When you open a bottle of wine oxygen mixes with air and starts oxidation. Too much oxidation ruins any wine. ETO's unique, patented preservation system creates a seal between the wine and the air, reducing your wine’s exposure to oxygen, slowing down the oxidation process and keeping its great taste for longer.

Sometimes the metal parts contract when they’re cold. Try rinsing your ETO in warm water, then dry and try again. There's no need to over-tighten the shoulder to the glass – it has no effect on the seal.

You can store a standard bottle of wine in ETO 750, that’s 750ml (25.4oz). The minimum is 6oz, equivalent to a medium glass. Or, that final glass.  

Our original eto, fully extended, can hold 22 oz of wine. That's a standard bottle, minus one glass. The minimum capacity is 6oz. We recommend opening a bottle, pouring yourself a glass, then decanting the rest into eto.

A full ETO is the same height as a bottle of wine, designed to slot vertically into a fridge door. It's best not to lay it flat, as the seal might not hold.

No, ETO should always be hand-washed, without dish soap. That's why it's so easy to take apart and put back together.

Wash ETO every time you empty it, by soaking it in warm water. No need for soap or detergent, which can affect the taste and aroma of your wine. If your ETO needs a deeper clean, use a soft brush and soak in a bicarbonate of soda solution for up to 24 hours..

Accidents happen, so spare parts for every ETO are available from the  Shop.
