Special Products 
			
			Bavaria has several special products to contribute to the foodstuff 
			and beverage industry. First of all there are the 40 or more 
			different kinds of beer, brewed with hops from Bavaria's Hallertau - 
			the largest hop-growing area in the world - and also the Spalt in 
			Franconia. Bavarian beer is brewed according to a purity law passed 
			by Duke Wilhelm IV in 1516. Ever since, German and Bavarian brewers 
			have made certain that their beer contains only water, hops and 
			barley.
			
			
			Wine was grown all over Bavaria during the Middle Ages, but today 
			the industry is mainly limited to the Main region of Franconia. A 
			special characteristic of Franconian wine is the flask-shaped bottle 
			from which it is served, known as a Bocksbeutel. The local vintners 
			gained the right to use this trade mark from the European Union 
			together with a handful of other regional wine areas in Europe.
			
			
			The Bavarians were also the first Germans to plant potatoes for food 
			rather than just decoratively - the event took place in 
			Pilgramsreuth, Franconia, in the year 1647. 
			
			Asparagus is a seasonal product that is harvested from early May to 
			June 24. It is primarily grown in the sandy soil of Upper Bavaria 
			and Swabia.
