I used a Saumur, but any inexpensive fruity red wine will work. Aperitifs like this are meant to be made with inexpensive red wine, so no need to feel like a cheapskate. You can easily increase the recipe if you’d like to take advantage of the availability of young peach leaves, which give the wine a surprisingly tasty almond flavor. Do check with your local cooperative extension or nursery first if you have any questions about whether your peach leaves are edible.
