Choose a good quality Italian red wine, such as Barolo for this rich, vegetarian risotto. You can increase the amount of red wine for a stronger taste, say an extra 60mls with the last ladle of stock so the taste is more pronounced.
Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
