Guinness nitrosurge teardown - with schematic

A new twist on the original ultrasonic plate that was used to "surge" the classic Guinness drink to liberate the nitrogen bubbles used to give it it's velvety texture.
The previous version used an ultrasonic disk with a layer of water that you placed the can on and "surged" it before pouring. Guinness uses nitrogen instead of carbon dioxide for its fizz, since the nitrogen bubbles are a lot smaller and give it a distinct creamy texture when you drink it.
With this version the surger is a device that clips on the top of a can and causes nucleation of the nitrogen in a controlled number and length of surges as the drink is poured.
The result looks just like a pint of Guinness poured in a pub. If you look for reviews from Guinness experts you will see the difficulty they have differentiating between a pub poured and surger poured drink.
Things worthy of note. The can has to be held at a suitable angle as shown at the start of this video, to ensure good connection with the cavitation zone and avoid air-bloop resulting in bigger bubbles. It's worth looking at the video showing the inventor of the unit showing it's correct use:-
• How to get the PERFECT...
There is also a pub version that mounts on the bar and semi automates the process, allowing the Guinness to be stored in cans for ultimate freshness.
It's a nice solid design. The ultrasonic atomiser is more robust than I expected, and the circuitry is logical and quite rugged.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.co...
This also keeps the channel independent of KZbin's algorithm quirks, allowing it to be a bit more dangerous and naughty.

The cap at 13:24 is something I always use for getting rid of bouncing switches. Yes, you could do that in software, but a 10nF cap works wonders as a low-pass filter together with the internal pull-up in the uC. 10nF will give you a +/- 2ms delay and a clean on/off signal. Good enough for detecting 25 pushes per second.

@@DUKE_of_RAMBLE Missing the nitrogen/carbon dioxide mix Guinness uses. Half the reason Guinness tastes better in Ireland is because it just does not stay fresh. The ABV isn't really high enough and you can't really pressurize cans high enough to fit the same quantity of nitrogen gas as you could carbon dioxide. Combine the two and you have a beer that even canned only tastes great the same month it's made. Of course, if you're shipping it direct to a bar then it's not sitting on a shelf for two weeks, and on tap you can just add straight nitrogen to it as it's dispensed.

Welch's "Sparkling Grape Juice" I'm *_almost certain_* USED TO BE "carbonated" (heretofore referred to as) with nitrogen, based on what you've described and the absolute density of that foam. I'm now 40, but have been drinking that stuff *every* year (usually at least 3 occasions) for as far back as I can remember, and it *_WAS_* that carbonation which, in all honesty, that made it the best. As of, probably 5 years ago, maybe up to 8, that carbonation changed _drastically..._ much to my dismay. That, as you put it, velvety foam... no longer present. Unfortunately, it's taste has also changed, becoming more bitter. My guess is that's because they switched to now being carbonated with... carbon, now. I figure that part of that flavor change is probably due to a bit less sugar added since the US has changed their Daily Nutrition Values during that same timeframe _(a 12oz can of soda would've been, say "76%" daily value of sugar, but now they're almost all >90% lol)._ The other part I figure it's due to Carbonic Acid. It's still good stuff, but boy, it really is not anything like what it once was. 😔 [/weird ramble]

[@cheyannei5983]

Carbon dioxide is soluble in water. It's why increasing atmospheric CO2 acidifies the oceans. Nitrogen is largely not. Also in the last 10 years, the FDA has clamped down harder on what food additives are safe to use. I don't think they'd be affected, but it's possible some seal or the thick glass required to handle the pressures just got too expensive for a publicly traded company...

Sadly almost every product of our youths has changed due to corporate greed and the corporate corruption of regulatory standards. High fructose corn crap is not natural and needs to be banned to reduce disease.

[@xAlexZifko]

I have no basis for this theory, but perhaps they changed something else in the drink that downline effected the "potency" of the carbonation as well. I'm under the impression welch's is pure fruit juice so it's not a sugar/hfcs situation but maybe their perservatives or something effect the carbonation in some manner. When brewing alcohol you'll find that some bizarre sugar sources will easily ferment, but add just a bit of some element and they'll die almost immediately and produce no alcohol/CO2. Relevant? No fuckin idea. Lemme know if you end up exploring this further and find some knowledge

Your reverse engineering is legendary. For scraping off the silicone coating, try wetting it with isopropyl alcohol and use a soft wooden scraper stick. This works wonders the times I tried it. Not being a drinker myself, when I do break down and "have one for the cause", I almost always choose a dark ale. Yummy.

