Did you ever walk into a specialty coffee shop and look at all those menu options, and have no idea what you were gonna get? Well, we’re gonna clear up some of that stuff for you. A Red Eye is a really simple drink. It’s brewed drip coffee. You can either take it from a pour over, or a batch brew system, top it off with a shot of espresso. Let’s be perfectly honest. If you’re drinking a Red Eye, there’s only one reason to do that, and that’s more caffeine.
