In a large nonreactive jar, combine lemon zest, juice of 3 lemons, sugar, pineapple, cloves, coriander, cinnamon, brandy, rum, arrack, green tea, and 2 cups boiling water. Stir until sugar dissolves. Cover and refrigerate for at least 6 hours or up to 2 weeks. (The longer the mixture steeps, the smoother and more nuanced the flavor becomes.)
In a medium pan, bring milk to a boil. Remove from heat, and add lemon juice; stir until curds and whey have separated. Carefully add to pineapple mixture.
Strain mixture through a large-mesh sieve, discarding solids. Strain mixture through a fine-mesh sieve, discarding solids. Strain mixture through a fine-mesh sieve lined with a coffee filter or double layer of cheesecloth. Replace lining as needed. Cover and refrigerate until remaining sediment settles. Ladle or slowly pour mixture into a new clean jar, leaving sediment behind. Discard sediment. Cover and refrigerate until cold. Serve in a Nick and Nora glass.
