One thing I like about using my Keurig is that you can get water heated to the temp you want.
So sometimes I just get a 190 degree cup of water, mix in some instant(Nescafe Classico in my case) and presto- a cheap cup of coffee that is of consistent quality. This is because with the temps always the same, and the amount of water always the same, it’s easy to get your mixture perfect for whatever coffee you’re using. Boiling water on the stove or heating it in the microwave doesn’t work as well since the water is always slightly different in some way.
The same goes with making hot chocolate.
Occasionally I’ll buy some beans at a local coffee shop and have them grind them for me. Then I’ll use my French press combined with my Keurig heated water to make an even better cup of coffee. The reason I don’t do that exclusively is it’s too much bother. At some point I have to clean the glass and plunger thingy, dump the grounds out in the garden…anything that takes me away from drinking my coffee is unwelcome. That’s what’s so great about the Keurig plus Kcup system, you press a button and coffee goes straight into your cup. You can then walk away with your cup, tossing the empty Kcup in the trash is all the ‘work’ you have to do.
