Pour out enough vodka from the bottle in order to make room for the peppers and reserve for another use. Carefully add the peppers and garlic to the vodka, pouring out more liquid if need be. Cap and let stand at room temperature until the vodka acquires the desired heat, about 1 week.
Serve, or remove the peppers and keep in the freezer.
