Combine the vinegar and fresh berries and set aside for at least 20 minutes.
In a pitcher, combine lime juice, tequila and triple sec. Set aside until the fruit is ready.
Using a fine sieve, strain the liquid from the berries then discard the berries. Get as much liquid out as you can before discarding the fruit. Feel free to use a spoon to help crush the juice free but don't force solids through the strainer.
Pour directly into the pitcher and mix well.
Serve on the rocks in a salt rimmed glass with a lime or berry for garnish. Enjoy!
