Sometimes you just fancy one glass of wine, but don't want to waste the rest of the bottle. The V Gauge is the wine stopper that puts an end to waste. What makes it stand out from other wine stoppers is that it has its own built-in pressure gauge. 'Why on earth do you need a gauge?' we hear you cry. Most wine stoppers work just fine, but they all have one fatal flaw - when the vacuum deteriorates oxygen seeps into the wine and before you know it your bottle of plonk has magically transformed into vinegar. The V Gauge is quite staggeringly simple to use (we bought a bottle of wine in the interest of "research" to test it out) - you just pop it in the top of the bottle, pump out the air with the vacuum pump (included) and watch the needle on the gauge swing into the red. Once it's there you can stop pumping knowing that the there's enough of a vacuum to keep your wine fresh for ages. The best part is that you'll be able to see when the vacuum needs to be topped up as the needle will start dropping out of the red.There's no greater sin than wasted wine so keep your vino fresh with the V Gauge.
