I would say roughly 3.5 cups. Although, the buttons are marked in ounces so you learn pretty quick what an 8oz mug and a 10oz mug look like. And you can play with the combination. For instance, my wife has a few 20oz mugs, so I might run the same K-Cup through three times on the 6oz button, or do two runs on the 8oz. Just depends. Note, you're standard mug is 8oz, the one's your grandparents used are usually 6oz and most modern mugs run around 10-12oz.How many cups does the keurig reservoir hold?
All valid points. As I don’t own one, I can’t vouch for the cleaning regimen or water quality those are partook from. One common point is that they all had an assortment of flavored creamers lol. The Keurig at my kids swim school has water ran from the wall so I’d assume city. Whether it is filtered outside of that I don’t know.
I’m not a fan of instant either really- they to me have a very predictable flavor as well.
But there is enough in the reservoir to make three 10oz runs before refilling. Our model is the Essentials Express, so the reservoir is smaller than the standard Keurig. So, there's that.
