Sometimes, you may not feel like making a trip to a cafe/restaurant to get a quick cup of coffee, or making your own brew; you might even wake up feeling too tired to do that anyway. For convenience and ease, I bought a large pack of SToK “Espresso” shots, which are little single use plastic cups of concentrated coffee. Just peel and shoot, and you’ve already got a cup of coffee’s worth of caffeine in your system. SToK shots are not technically Espresso shots, since Espresso is defined as going through a special process, but are cold brewed coffee that is concentrated. Another use of these is simply to add more kick to coffee, to pour over ice cream/desserts, or for use in some alcoholic cocktails (White Russian, eggnog, hard Irish cream).
