Fill a large (1 liter+) jar with sliced peaches. Cover fully with vodka, making sure the peaches are fully submerged.
Let sit in a cool, dark place for at least 3 days, or up to a week.
Strain through a fine mesh sieve. To extract maximum flavor, squeeze the peaches through cheesecloth into the vodka to squeeze out any excess moisture.
To make the cocktail, fill a glass with ice.
Add in the peach infused vodka, freshly squeezed lemon juice and ginger beer to top it off. Stir gently. Optional: top with peach slices for garnish.
