Nitro Beers
BE Nitro beer

Who has never stared at the glass while a bartender is pouring a Guinness?
Isn’t that beautiful?

That effect is caused by nitrogen.

The appeal of nitro beers is spreading well beyond the fans of the Irish beers. More and more craft breweries are using this method to create a creamier fell in their beers.

A typical nitro beer replaces 70% of the carbon dioxide by nitrogen.

Nitrogen doesnt dissolve in liquid and that is exactly what contributes to the creamy feel.
In order to get this effect you also need a special piece inside your tap machine that forces the beer through very small holes before reaching the glass.

This process lends a creamy texture, a beautiful white head and the famous reverse waterfall effect, where the bubbles seem to drop towards the bottom of the glass

Normally we find more porters and stouts on nitro because this method helps maltier beers to become smoother and creamier. But it doesn’t play that well with hoppier beers - this process strips off the hops’ flavours and aromas that are so desired in hoppy styles.

But nowadays no experimentation is out of question, so nitro beers are becoming more popular even outside the typical styles.

Left Hand Brewing Company is one of the new breweries that is investing in this beers. In 2011 they released their already famous Milk Stout in the nitro version.

Some breweries, such as Bridgeport Brewing are offering the same beer on both types of taps (with and without nitrogen) side by side, so you can notice how nitro can change a beer: nitrogen makes the beer’s texture creamier and the flavours more evenly distributed. Beers with only carbon dioxide are more aggressive on the tongue and with stronger aromas.

Boston Beer Co is another company that is playing with the nitro beers. They released (draught only) a new stout nitro beer into the Boston and New York markets which are two of the biggest consumption areas for this style in the country.

Oskar Blues also has released their Old Chub Scotch Ale in cans outfitted with plastic widgets that release nitrogen into the beer when the tap is pulled.

This idea is becoming more popular as brewpubs are adding nitro tap lines in their establishments.

Nowadays nitro lines for bars are much more affordable. And now if a bar wants to stand apart from the crowd, it has to buy some of those lines.

The popularity is easy to understand! Who doesn’t love that cascade effect on a nitro beer glass ?
