Here at The Olive Branch we seek to bring a wealth of wholeness to our customers through natural, NON-genetically modified organism certified and gluten free products. Our Artisan quality balsamic vinegars of Modena, Italy are made using ancient procedures. This process begins with Lambrusco and Trebbiano grapes grown in the region called Modena. Grapes are harvested, pressed and treated in copper cauldrons in which the volume is reduced to 40% of its original weight. This liquid is then poured into wooden barrels made from oak, chestnut, juniper and cherry woods. With patience and careful timing, the liquid is then absorbed into the wood of the barrels, aging the balsamic vinegar to perfection!
