The glass has a long stem, a high-sided bowl, a narrow mouth, and a moderate capacity (of about 5 US fluid ounces (150 ml)). It is considered a more elegant alternative to the large wide-mouthed martini glasses that were popular in bars in the 1980s. The glass's tighter bowl and straighter sides hold in aromas better than the wider martini glasses, are more spill-resistant, and keep cocktails colder longer
