Yes, Sangria is typically better the longer it sits because it allows the flavors of the fruit and wine to meld together and become more pronounced. As the fruit sits in the wine, it releases its juices and flavors, which then infuse into the wine mixture. This creates a more complex and rich flavor profile. However, it’s important to note that there is a limit to how long Sangria should be left to sit. After a certain point, the fruit can start to break down and make the Sangria overly mushy and unappetizing. Generally speaking, Sangria is best prepared a few hours before serving or overnight if necessary.
