I love tea for the ritual, taste and theanine, though I appreciate the caffeine in coffee. I don't have a coffee maker, and get chest pains when I drink much coffee as of late, so I started to make cold brews -- 1 cup ground coffee beans in a pitcher with 4 cups cold water, stirred, then put in fridge for 12 hours. Then strained, and the cold coffee can be diluted with water and heated to make reglar stuff, or kept cold and condensed with ice cubes and sugar for lowered acidity, good coffee spritzer. I find that making coffee as such doesn't lead to any chest pains that are probably associated with the acidity level.
