I have an older Keurig coffee maker. It doesn’t have the cup size selector. But, I use a 12-0z size mug so I put in 12 ounces and only 8 come out! Where is that water going? Does it just sit in there and then I get old water the next time? Is there any way to force it to use the amount of water I put in?:mad:
Some of the missing water is in the K-cup. It’s now full of wet grounds that used to be dry. That wetness had to come from somewhere. That missing water will be thrown away when you throw away the used K-cup.
Some of the missing water is in the machine’s plumbing. And will be the first water in the next cup you brew. Big deal. Water doesn’t spoil.
Some of the missing water evaporated as steam. That water is gone for good.
If your complaint is that your cup isn’t full of coffee when the machine is done, simply add enough more water mid-cycle to make up the difference. Yes you can overdo that and make a mess. Practice makes perfect. And yes, it requires a second cup to pour from while your main cup is filling with coffee. Oh well.
A conventional drip coffeemaker has the same problem. If you fill the carafe to the top and run it, you’ll find when it’s done there’s about 1/2 a cup less coffee in the carafe than there was water at the beginning.
is this a one-time occurrence? I suggest that you tally up five cups of coffee, and see what happens. If you put 60 ounces of water in, and got only 40 ounces of coffee, then you have either a wet mess on the counter or a very magical keurig.
As I suspected, in the answer above, it’s mostly still in the plumbing apparatus (4oz that just stays there) and comes out the next time I use it. So it’s sitting there for sometimes a few days. Ugh. Since I apparently have the 8oz Keurig (the old style) there must be no way to force it to brew 12 oz. the water reservoir won’t hold 60 oz so I can’t do as you suggest.
Rats.
I’m not quite understanding your challenge. It seems you have a 12 floz cup and want 12 floz of coffee to come out. But the machine has an 8 oz reservoir.
I think you can fill the reservoir to 8 oz, then start the brew process. After much of the water is consumed, just pour another roughly 7 oz in there. So 13 total. About 12 will end up in the cup, and 1 will end up as steam or in the K-Cup. Viola.
If the machine auto-shuts off after 8 oz., so that refilling-the-reservoir trick doesn’t work, then do this:
Put roughly 7 oz. of water in the reservoir. Brew that, getting about 6 oz of coffee. Now add another 7 oz. of water & brew again using the same K-cup. You might have to cycle the cup holder open and closed to fool the machine into thinking you put a fresh K-cup in there before it’ll brew the second batch of water.
I used this last trick a lot on our fancy office machine. It had a big reservoir but only buttons to brew 4, 6, and 8 oz. cups. To get a 12 I brewed a 4 and an 8 out of the same K-cup. Had to cycle the cup handle to fool the machine into thinking I was using 2 K-cups for the 2 brew cycles.
There is no reason to let a mere machine frustrate your goals.
If you don’t like the idea of “old” water being used to brew your coffee then run a hot water cycle (just run the machine with no k-cup in it) before running a coffee cycle.
