Ginger vodka is a vodka infused with ginger flavor and usually a bit of sugar. Some common brands of ginger vodka are Skyy, Yazi, and Modern Spirits (which is infused with candied ginger). These products are usually 70 proof.
Ginger vodka has a warming, spicy quality, and is a good candidate for homemade infusion. Ginger vodka should not be confused with ginger eau de vie, which is made from fermented ginger.
