Cocktail cherries nowadays typically do contain alcohol, although the exact amount can vary depending on the brand and the specific product. In the past, maraschino cherries were made by macerating sour cherries in maraschino liqueur, which naturally imparted an alcoholic element to the preserved fruit. However, today's commercial cocktail cherries are usually preserved in a sugar syrup, with alcohol added to extend their shelf life and enhance their flavor.
As a sommelier and brewer, I have come across various types of cocktail cherries in my experience. Some brands use a combination of sugar syrup and alcohol, such as rum or bourbon, to preserve their cherries. This not only adds a boozy flavor to the fruit but also helps to preserve them for a longer period of time. The alcohol content in these cherries is typically relatively low, as they are intended to be used as a garnish rather than consumed in large quantities.
It's worth noting that there are also non-alcoholic cocktail cherries available for those who prefer to avoid alcohol altogether. These cherries are typically preserved solely in a sugar syrup without any added alcohol. They still provide a sweet and fruity element to drinks and desserts, but without the boozy kick.
In terms of taste, the addition of alcohol to cocktail cherries can enhance their flavor profile and add complexity. The choice of alcohol used can also impart specific notes and nuances to the cherries. For example, cherries preserved in bourbon may have a rich and smoky flavor, while those preserved in rum may have a hint of tropical sweetness. This can make a difference in the overall taste of a cocktail, as the cherry garnish can contribute to the overall balance and harmony of flavors.
