Which fruit juice is considered classic for brunch cocktails?

Orange juice is considered a classic for brunch cocktails mainly due to its association with popular drinks such as mimosas and Bloody Marys. It has a bright, citrusy flavor that complements the savory and sweet elements often found in brunch menus. The refreshing taste of orange juice pairs well with sparkling wines, like Champagne or Prosecco, making it a popular choice for mixing.

Additionally, orange juice is widely recognized and widely used in cocktail recipes, enhancing its status as a brunch staple. Its vibrant color and fresh flavor profile help set the mood for a celebratory brunch atmosphere, making it the quintessential fruit juice for this occasion. Other juices, while certainly enjoyed, do not have the same level of iconic association with brunch cocktails that orange juice holds.
