Yesterday I sipped a draft of the newest member of the Guinness family, and perhaps the first on tap in North Carolina (according to bartender Ethan at M'Coul's).
Other places should be getting it in the next couple of days, he said.

The new brew is different than the Guinness Draught that you're used to having. And don't expect to see that nifty "waterfall" effect that you're used to seeing in the Draught. That effect comes from nitrogen that comes out of the Draught when it's in the glass.
Nope, the 250 is richer in flavor, and fizzier in its carbonation. There's no nitrogen tap such as those found on a Guinness Draught tap - i.e., no black thingy at the end of the tap faucet - so the 250 relies on the same type of carbonation that other beers have.
In all, it's like a double stout, but not super-sweet as some double stouts end up. The 250 is also a part of a big celebration for the 250th anniversary of signing of the 9,000-year lease that Arthur Guinness signed in 1759. Worth a sip for those who like 'em dark.