[@xAlexZifko]

Im gonna spice this suggestion up a bit. Instead of isopropyl use ghb/gbl/1,4 BDO (in order of favor, and depending on legality in your area) which are all highly effective plasticizers and solvents. Should scrape like butter

We used to have a similar thing to this where I used to work - we had to have specific cans of Guinness for it, and you placed the glass on a small metal plate which vibrated ultrasonically.

Someone's in a cheeky mood. You got an eyeroll out of me with that "nice, creamy head." So my question is, what have people who drank Guinness from bottles been experiencing all this time?

[@mattgayda2840]

There's a difference between carbonization and nitrogenation, most of the Guinness is carbonated unless it specifically states it's nitrogen. There's a huge flavor difference between nitrogen and carbon dioxide and if you find somewhere with side by side taps of the same beer to taste test it's blatantly obvious. CO2 adds bitterness so using nitrogen on a stout means it's sweeter and tastes completely different.

[@VeganAtheistWeirdo]

@@mattgayda2840 Thanks. That probably explains why people have such drastically opposing opinions on the stuff, more so than beer it seems. Would the same be true for other -lagers- stouts?

But, the one time I tried it, I cracked it and drank straight from the can before I even noticed the instructions. By the time I did pour it into a glass, I think what little gas was left escaped after the rough pour and it went flat really quick because it just tasted like flat Pepsi and I wasn’t impressed.

I think the price will come down when the novelty wears off. There's a trick to open the widget cans without triggering them by tapping a pin through the top and letting the pressure bleed off slowly. Then the can can be used with the surger.

Nice tip BC thank you

Nitro Monster energy drinks and Nitro cold coffee would be interesting to test! Nitrogen is used in a lot of food packaging like crisp packets as it's relatively inert, keeps things fresh, and makes up ~78% of air! 🤓

Thanks, ChatGPT - definitively, certainly (may in fact be completely incorrect): The PIC16F1824 is a low-power 8-bit microcontroller with 14 pins and operates on a 3.3V supply voltage. Pin 2 is VCC and pin 6 is GND, which matches the pinout configuration you mentioned.

[@bigclivedotcom]

The power pins do not match the PIC16F1824 (pin 1 + and pin 14 -). But I bet it made the statement with its usual pompous authority.

_"Creamy head"_

[@conradhardman7254]

That's what she said 😂

2:11 "mmmmm, creamy head"... Even though Guinness is my favorite stout, aftter hearing that description Guinness will never get anywhere near my mouth again. Lol.

This is a marketing campaign if I’ve ever seen one. I assume the consumer would purchase this device. This will reinforce regular purchasing the beer and build loyalty. This purchasing of the device gives the manufacturer data of the users to market too ongoing. It’s a nice looking unit befitting a luxury brand. This companies portfolio is primarily the premium end of the market. I nearly went to work for them in Australia in a senior management role. However decided to stay within food manufacturing sector. They are an excellent business.

The Bear Brotherhood flag caught me off guard. I only watch your teardown content and this is my first time seeing what you look like. A surprise to be sure, but a welcome one. Cheers.

Great video as always, bit disappointed they used a red LED rather than a green one

[@peterfitzpatrick7032]

Maybe they shoulda used a black one , Craig !! 🙄😂

I suddenly have the urge to buy something I didn't know existed 18 minutes and 51 seconds ago.

[@DairyAir]

“Creamy head” made me grin, but “liberating gas” made me laugh🤣🤣🤣

[@BenderTheOffender]

I came for the velvety texture, but I stayed for the schematics!

[@Roll-Penut]

I forgot big Clive looked like that and when I heard his voice I was caught completely off guard

[@brisingrprotogen1739]

"mmm, creamy head" ya know, if i hadnt seen the bear flag in the corner earlier, i would've questioned that little joke
