![]() And the vacuum process itself can pull some character out of the wine.Įto bills their device as more than just a non-oxidizing storage vessel. With those, the wine fades noticeably after a week or so. (I didn’t try the bottles without refrigerating, nor with aged wine, but will do so in the coming months and post an update.) The eto performance is much better than the vacuum wine preservers I’ve tried. There was no decline, or even change, in the wines’ color, aroma, or flavor after three weeks. I repeated this after two weeks and after three weeks. ![]() After a week, I took a partial glass from each and took notes again. Then, I put them into the decanters, pushed out the air, and refrigerated them. I tried a glass of each wine upon first opening and took notes. I intentionally chose wines which would be susceptible to oxidation-low acid in the case of the white, moderate tannin and low acid for the red. To test the devices, I tried the silver one with a white wine and the copper one with a red. But both tasks are doable and those tight fits are what makes the product work. It can also be difficult to get the plunger/gasket back into the bottle. I sometimes found it challenging to get the top to unscrew from the glass bottle. The whole thing, including all the gaskets, comes apart for cleaning. Various parts of the assembly include rubber gaskets to ensure tight seals. The tube serves as both pouring spout and plunger handle. Within the top piece is a telescoping tube, a little more than an inch in diameter. The tops come in two colors, silver and copper. The top of the decanter, which screws onto the glass portion, is highly polished metal. The main part of the bottle-they call it a decanter-is high-quality glass. Numerous, minute adjustments to design and tooling took place over nearly two years.įortunately, based on my testing, the product works very well now. Getting very tight tolerances, especially with glass, is quite difficult. There are a lot of parts which need to mate together perfectly and several moving parts as well. The product is necessarily much more complicated than a simple bottle and plunger. It was that need to be absolutely air-tight which led to the long delay in product availability. It either prevents oxidation or it doesn’t. Even a tiny air gap would make such a product useless. With no wine-air contact, oxidation should be virtually nil. ![]() There’s a plunger in the top, which, when pressed down, forces all air out of the bottle until the plunger actually makes contact with the wine. eto is essentially a bottle which holds 750ml of wine. ![]() What would my experience be with more rigorous testing of a near-production model? What is eto? Richard Hemming MW, of, tested an early prototype for a week and found the wine didn’t change perceptibly over that period of time. The eto decanter received a reddot award for design in 2018. After various delays due to multiple rounds of tweaks to the materials and tooling, the product finally arrived from the producer, eto, three weeks ago. The idea was similar to one I’d had myself previously, a wine-preservation device that does the job entirely mechanically-no gas, no vacuum. Almost two years ago, I took a flyer on a crowd-funded, product in development.
