(MPWWine) - The approach to making wine varies widely among producers of wine. There is wine made by passionate small farmers and winemakers who value the natural properties of the fruit and the wine. Then, there are the bulk wine producers that turn out millions of liters of wine every year. It is not surprising that the latter style of winemaking would embrace the use of additives that allow them to make wine more cheaply or efficiently. It turns out that most consumers have no idea what is occasionally, and sometimes frequently, done to their wine during the winemaking process as well as what may be added to the bottle. We think you may be surprised to see a list of additives that are currently allowed in the US. These are ingredients you may not see on a label but could be added to your wine without your knowledge.
