Question: If you want stronger coffee, can you just put in 6 oz of water instead of 8-9? Does that work, and can you get the full extraction that way?
Document: Then leave some head space between the coffee and the My-Kap Kap.4. Use a coarser grind, as described in another review, if you grind your own coffee. Limit the cup size when using My-Kap Kaps  or other K-Kup re-use devices to 6 oz or less to make the coffee stronger rather than adding more coffee to get an 8 oz or 9 oz cup.
I get 8 oz bottles of spring water by the case, so brewing a cup involves popping in a K-Cup and emptying a bottle of water into the reservoir. Unless you like coffee that tastes like dirty water, I can't imagine getting an acceptable result putting more than 9 oz water through a K-Cup. I never even go to the 9 oz maximum fill because I like my coffee on the stronger side.
It made a full 9 oz cup of coffee (unlike the Keurig.) The coffee tasted great! It was hot enough for me (the Keurig was way to hot for my liking.) In my opinion this coffee maker is not only made better but also looks better than the Keurig model that I had. It's not huge (like the Keurig) and since I don't have a lot of counter space this was a big plus for me.
This Mr. Coffee is definitely a good value, especially if you snag one on sale (I got mine on Amazon for $55). It works well and is easy to use, brews a cup in under 2 minutes. I happen to use a 9-oz. mug, so it's perfect for me -- designed to brew an 8-oz. cup, but the reservoir does accommodate 9 ounces. However, a 10 or 12-oz. water reservoir would be nice.
We have a full-sized Keurig at home but it ws too big to travel with us in our trailer. So we bought this instead. It works well, my only concern is the small size water reservoir - its a little too small for the standard mug so the brew is a little stronger and the fluid a little less.But we're enjoying it - several times a day!
EverynK-cup comes with so much coffee in it the strength of the brew is perfect.I can't see using only 6 or 8 oz of water for these one cups. The coffee would be too strong.Sometimes i'm able to reuse a k-cup for a second brew, especially if the k-cup is a bold coffee.The main reason I use this is for a bit of variety. I would not use it for my home brewing exclusively.
pour in 8 oz. of water6. close the water reservoir7. put the coffee cup in position8. push the brew buttonOpening the water reservoir seems a tad awkward. But it isn't a big deal.I put 8 oz. of water into the coffee cup, pour that into the reservoir, then put the coffee cup into position.After the brew cycle completed, it runs a little air through the K-cup. After that, I just pulled out the K-cup and threw it away.
I saved & saved my money to buy a Keurig, and when I saw this model in the store, I was so happy. My happiness turned to frustration once I was home and realized that it only brews an 8 oz. cup of coffee at a time. I like a rich, strong, full flavor in my cup of coffee, and I haven't had that yet with this coffee maker. I did purchase the reusable filter, so maybe that's my problem with the weak coffee.
While the Mr Coffee maker looks good in my kitchen, I was not very happy with the way it made coffee. I normally make coffee with a 10 oz. cup, so I made a cup. It made the coffee very fast but it was very weak. I rechecked the included instructions and nowhere did I find anything that I did wrong. The only way I could get a half way decent cup was to fill the maker with 5 oz. of water and then brew it.
On the other hand, you use your coffee mug to measure that water and it fills up your mug exactly when brewed. No need to play with the small, med, large... and never get a full cup. Since most of the K-cups could make 1 and half, or even 2 cups of coffee... being able to use a bigger mug and put in that amount of water is actually much more economical. Now in use for 2 months... and going strong.
Answer: You can use less water for stronger coffee. It pierces the top and bottom of the K-cup, so I do believe that it gets thorough extraction. I don't drink a full 8oz cup of coffee, so I usually use about 6oz of water when I brew. The coffee comes out with more flavor in my opinion. I have had no problems with this machine and find it to be a very quality and cheaper purchase compared to the Keurig, especially given that it uses the same technology.
