NewCastle is best on tap. I thoroughly enjoy 22 oz draft beers of NC.
Sam Adams is quietly becoming the next BMC. Obvoiusly no where near that scale, but whenever an event wants a "nice" beer, Sams is the choice they stock up on. Its the - everyone recognizes and likes it, they have a Lager, a Light, and Seasonal choice - beer.
I've noticed their prices jump the past two years. I usually get 6ers of the Blackberry, Cherry Wheat, and other ones, but its gotten too expensive so I buy other nice craft beers at equal or lesser value. (Except the god awful Summer, and I am apparnetly the only one sad the White was replaced by Noble Pils, and the White is only an occasional release in 6 packs now)
