Have been using Bunn coffeemaker for several years. Need to add water to the preheated tank. How can we add two cups of water to have a full ten cups of hot water to fill coffee pot, instead of eight cups coming through?

Can only four cups be made, or do we always need to make the full pot?

P.S. To settle an argument...
How much electricity does it take to keep the pot hot? I say more than keeping a night light on all day, my husband disagrees.

Thank you.


Dear Jim & Kay,
The reduced volume you see is attributed to retention of water in the spent coffee grounds.
On average the grounds hold back approximately two ounces of water per one ounce of ground coffee.
You can brew a half-decanter of coffee. I would suggest using slightly more than half the grounds due to low bed depth of grounds creating a faster drip through. Experiment!

Happy Brewing,
Dr. Brew
