Well, this is certainly big news in the craft beer community, news Russian River’s Vinnie and Natalie Cilurzo have been playing close to the vest. They’re teaming up with Dogfish Head and two Italian craft breweries to open a rooftop brewpub in New York City. Dogfish Head issued a press release this morning with the details. From the press release:

Four well-know brewers are joining forces with Mario Batali, Joe Bastianich, and Italian food emporium Eataly to open a brewery-pub on a New York City rooftop with breathtaking views of the Flatiron and Empire State Buildings.

The four breweries collaborating on this project include two Italian craft brewers — Teo Musso, Brewmaster of Birrificio Le Baladin and Leonardo Di Vincenzo of Birra del Borgo, and two Italian-American craft brewers — Sam Calagione of Dogfish Head Craft Brewery and Vinnie Cilurzo of the Russian River Brewing Company.

The first floor of the building at 200 5th Avenue will house Eataly, an epic Italian specialty foods market and multiple restaurants which pair gourmet foods with artisanal beers and wines. Additionally, there will be an 8,000 square foot rooftop brewery and restaurant operated by B&B Hospitalitys Mario Batali and Joe Bastianich.

The rooftop bar and restaurant will house a copper-clad brewing system. The idea is to create an artisanal, old world Italian craft brewery that just happens to be located on a rooftop in Manhattan, says Dogfish Heads Sam Calagione. The four brewers are working together on recipes for Eatalys house beers. Those beers will feature Italian and American ingredients. The beers will be unpasteurized, unfiltered, naturally carbonated, and hand-pulled through traditional beer engines for the most authentic and pure presentation. The four individual brewers will also occasionally brew beers under their own names on site. The rooftop restaurant project will pair artisanal rustic, homemade beers with the artisanal, rustic cooking of Chef Mario Batali. Additional Italian and American regional craft beers will be served both at the rooftop bar and within the downstairs restaurants.

The four consulting brewers met in Boston this week to brew the first test batch of Eataly beer, an English Mild fermented with Italian chestnut powder (photos above). Plans call for Eataly New York to open late summer 2010.

More from the press release:

“Eataly is the representation of the earth, its products and an example of real Italian taste. The brewery will surely be a fusion of Italian and Italian/American styles and I am very happy to make this journey with this fantastic group!” Teo Musso, Brewmaster , Birrificio Le Baladin

“In 2006 I went to the Slow Food Salone del Gusto in Italy. Upon meeting many Italian craft brewers, I was not only impressed by the quality of their beer, but, their passion for brewing as well. It was at that time I learned how great Italian craft beer was! To now collaborate with two of the most dynamic Italian craft brewers along with my friend Sam Calagione at Eataly New York will not only be a lot of fun, but, very educational as well.” Vinnie Cilurzo, Brewer/Owner, Russian River Brewing Company

“Eataly Brewery will be a great fusion of the well-known Italian gastronomic culture and our rising beer culture with the taste and the creativity of the American craft beer movement. This may well be the craziest and amazing brewery in the world” Leonardo Di Vincenzo, Brewmaster, Birra del Borgo

“While the Italian craft brewing renaissance started later than ours here in the states , they have quickly made up for lost time with world class artisanal beers. Both Dogfish Head and Russian River have pushed the boundries of beer, particularly those that pair well with food, for many years. We are looking forward to working with our Italian Brewing Brethren, Mario Batali, Joe Bastianich, and the folks at Eataly to further strengthen the bond between world class beer and world class food in the most beautiful setting for a brewery I have ever seen.” Sam Calagione, President/Founder, Dogfish Head Craft Brewery.
