Nitro 

 by Crush Wine Bar

There is something poetic, almost romantic, about a freshly-poured pint of stout from a nitro tap. The cascading effect is mesmerizing; the waterfall of tiny bubbles slowly yielding to a dark brew with a fluffy, white head thick enough to float a bottle cap.

While nitro is normally associated with a certain brewery of Irish heritage hailing from Dublin, more and more craft breweries are embracing the nitrogenated method and adding such beers to their lineups. The number of bars adding independent (non branded) nitro taps is growing as more establishments embrace craft beer and buck the traditions of larger breweries.

When people talk of nitro, it’s a reference to the type of gas used in the carbonation process. It means the difference between the creamier nitrogen beers (N2) and their lively, prickly CO2 counterparts. A typical nitrogenated beer contains about 70 percent nitrogen and 30 percent carbon dioxide.

Nitrogen is largely insoluble in liquid, which is what contributes to the thick mouth feel. This effect is helped by a special piece of tap equipment known as a restrictor plate that forces the beer through tiny holes before it lands in the glass. That process causes the “rising” effect that is topped with the head. And it’s really only the bubbles on the sides of the glass that fall. Inside they are actually rising, as typically seen with a poured carbonated beverage.

At Crush we are not just a wine bar ,we have the same passion for beer. One of my all time favorites is from Left Hand Brewing Company in Longmont, Colo. "Milk Stout" we have a nitro tap dedicated to this delicious nectar, come try one!!!
