Glassware
The shape of a wineglass can have a subtle impact on the perception of wine, especially its bouquet. Typically, the ideal shape is considered to be wider toward the bottom, with a narrower aperture at the top (tulip or egg shaped). Glasses which are widest at the top are considered the least ideal. Many wine tastings use ISO XL5 glasses, which are "egg"-shaped. Interestingly, the effect of glass shape does not appear to be related to whether the glass is pleasing to look at.
