The best cup of tea I've ever had was made by my friend's Irish husband. I don't know what he did, but something about the ratio to the milk, sugar, and tea was just perfect!
I like tea in general, but I tend to drink more black tea than green tea, and herbal tea is usually just for when I want to relax, or when I want something warm with no caffeine. Chai tea and Earl Grey are my favorite black teas.
