    Question Nitro Coffee Speed Stout?

    Waht do you think
    smooth as steam or frothy as the Duke of Newcastle's drawers

    Nate Armbrust, a food scientist at Stumptown Coffee Roasters in Portland, Oregon took on a lofty side project in early 2013: He wanted to figure out how to infuse cold brew coffee with tiny bubbles that would make it rich and creamy without sacrificing its flavor.

    So he decided to try pumping nitrogen gas into the brew.

    Turns out this was a very good idea.

    After a few months of playing around with the right balance of bubble infusion, according to Chemical and Engineering News, his nitrogen-infused cold coffee became creamier and richer than regular old cold brew an instant hit after putting it on tap at his Portland cafe.

    Nitro taps aren't new. In fact, they've become notorious in the craft beer scene after getting their start in Irish breweries. They've imbued ales, stouts, and lagers with a lush, rich-tasting froth ever since.

    But how does it work?

    When someone says that a beer is "on nitro," they're referring to the type of gas bubbled into the drink. Breweries typically use carbon dioxide to give a beer its quintessential bitter fizz. But sometimes a drink calls for a sweeter, silkier experience. So brewers commonly infuse darker, smoother stouts and ales like Guinness and Old Speckled Hen with nitrogen rather than carbon dioxide.

    The creamier taste either in beer or in coffee is due, in part, to the smaller nitrogen bubbles.

    Nitrogen gas doesn't easily dissolve in water, giving the brew a thicker, more velvety "mouthfeel." To get nitrogen into the liquid, the tap needs a "restrictor plate" to squeeze the drink through tiny holes, giving the beverage a particularly smooth and frothy head.

    The tiny bubbles make the drink feel thicker when you gulp it down.

    Widget (beer) - Wikipedia, the free encyclopedia
    https://en.wikipedia.org/wiki/Widget_(beer)
    In 1969 two Guinness brewers at Guinness's St James's Gate brewery in Dublin, Tony Carey and Sammy Hildebrand, developed a system for producing draught type Guinness from cans or bottles through the discharge of gas from an internal compartment.

    Yea, that was always going to happen..can't remember the details of the dispute and Camerons is long gone in it's old form.

    Anyway...Draught Guinness from the can is good 'if' you can't get the real deal.

    Sure sorry I thought I's pasted it.

    Here's why coffee shops are bubbling nitrogen into cold brew - Tech Insider

    P.S.

    A handy tip for specialized text if you just cut and paste a fair chunk and google it usially find source even a TD post if searchable.

    Obviously simple lines like Ausralia win ases brings millions or UK Brexit but the text above is a perfect example
