As an expert sommelier and brewer, I can provide a detailed answer to your question about the difference between a sweet Old Fashioned and a sour Old Fashioned. These two variations of the classic cocktail have distinct flavor profiles that can be achieved through different ingredients and techniques.
A sweet Old Fashioned typically refers to a version of the cocktail that has a sweeter taste profile. To achieve this, bartenders often use 7-Up as a mixer. The addition of 7-Up brings a subtle sweetness to the drink, complementing the flavors of the base spirit, usually whiskey or bourbon. The carbonation from the 7-Up also adds a refreshing effervescence to the cocktail. This option is popular among those who prefer a sweeter and smoother drink.
On the other hand, a sour Old Fashioned has a tangy and tart flavor profile. This variation is achieved by using Squirt soda or pre-packaged sour mix as a mixer. Squirt soda has a citrusy and slightly bitter taste that adds a sour element to the cocktail. Alternatively, pre-packaged sour mix is a blend of citrus juices and sweeteners, providing a similar tangy flavor. The sour Old Fashioned is favored by those who enjoy a more acidic and zesty drink.
Another option is the “press” Old Fashioned, which is a combination of sweet and sour elements. It is made by mixing half 7-Up and half club soda. This variation offers a balanced flavor, combining the sweetness of 7-Up with the slight tartness of club soda. The “press” Old Fashioned is a popular choice for those who want a middle ground between the sweet and sour versions.
It's important to note that these variations may vary depending on personal preferences and regional differences. Bartenders often have their own twists on the classic Old Fashioned, utilizing different mixers and ingredients to create unique flavor profiles. Experimentation and creativity are key in the world of cocktail making.
In my personal experience, I have found that the choice between a sweet, sour, or press Old Fashioned often depends on the individual's taste preferences and the mood they are in. Sometimes, I crave a sweeter and smoother drink, opting for the sweet version. Other times, I enjoy the tanginess and refreshing kick of a sour Old Fashioned. The press Old Fashioned provides a nice middle ground when I can't decide between the two.
To summarize, the difference between a sweet and sour Old Fashioned lies in the choice of mixer used. Sweet versions typically incorporate 7-Up for a smoother and sweeter taste, while sour versions utilize Squirt soda or pre-packaged sour mix for a tangy and tart flavor profile. The press Old Fashioned combines the best of both worlds, offering a balanced option. Ultimately, the choice between these variations depends on personal preference and desired flavor experience.
