Many cocktails are sweet so that it would hide some of the strong alcoholic taste. These sweet cocktails usually are citrus in nature. That means they have at least one fruit in them or fruit flavoring of some sort. This all depends upon the bartender. If the bartender uses more fruit flavoring than alcohol, then that will make the drink even sweeter.
Some of these sweet cocktails include Daiquiris, an Old fashioned, Martinis and Bloody Marys. Many sweet drinks appeal to women, so bartenders will offer those drink to the girls that come into their bar. Another sweet cocktail is called the Sangria. It consists of red wine, sprite, brandy and fruits. This is mixed together and presented to the customer to drink.
