Transfer the strained chai concentrate back into a medium saucepan. Bring to a near-boil on the stove. Meanwhile, prep two mugs with two bags of black tea each.
Pour the hot concentrate over the tea bags in each mug, dividing evenly between each. Let steep for 5-6 minutes. Press excess water out of tea bags before removing.
While tea is steeping, combine milk and honey and froth using a milk frother or other method of choice. Divide frothed milk evenly between the two mugs of tea and serve immediately.
