In a small pot, bring water to a boil, and pour into mug. Steep tea bag for 5 minutes to make concentrated tea.

While tea is steeping, warm milk on medium heat in a small pot. When bubbles start to form on the sides, whisk vigorously until foam layer forms on top.

Remove tea bag from water and stir in sugar to the tea. Then, pour milk into the mug using a spatula to keep the foam out of the mug with the tea. Mix, then pour foam on top.

If using, sprinkle cinnamon or chai spice on top of the latte. Enjoy!
