The curated and exclusive menu features new craft cocktails and a series of 'rituals' available only on board Celebrity.
Among them is Mystic Ketel One, a tropical cocktail is made with Ketel One vodka. A specially designed kettle cools the mixture of strawberries, pineapple, aloe vera, lime juice, ginger liqueur and Ketel One and releases a vapor.
For Zacapa Old Fashioned, Zacapa 23 rum is mixed with Angostura bitters and a dash of chocolate mole for a twist on one of the classics.
Celebrity No. Ten is a refreshing cocktail made with Tanqueray No. Ten gin, fresh raspberries, a dash of bitters, lemon juice and creme de violette and topped off with ginger ale.
The World Class Bar will soon roll out to the other four Solstice-class ships.
The bar will provide exceptional drinking experiences, according to Doug Bagley, managing director, Diageo Global Travel and Middle East.
'It brings to life our World Class ambition to inspire the world to drink better through innovations such as unique ritual serves, and it represents a bold approach to growing the fine-drinking category,' he added.
Since 2009, more than 15,000 bartenders have been educated by World Class, and each year the Diageo World Class Bartender of the Year competition showcases some of the industry's best talent.
