American-style black ales are very dark to black and perceived to have medium high to high hop bitterness, flavor and aroma with medium-high alcohol content, balanced with a medium body. fruity, floral and herbal character from hops of all origins may contribute character. the style is further characterized by a balanced and moderate degree of caramel malt and dark roasted malt flavor and aroma. high astringency and high degree of burnt roast malt character should be absent.
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.
