Or maybe better – ‘sulfite removal’!
I had some PR puff about this, and normally I avoid gizmos such as this, like the plague, but as a former research chemist I was interested in what the process might be.
From the website and the linked Kickstarter page it probably works like an ion-exchange resin – i.e. similar in mode to the standard filter that you may use to make your water a little more palatable, assuming you live in a hard-water area; here in Europe Brita water filters are one of major brands.
If the video is anything to go by, the filter works amazingly fast – so I expect it’s a mock-up – but I’d be really interested to see how ‘selective’ this ‘solution’ is, or whether it neuters the wine in any way. I also expect some blockage (blinding) due to the sediment in older wines – but maybe sulfites are not an issue with older bottles, so (in this case) the gizmo isn’t required. I’d also be interested to know how much volume, and of what type of wine, is required to ‘exhaust’ a filter – for instance sweet wines have much more sulfite to preserve them.
A fair question, though, is ‘how many people are really affected by this?’ I’m aware, anecdotally, that many are, and particularly for those who drink white wines, though in today’s market for ‘healthy living’ I’m sure this has great potential for sales, regardless of whether they drink Richebourg, Sauternes or Yellow Tail. Let’s see.
I assume though, that the company won’t be using the following data in their marketing campaigns, much as I know some people also have problems with dried fruit!
