## The Inevitable Question You've got a Nitrosurge device but can't find Nitrosurge cans anywhere. Or maybe you've got regular Guinness Draught cans in the fridge and you're curious. Either way, you're wondering: "Can I just use regular widget cans with my Nitrosurge?" We tried it at home. What follows is informal, unmeasured experience, not a controlled test. ## Why This Matters Nitrosurge cans can be harder to find than regular Guinness Draught. Many shops stock the widget cans but not the Nitrosurge-specific ones. If you own the device, you want to use it - even when proper cans aren't available. ## The Theory Regular Guinness Draught cans contain a plastic widget that releases nitrogen when you open the can. The pressure drop triggers the widget to shoot nitrogen through the beer. Nitrosurge cans have no widget. They're designed so the Nitrosurge device does all the nitrogen activation via ultrasonic technology during the pour. Using regular cans with Nitrosurge means double activation: 1. The widget activates when you open the can 2. The Nitrosurge activates as you pour In theory, this could either enhance the effect, do nothing useful, or cause problems. ## What We Tried At home, with fridge-cold cans, the same glasses and a charged device, we compared: - Nitrosurge cans with the Nitrosurge device - Regular widget cans poured normally - Regular widget cans poured with the Nitrosurge attached We did not measure anything; these are our impressions. ## What Happened ### Regular Can + Nitrosurge **What Happened:** When we attached the Nitrosurge to a regular widget can and poured, we saw: - Significant over-foaming - Excessive head that collapsed quickly - Thinner body than normal - Wasted beer from overflow The Nitrosurge on regular widget cans produces too much foam. The widget has already broken out the gas, and the Nitrosurge releases even more. The result is a glass of mostly collapsed foam and a thinner, flatter pint. ### Our Impressions | Method | Cascade | Head | Body | |--------|---------|------|------| | Nitrosurge can + Nitrosurge | Excellent | Excellent | Full | | Regular can + Nitrosurge | Poor | Over-foamed | Thin | | Regular can alone | Good | Good | Normal | ### Key Findings 1. **Worse than doing nothing**: in our experience, using regular cans with Nitrosurge makes the pint worse 2. **Over-foaming is severe**: The dual activation releases too much gas 3. **Thin, flat result**: Once the foam settles, you're left with less creamy Guinness 4. **Not recommended**: The basic hack doesn't work with Nitrosurge ## The Needle Method (The Better Hack) If you're determined to use regular cans with your Nitrosurge, there's a workaround that actually produces good results: depressurise the can first to keep the widget dormant. ### The Theory The widget inside a Guinness can activates because of the sudden pressure drop when you open it. If you release the pressure slowly through a tiny hole first, the widget stays inactive. This leaves the beer in a state similar to Nitrosurge cans - ready for the device to handle all the nitrogen activation. ### What You Need - A clean sewing needle, thumbtack, or pin - Cold regular Guinness Draught cans (4°C or colder) - Your Nitrosurge device - Patience ### How To Do It Ensure the can is properly cold - at least 24 hours in the fridge. This is crucial for the hack to work safely. With the can upright, carefully pierce a tiny hole near the top of the can, just below the rim and above the liquid line. Use a sewing needle or thumbtack. You'll hear a gentle hiss as the pressure releases slowly. This should take 30-60 seconds. Do not rush this step. Keep the can upright until the hissing stops completely. The can is now depressurised and the widget should remain dormant. Open the can normally - you'll notice much less fizzing than usual. Attach your Nitrosurge device to the can opening. Press the Nitrosurge button and pour as you normally would. The device will create the surge effect, just as it would with proper Nitrosurge cans. Pierce the can while it's upright and very cold. Aim for the area just below the rim where there's air, not liquid. The gas will escape cleanly without any beer spraying out. ### Needle Method: Our Impressions | Method | Cascade | Head | Body | |--------|---------|------|------| | Nitrosurge can + Nitrosurge | Excellent | Excellent | Full | | Needle method + Nitrosurge | Very good | Very good | Full | | Regular can + Nitrosurge | Poor | Over-foamed | Thin | | Regular can alone | Good | Good | Normal | In our experience the needle method produces noticeably better results than the straight hack: a proper cascade, a creamy domed head and a smooth body. It's not quite as good as proper Nitrosurge cans, but it's close. Again, this is our impression from a few home pours, not a measurement. ### Why It Works By depressurising the can slowly, the widget never activates. The nitrogen stays dissolved in the beer, waiting for the Nitrosurge's ultrasonic technology to release it properly. You're essentially converting a widget can into a Nitrosurge can. This method involves sharp objects and pressurised cans. Take care when piercing. Never attempt this with a warm or shaken can - the pressure will be higher and the gas will escape violently. Always keep the can upright when piercing. ## Tips for Success ### Temperature Is Critical - Colder is better for the needle method - Warm cans have higher pressure and are riskier to pierce - A properly cold can (3-5°C) will depressurise gently ### Pierce in the Right Spot - Aim for the very top of the can, just below the rim - Pierce above the liquid line (the can isn't completely full) - Keep the can perfectly upright during piercing ### Don't Rush - Let all the gas escape before opening - A rushed job means the widget might partially activate - 60 seconds of patience saves your pint ## Should You Try It? ### Yes, if: - You already own a Nitrosurge - You can't find Nitrosurge cans in your area - You're comfortable with the needle technique - You want near-Nitrosurge results from regular cans ### No, if: - You're buying a Nitrosurge specifically for this hack - You're not comfortable piercing pressurised cans - You expect identical results to proper Nitrosurge cans - Regular widget pours satisfy you The needle method takes extra effort, but it has worked for us. If Nitrosurge cans are unavailable in your area, it makes owning the device more useful. ## The Verdict **Does using regular cans work?** Not in our experience - the basic approach makes things worse. **Does the needle method work?** For us, yes - with noticeably better results. **Is it worth it?** If you can't get Nitrosurge cans, the needle method is your best option for using the device. **Recommendation:** Never use regular widget cans directly with Nitrosurge - you'll get a thin, over-foamed mess. If you want to use regular cans, the needle method is essential. It adds 60-90 seconds to your prep time but delivers results close to proper Nitrosurge cans. ## Alternatives to Consider If this all seems like too much effort: 1. **Order Nitrosurge cans online** - Often available even when local shops don't stock them 2. **Master the widget pour** - Regular cans with good technique produce a great pint 3. **Visit a pub** - sometimes fresh draft is worth the trip; browse the [community-rated Guinness pubs near you](/pubs-near-me) --- Want to learn the proper Nitrosurge technique?
