Acetaia Leonardi's Francobolli Series (francobolli means "postage stamps") is a selection of three I.G.P. Balsamic Vinegars and a Condimento Balsamico Bianco. With attractive labels that look like vintage postage stamps, this range of vinegars satisfies every balsamic need in the kitchen. Adhering to I.G.P. regulations, Acetaia Leonardi identifies the age and viscosity of their vinegars with a proprietary symbol—coins—with each coin representing approximately 2 years of aging.

Leonardi's Sigillo Argento is a masterful blend of cooked grape must and high quality wine vinegar. Thick as maple syrup, with notes of cooked grapes like a good Amarone, and a long subtle acidic finish.

Drizzle over a sizzling hot grilled steak or pork chop, as well as on grilled eggplant, peppers, mushrooms, and zucchini. Wonderful swirled into butternut squash soup or creamy Parmigiano risotto. Highlight the freshness of freshly sliced plums, nectarines, and peaches. Use instead of caramel or chocolate sauce over baked pears and apples.
