be different due to terroir. The names of these European wine regions are protected so that wines from different regions and different terroir are not confused with wines from that those regions – i.e. A Spanish or Australian "chianti". In the United States there is some confusion over the use of semi-generic names like Champagne and Port but there has been more effort by the American wine industry to recognize the unique association of place names with the wines produced in those places, such as the 2005 Napa Declaration on Place agreement. While appellation systems and the protected designations of origin can be a way of protecting "unique terroir", the commercial importance of terroir has been a much debated topic in the wine industry. In Spain in 2018, networks of vintners joined in a grassroots movement to produce wines with added terroir value with intention to enhance the Spanish rural wine culture. Commercial interests The importance of terroir affects the price of the agricultural product as well as the products made from the product. Branding, variety, and farmer identification affects the price of a product. The Slow Food movement appreciates history of a variety of plant or animal, the story of the farmer who produced it, and ultimately the quality of the product. Chefs and bakers develop their own list of qualities they desire for their creations, and terroir affects these. Wine critics question the value of a Pinot noir wine from a Burgundy Grand Cru vineyard relative to a wine produced from the "lesser terroir" of a Premier Cru vineyard, and whether it merits the higher price. These doubts also arise when the quality of winemaking and other human influences are taken into account, which may be of a higher standard with the "lesser" premier cru. These critics also question the difference between New World and Old World wine and whether modern winemaking techniques – like significant oak influences, over-ripened fruit, cultured yeast, micro-oxygenation, and color pigment additives – obscure or even eliminate the influence of terroir in making different regions unique. Critics often point to the homogenizing effect on mass-produced wines made from popular varietals like Chardonnay, which may have their terroir characteristics hidden by invasive and intensive winemaking. A heavily oaked, over-ripe Chardonnay from California can taste very similar to the same style of wine from elsewhere. The marketability of wines from different regions and producers is
