Strain through a fine-mesh sieve into a medium bowl, then return tea to saucepan. Add ginger, orange zest, sugar, and half a cup of mint; return to a simmer over medium heat, stirring occasionally to dissolve the sugar. Let cool.// Strain tea syrup through a fine-mesh sieve into a pitcher, pressing on solids, then discard solids. Stir in gin and lemon juice and chill until cold, for about an hour.// Pour into rocks glasses filled with ice garnished with lemon wheels and mint sprigs, and serve.
