Light amber to mid-range brown in color, strong ales are medium to full bodied with a malty sweetness and may have low levels of roast malt character. hop aroma should be minimal and flavor can vary from none to medium in character intensity. fruity-ester flavors and aromas can contribute to the character of this ale. bitterness should be minimal but evident and balanced with malt and/or caramel-like sweetness. alcohol types can be varied and complex. a rich, often sweet and complex estery character may be evident. very low levels of diacetyl are acceptable. chill haze is acceptable at low temperatures. (this style may often be split into two categories, strong and very strong.)
The number one reason is craft beer tastes better than the "beer water" that is mass produced and mass marketed by the big beer companies. Craft beer tastes better because craft brewers spend their time focusing the quality of their beer rather than focusing on their marketing campaigns and stock prices.
Oh yeah! Craft beers can pack a punch. Most craft beers range from 5-10% ABV, but some can reach 20%, 30%, and even 40% ABV.
