"According to bar expert and author John deBary, to wake yourself up and give a nod to the Brits, tea-infused spirits are the way to go. You can infuse "english breakfast or earl grey tea into London dry gin like Beefeater or Sipsmith,” and go with whatever gin cocktail you already know and love. And you don’t even have to have planned it the night before. “I usually do 14 grams (or 7 standard tea bags) infused into one 750 mL bottle of gin for 10 minutes,” he says. If you have a few bags of Lipton and half a bottle of gin hanging around somewhere in your apartment, you're halfway there."
