The surrounding region is well known for its vineyards, particularly so for the production of fortified wines such as port, muscat and tokay, the best of which are regarded by many as Australia's and some of the world's finest. However, it also produces good-quality red and white wines, notably shiraz, as well as the relatively uncommon production of sparkling red wine—red wine with carbon-dioxide induced bubbles made in a similar process to champagne.
