Several substyles exist, including maibock (helles bock, heller bock), a paler, more hopped version generally made for consumption at spring festivals; doppelbock (double bock), a stronger and maltier version; and eisbock, a much stronger version made by partially freezing the beer and removing the ice that forms.
Scientists describe seven basic tastes: bitter, salty, sour, astringent, sweet, pungent (eg chili), and umami. There are however five basic tastes that the tongue is sensitive to: salt, sweet, bitter, sour, and umami, the taste of MSG.
Sweet taste is also found in milk and milk products (like butter, ghee, and cream), most grains (especially wheat, rice, and barley), many legumes (like beans and lentils), sweet fruits (such as bananas and mangos), and certain cooked vegetables (such as carrots, sweet potatoes, and beets).
