Physical-mechanical process for separating or purifying substances such as liquids or gases using technical filter devices. Various filtration methods are a common process in winemaking. Even in ancient times, the Egyptians, Sumerians and Romans used a technique in which wine was filtered using cloth or similar material. In the Middle Ages, a piece of muslin cloth was used as a filter to remove the added flavouring spices from the wine. This piece of cloth was known as the "Manica Hippocratis" (sleeve of Hippocrates). It was used to make a drink known as hypocras, which is similar to mulled wine and is still produced today according to an old recipe.
For my many years of work as an editor with a wine and culinary focus, I always like to inform myself about special questions at Wine lexicon. Spontaneous reading and following links often leads to exciting discoveries in the wide world of wine.Dr. Christa Hanten
