Scientists at Brandeis University in Massachusetts have developed a wine bottle that doesn¡¯t drip when poured.
Can¡¯t find your foil wine pourers? Don¡¯t worry. Scientists have created a wine bottle with a diamond-cut groove below the lip that guarantees a drip-free pour.
Constant bottle-neck wiping could be a thing of the past!
Glass is a hydrophilic material, in other words, water molecules are attracted to it. After studying slow motion videos, Dr Dan Perlman, the creator of the drip-free bottle, discovered that when poured, wine tends to curl backwards over the lip and run down the side of the bottle. The groove prevents this from happening ¨C the wine can¡¯t travel over it and instead falls straight into the waiting glass.
Dr Perlman, a biophysicist at Brandeis University and a keen oenophile, said that he ¡°wanted to change the wine bottle itself.¡±
¡°I didn¡¯t want there to be the additional cost or inconvenience of buying an accessory,¡± he added.
Working with engineer Dr Greg Widberg, Dr Perlman hit upon the ideal width (0.2cm) and depth (0.1cm) for the indentation to ensure a clean pour.
Wine enthusiasts have previously relied on foil pourers and other gadgets to protect their tablecloths.
In a statement, the university explained the new feature, ¡°A droplet of wine that would otherwise run down the side of the bottle encounters the groove, but can¡¯t traverse it. Instead, it immediately falls off the bottle into the glass along with the rest of the wine¡for a drop of wine to make it across Perlman¡¯s groove, it would have to travel up inside the groove against the force of gravity or have enough momentum to jump from one side of the groove to the other.¡±
Dr Perlman is a prolific inventor, holding over 100 patents and most recently developing coffee flour, an ingredient and nutritional supplement made from par-baked coffee beans.
