![]() ![]() Some bars are adding more nitro lines, but it’s not a big focus for many. ![]() Guinness has had a monopoly on “that one weird tap” for decades, which will likely cause problems as more breweries jump into the fray. Unlike Frank the Tank’s Red Dragon, the nozzle on nitro taps have a restrictor plate added to slow down the pour and aerate the beer. Not only does a special gas blend (also 70% N 2 and 30% CO 2 ) force the beer to the tap, the nozzle itself is unique. Speaking of taps, they play a big roll in nitro beers. Try both if you happen to be in a bar with options on tap. The same beer side by side, one nitro and one standard, will be worlds apart. ![]() Whereas carbonation helps make a beer crisp, lively, and in some cases bitter, nitrogen smooths out the flavors and makes the overall mouthfeel much creamier. You can tell the difference the second the heavenly nectar hits your mouth. Nitrogen doesn’t just affect the visuals of a beer either. As the beer falls back down along the side of the glass it pulls some of these tiny bubbles with it, creating the mesmerizing visual. As the bubbles rise in the center of the glass, beer is pushed up and to the side. Many have wondered how it’s possible for gas filled bubbles to sink instead of rise, but the answer is pretty simple. If you’ve ever watched the bubbles in a Guinness, you’ll know what we mean by cascading. The bubble size also contributes to the telltale cascading effect. It’s a frat party’s worst nightmare but a beer lover’s wet dream. Their small size makes N 2 bubbles more stable, resulting in a thick, long-lasting head. N 2 bubbles are significantly smaller than CO 2 bubbles. And while there’s plenty of chemistry at play that’s well beyond me, there are a few easy ways to recognize differences between nitrogenated and carbonated beer. Nitro beers are created by adding a mixture of gasses that’s 70% N 2 and 30% CO 2. The process took 4 years to perfect, but in 1959, pints of Guinness began using nitrogen to achieve the creamy taste and signature cascading effect for which it’s known. In the 1950s, Michael Ash had the brilliant idea that beer could be made using nitrogen, and he was hired by Guinness to make it happen. There’s a good reason for their status, too. Guinness is the most well known nitro beer on the market, even if you never realized that’s what made it different. That doesn’t mean there aren’t options beyond additional carbonation though, like say… nitrogenation. The result is beer that’s fresh for much longer than the cask ales of ye olden days. It’s a method in which additional CO 2 is dissolved into the beer before it’s bottled, kegged, or poured directly into my cupped hands. The vast majority of the beer you’ve consumed in your lifetime is force-carbonated. ![]() And while it might not be a noble gas, nitrogen definitely results in noble beers. thanks to big brewers like Samuel Adams and Founders releasing their respective Nitro Beer Project and Nitro Draft Series. © 2022 iKegger Australia.Nitro beers are far from new, but the category is getting a lot of hype in the U.S. South Georgia & South Sandwich Islands (GBP £) You can also use the drop-down menu to choose options for connecting directly to a keg with a steel or plastic connection. The tap alone is for connecting to your existing system, it matches commonly available shanks and fonts. You can use this as a normal beer tap by removing this restrictor from the spout. If the tap isn't flowing and everything else seems to be fine (keg is pressurised etc) then likely some sediment has blocked these tiny holes, remove the spout of the tap and clean them out to continue pouring. This is a circular disc with 5 small holes in it.īy forcing the liquid through these holes the dissolved Nitrogen is separated and as it releases into the glass it forms the cascading style head made famous by Guinness. The liquid is forced through a nozzle on the tap with a restrictor plate in it. They are more difficult to knock accidentally than other beer taps as they are spring-loaded to stay closed. They have an action that allows pulling the handle forward for a continuous pour or pushing back for a burst of dense head. These taps are specifically designed for Stout and Nitro Coffee systems. ![]()
