Step 1

Heat 2 1/4 cups of water to 208°F. If you have an electric kettle with a temperature setting, great. If not, bring the water to a boil in a saucepan, kill the heat and count to Pour the water over the teabags into a quart vessel and steep 3 minutes before removing the bags. (Do not wring out or squeeze the bags.)

Step 2

Add the sugar to the hot tea and stir to dissolve. Then add the port, rum, Allspice Dram, and lemon juice. Cool to room temperature, about 20 minutes.

Step 3

Pour the milk into a glass pitcher and then follow with the tea mixture. (Yes, it will curdle.) Park on counter for 1 hour. Do not shake, stir or molest in any way. Just let the magic happen. Oh, and make sure the tea goes into the milk, not the other way around.

Step 4

Line a large, fine-mesh sieve with a commercial-sized coffee filter (we like those made for 1.5-gallon machines) and strain the mixture into a wide, 4-quart container. Once completely filtered, typically about 1 hour, transfer to a quart jar or pitcher and chill to serve. (See note.)

Step 5

Store tightly sealed in the refrigerator for up to 2 months.
