me a Cup of Joe!

This is how to assemble our new little modification. 

Insert the white plastic shell into the My KCup Body as we did in the test fit of the previous step. 

Then Fill your Basket with coffee grounds (I have found two mostly level tablespoons to be the optimal amount of grounds).

Place the lid on top and lock it in place and brew as usual.  Then "Enjoy your Stronger Brew!"

You can also play around with making your own holes in the bottom of an UNused KCup using a needle or pin to find the right setup for you.  But I find the used KCup hole to be as close to simulating an actual KCup brew.  I am not sure why Keurig's engineers didn't come to this conclusion on their own.  It stands to reason that a self filled KCup should brew in a similar way to an actual KCup.

A good K-cup to use is a hot chocolate one, because there aren't any grounds in them after the brewing process. That way you shouldn't have much to clean out of the inside.

Great Tip! There are a few different brands and flavors that are like that without even a filter I believe.

I experimented! I took a Kcup and sliced around the inside lip of the foil top and removed. I microwave a tiny bit of water then added it to the Kcup and steeped for 2+ minutes (don't overfill.) I put the lid only of a reusable Kcup on top. Inserted into my Keurig and brew! I use a wide mouthed cup as it is not a single stream of water. It was stronger. If the experts made this product better, we wouldn't have to do this. We should send a message and take them back to the store!

My guestion is whats the correct grind ? The keurig support was worthless when i asked ! Also ralphs and san francisco bay coffee have pods that work in keurig that arent plastic

From what I have read the best brew is slightly finer than a drip machine, but not as fine as an espresso grind. A french press uses a much more coarse grind than a drip machine. The finer grind allows for more flavor to be extracted during the faster brewing time. That's why the french press takes so long to properly extract the flavor and oils from the larger grind.

Thanks for the easy tip. Worked like a charm. I did find that non-Keurig brand K cups were too shallow for the filter. The keurig brand works perfect. And for the reuse of plastics paranoia, we breath and ingest more harmful pollutants driving down the highway or jogging in the park. Worry less and love more for a long happy life.

Uhh... once again, I'm finding a life hack where someone is using plastic and heat. Granted, K-Cups are SUPPOSED to be safe for use, but re-use? I don't know about that. If you compare this with milk or water jugs, they're indicated for a maximum of one reuse. After that they leech plastic into the liquid you put in them, and that is with cold liquids! I'm scared to think that K-Cups might leech plastic from the first use, but it might be that they leech after a second or third use. Who has info on the safety of reusing K-Cups? In the life hacker "culture" as it were, people seem to have a tendency to just grab stuff and off they go to do whatever, seemingly without any real knowledge of how safe or unsafe what they're doing is much of the time. Who has actually done homework on this? Take care and be safe!

According to this, there is research which demonstrates that even though the K-Cups are BPA free, there are many other chemicals that are even more bilogically active than BPA and are found in most plastics. The risks increase greatly when you apply heat. I will NOT be doing this! It simply isn't safe. As a matter of fact, I'm going to stop using the Keurig altogether. No matter what you do, using hot liquids in plastic isn't a good idea.

Interesting post. Thanks for the warning. I will research this further.

Thanks for the thorough instructions! I tried this method and it worked a little bit, however my coffee is still a little weak. Maybe I'll just stick to the regular k cups...I'm wasting this regular coffee.

Another non-messy way is to put the kcup in the machine to make the hole and don't make a cup of coffee. Then take it apart and just dump the dry coffee grounds out.

I tried this and it didn't work so well because my all in one k-cup
filter is a one piece number. (I already clean out used k-cups after I
buy them for recycling.) The reusable filter was too simply too large to fit inside. I did find that pre-ground coffee works better than grinding my own, even though the coffee looks the same. I think I'll stop being so lazy and go
back to the used k-cup and muslin filter and see if that works better. I hate that I have wasted so much very good coffee.

Great directions, but seems like a lot of extra work. An alternative way Instead would be to just peel off the top of the used K-Cup, and carefully rinse out the K-Cup leaving filter in, and taking care not to damage the filter. Then put in your favorite coffee, and cover the top with a doubled piece of tin foil (smooth it so it lays flat on the sides.) Plop is back in the regular K-Cup dispenser and enjoy a stronger cup of coffee. I tried it, and it works great. Question I have not answered yet is how many holes in the bottom of the plastic K-Cup will be too many before it stops working sufficiently . I'll keep doing it and let you all know.

