The OKA whiskey cups are a refreshingly designed set of tumblers made from wood as oppose to glass in the effort to enhancing the tasting experience. The use of the oak heightens the flavor profile of the liquor by using similar materials found in the barrels that whiskey is commonly brewed in.
The glasses are made from oakwood that has been carefully carved and charred on the inside to bring out the most potent notes of the liquor. The design as well as the execution was inspired by whiskey barrels. The wood naturally absorbs elements of the alcohol and gives the drinker a much more experiential flavor profile when they sip the drink. The wooden design also adds an element of rawness to the glass that is refreshingly natural.
