About Us / Peterson and Sons Natural Wines History: Peterson and Sons is one of the very few wineries in the world that makes wine without chemicals or preservatives. We use only the best, hand picked or sorted Michigan fruit, water, sugar and yeast, plus a lot of time and personal care. Our wines will keep and age once opened if kept below 70° F. Because no chemicals are used to kill anything, CO2 gas can result several months after bottling, so please store the bottles upright and at a constant temperature of 55° to 70° and out of sunlight. We use synthetic corks so you don't have to store bottles on their sides.
