Last night I mixed about 1/4 cup Matcha Latte mix with a couple of tablespoons of warm water, stirred it a bit, then I added about 3 cups (or roughly 750 ml) of dry gin and shook it up a bit. I will infuse the mixture for about 7 days and then keep it in the freezer. I want to minimize the risk of oxidation and also keep the flavor green-tea like.
I’ve made this type of drink once before using about a tablespoon of matcha and maybe 3/4 cup sugar (it was a sweeter drink last time). I usually drank it after dinner served extremely cold, just pulled from the freezer. In that case it was more of a strong liqueur; it had a heady green tea flavor but was sweet enough that it needed to be blended with some shochu or vodka to cut the sugar.
I will infuse it for about 7 days. After that I will store it in the freezer to minimize additional oxidation, so that I can keep the color as green as possible. I think it’s discolored a bit since I first made it last night since it was more of a emerald color originally, but a little bit of color change is probably unavoidable.
I’m hoping it will make for a nice martini, just shaken and poured into a glass washed with vermouth. The last version of this I made worked for a martini but was more of a digestiv-style drink.
