We’ve come a long way from the cans of Folgers that filled our grandparents’ cupboards, with our oat milk lattes, cold brews and Frappuccinos. Some of us are still very utilitarian about the drink while others perform elaborate rituals. The fourth most popular beverage in the country, coffee is steeped into our culture. Just the right amount can improve our mood; too much may make us feel anxious and jittery.
