I like to drink two cups of coffee, so I've started making my second a half caff to avoid the jitters. There aren't a ton of choices on the market in K-cups. I've tried a few and keep landing back on the Green Mountain variety. The Maud's/World's Best tend to stop up our old Keurig! In fact, we bought a new one just because we thought it was broken. Not only is Green Mountain flavorful, it's apparently easier on the brewer.
After opening the package, one of the containers was partially smashed resulting in several of the cups being smashed in, one was unusable because the cup had a slit in it. Other than that, I really much like the half caffeinated coffee.
This coffee is perfect for someone like me who wants a little wake-up, but not a full blown shot of caffeine. I mix it with cocoa and milk for a perfect cafe mocha latte to sip while my eyes open. Any more caffeine and I would feel the effects all day.
