An important part of decanting red wine is ensuring sediment stays in the bottle. This is best achieved by visually tracking the sediment particles as wine is poured and ceasing the decanting at the right time. This is a far better method than trying to filter the sediment which can still find its way into the decanter or wineglass. Wine professionals and enthusiasts know this, but until now have not had an easy and reliable way to illuminate the bottle while pouring to spot the sediment. POURVIN Light is the new elegant solution; it fits over the neck of the bottle and shines a precise light exactly where it is needed. With the sediment clearly visible it takes the guesswork out of decanting.
