and marketing themselves. For other producers, local cooperatives handle the larger quantities of oil. In many cases, there are buyers, brokers, and sellers who sell or buy large quantities to large bottling companies in the producing countries. These producing and bottling companies work for large food chains in Europe and around the world. Up to 80% of EVOO is sold as so-called "private labels" in discount stores and large grocery chains, at least in Europe (**Figure 1**). However, where large volumes are marketed, the trade tries to buy the oils at a minimum price. Inevitably, quality can suffer as a result, especially for EVOO grades marketed as part of so-called borderline oils. These include really bad tasting and sometimes slightly defective oils, which consequently would have to be officially retested to get clarity for the classification.
