UK supplier Enotrade (enotrade.co.uk) will sell or lease the machines to retailers. The company is a bit cagey about its pricing structure but you can expect to pay something like £5,000 for an eight-bottle version which will keep wines in perfect condition almost indefinitely once open. The system uses nitrogen to create a seal that prevents oxygen from doing the damage we all know itís capable of.
Some retailers sell credits that allow customers to wander around a whole battery of Enomatic machines and taste to their heartís content, so they create a direct revenue stream. But itís more common for shops to use them as a way of encouraging sampling. Not only does this promote your more expensive wines, but it saves the wastage invariably involved in opening a series of bottles.