Great instructable! I am intrigued by this approach, however, we have found the reusable filter to be a pain to clean. We purchased some of the paper filters but discovered the paper "lid" that is attached to them did not seem to work with the alternate cup holder due to the lack of a hole in the middle. I tried them again after making my own hole and that worked OK but was also a pain. I am thinking of trying this system but substituting the paper filter without the lid for the reusable filter to see what happens. Thanks for the info!

i am just stupid i guess.... but do you still use the filter??
Yeah, I too missed adding the "basket" in step 7. The coffee splattered and I ended up with coffee grounds in my coffee. Although, the coffee did taste better! Nonetheless, you are genius gojimi! I was seriously considering selling or writing Keurig due to MUCH disappointment with the coffee . . . and I've tried so many of the Kcups. Not impressed with any of them really. Question for you - what is your favorite kind of coffee?
gojimi (author)  SharryG3 years ago
Yes you still use the black plastic and metal mesh filter. Your coffee grounds go in there. You then place it inside the my kcup body with modified used kcup already inserted as shown in step 6 and 7. Enjoy!
Yes =)

Stupidity is doing something and knowing better, your simply ignorant, please don't feel that is an insult from me, I'm being literal. You literally don't know... so don't feel stupid!

Have a great day to!
a simple yes or no answer is more respectful
I think so, too.... thanks!

THANK YOU! This "fix" worked perfectly!
Thanks gojimi, this works very well.

Okay, so I have tried several methods of getting a stronger cup of coffee. Some I read here and some I've read other places. So far, my best experiment has been this: grind my favorite starbucks coffee in my coffee grinder making it a fine grind, reuse a k-cup after rinsing it out (the filter stays in). Pack the coffee tight into the K-cup then use a small double round of foil over top and sealed around edge. Brew and enjoy.... much better.

I am probably being too cynical but I wonder if the engineers knew how to get a stronger brew but got trumped by the marketers or top management. After all, if we users can't get a good tasting brew from the provided KCup method what do we do; we go back to the (high profit) cartridges offered by Keurig. Hmmmm

Great solution - and it doesn't cost a cent!!
@ notsodopey I see your point but I disagree. I believe it is poor design on the part of Keurig R&D. I think most of us here would simply leave the keurig if we couldn't get a satisfying cup of joe at a fair price.
In fact, the tip about lowering the gasket is something that shouldn't and wouldn't be necessary if Keurig gave a crap about it's target market.
Yup. Exactly what I was thinking!!!
I had the same thought @notsodopey... Excellent instructables @gojimi
My wife and I love our Keurigs. Se has ordered the new and improved My K-Cup which is supposed to address the weaker brew issue but I'll be keeping this Instructable in my back pocket in case it's just hype.

Thanks for this clever and easy tip! I've also been unsatisfied with the weak coffee from our Keurig. One time saver tip I can add: Not all K-cup containers are the same dimensions. The first used K-cup I cut was from a Twinings tea and discovered that the bottom of the tea container is more narrow than K-cup containers for coffee. The tea containers are too narrow at the bottom and don't allow the mesh filter to fit all the way inside. I took a glance at the other K-cups that we have right now and it seems that all of the tea containers are more narrow while coffee and hot chocolate are a bit wider. I hope that will save someone else some time and confusion. Thanks again!

Thank you, thank you, thank you!!! I'm drinking a cup of my own coffee now after retrofitting the K-Cup. I was ready to pull out my 12 cupper because of the frustration of seeming to be forced to use pre-filled cups. My coffee was so weak I couldn't even taste it! My coffee is now about 3 times stronger and delicious again! :)

Love this! I was really frustrated with brewing my own grinds! This works just right. Thanks

Found a neat product from mellita, called javajig. Found it at Walmart. Works much better than the k cup and comes with the filters.

I purchased a Keurig B31 Mini plus coffee maker, so i could brew Starbucks coffee, since Kraft [owners of Tassimo coffee makers], and Starbucks parted company.

I immediately noticed that the Keurig makes a noticeably weaker cup of coffee, because it just dumps hot water into the k-cup. [ The Tassimo design coffee disc forces the water through metered orifices in the disc for more complete saturation of the grounds].
After making two cups of coffee i opened the k-cup and noticed that the water makes a water hole straight through instead of being disributed through the entire surface of all the coffee grounds inside the cup. I like your idea and will keep it in mind. For now i am using Disposa K-cups with 2 paper filters instead of just one, in order to restrict the flow of liquid in an attempt to get more satuaration of the coffee inside the k-cup.Also it allows me to prefill 50 cups so i dont need to bother with messy grounds on a daily basis.
If im not satisfied with that, then i will attempt to use your idea. Thanks for posting.

Thank you for the great idea on how to create a stronger coffee!
I like to prepare the little paper cups ahead of time, then use as I need them. I found the miniature muffin pans hold the little paper cups filled with coffee real well, for now stored in a covered 9x13 baking pan.

Thank you so much. I'm amazed that people will take the time to teach these things. On verge of sending back coffee-maker, but now will try this.

STRONGER AND EASIER CLEANING Here is hoe I achieved stronger coffee. Buy the paper filters for the keurig. 50 for 4.99 ez fill. Tear the paper flap cover off the filter. Place in yor my cup reusable strainer. Fill with coffee - fine ground. Use as you would in the my cup holder. The paper filter allows you to add a bit more coffee but more importantly slows the brewing process because the coffee steeps a bit longer. Similar to pre infusion. I roast my own beans so aim very particular and tried all sorts of filter combos this works best for mt taste which is strong coffee but not a dark roast To lclead just pop the paper filter out and discard much like a traditional drip filter
