Question: how long does it take to brew a cup of coffee?
Document: Another huge bonus is the single cup thing, I've wasted SO much coffee over the years, and now I just brew it as I need it. No more making a 12 cup pot and drinking 2 cups. My only regret is that I waited so long to take the leap to get one.
I do not drink coffee and have not drank anything this machine has made, just to be clear. I bought this for my boyfriend. We had a regular coffee maker for a long time, but he only drank coffee once a week, give or take. Since he wakes up several hours before me, drinks the whole pot, and takes his cup with him in the mornings, I never even noticed he was drinking coffee.
Read through the longer term reviews. I didn't do that and wish I had. I purchased this with a gift card and if I hadn't the review would be much much lower. After about a littler over a year the machine started struggling with making coffee, it would take several minutes to brew a cup with the water just dribbling out. When making cocoa or one of the powdered drinks it was fine.
If you brew the larger cups, you get tea-like coffee-flavored watery beverage with no body or mouth feel and very little flavor. If you take cream in your coffee, forget it. It's like hot watery milk. Doubly so with &#34;commuter cups.&#34; You could never sufficiently fill one of those. You'll end up with half a cup of warm brown water.If you like weak coffee (and a lot of people do) you may well like this thing.
This Keurig has made me a connoisseur of coffee, tea, cider, hot cocoa - all of it. It's so easy to use. I was a late adapter to the single brewer system, but after beginning to drink coffee and realizing I was wasting so much coffee with our old brewer, it was time for something easier to use. Now the whole family uses it. The system is simple to use, doesn't take long to start up and the water reservoir is easy to remove and fill up.
My wife and I wanted a coffee maker that allows us to brew single cups. We looked at a number of products and chose Keurig based on design and simplicity. We have not been disappointed and like the flexibility of just brewing a cup of regular coffee followed by a cup of decaf or just hot water for tea.We like the product and hope to enjoy it for a long time.
I bought this product for my home so that i could take my B130 to the office. One of the big selling points to me was the adjustable thermostat. One thing I never liked about the B130 is that the brew temperature is not sufficiently hot for my tastes, so I was hoping that the K65 would solve that problem- it does not. The default temperature on this machine is already set to maximum, and it produces coffee that is no hotter than the B130 as far as I can tell.
No lie! The ONLY thing I dislike about it is how long it takes to kick on sometimes. Usually I turn mine on when I want a cup (obviously..) and then I have to wait like 5 mins for it to be ready to brew.
I don't know why I took so long in purchasing one of these machines. It has since made our lives so much simpler. It takes it but a couple of seconds to brew me out a fresh cup of whatever i'm drinking. The clean up is so easy, just remove the K-cup and discard. Machine is easy to maintain and easy to operate. It is all that I expected it to be and am very pleased. As for the loudness some reviewers mention, well not mine.
This is my second Keurig and what I love about this one is the water holder. My old one didn't die, I was just ready for something bigger and of course, I really wanted the water holder. I can't believe I went for so long without one! No more refilling the water for each cup- now I can actually brew two mugs back to back. The only gripe I have, which obviously isn't much of one since I still gave it 5 stars, is the splatter.
Answer: With the brew temp set at the default (192 degrees F) a medium size cup takes 1 minute and 7 seconds.  There are three cup sizes so naturally it would take slightly less time for the smaller cup and more for the larger cup.
