I can’t quite tell if this interesting idea would actually work or not, but it’s certainly piqued my interest. The idea in a nutshell is a glass with “raised ribs set parallel apart in a spiral pattern that extends down the interior surface.” According to the inventor, “the spiral pattern of the ribs ensures that any fluid poured down the inside surface of the glass swirls around, oxygenating the beverage and releasing trapped carbon dioxide in the process.” He further indicates swirling it around will release more CO2, “while at the same time enhancing the aromatic attributes of the beverage.” My only real critiscm of the idea is that it would break up the view, so to speak. Because of the ribbed lines, you wouldn’t get a clear view of the beautiful color that beer often exhibits, but that may be small price to pay if it works well. Who knows? You can also download a pdf of the patent data which has more detailed information and diagrams.
