Also known as grape oil, grape berry oil or wine seed oil, this product is obtained from the grape seeds contained in the press residues (pomace) by cold or warm pressing or extraction and is used as an edible oil. Cold-pressed oil has a light green iridescent colour and is slightly nutty in flavour, with the grape still recognisable in taste. Besides fatty acids, it also contains the antioxidants vitamin E, resveratrol, proanthocyanidins and lecithin. It is well suited for seasoning salads and sauces, with cheese or for pickling meat. The press residue from cold pressing is processed into grape seed flour. Hot-pressed oil is an edible oil that is neutral in taste and colour. It contains smaller amounts of natural fatty substances. Grape seed oil is also used as a basis for cosmetic preparations and in vinotherapies; its effect was already known in the Middle Ages.
As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.
