Place the yogurt in a bowl. Grate the cucumber and squeeze the grated cucumber with your hand to remove some of the liquid. Add the cucumber pulp to the yogurt along with the sour cream, lemon juice and zest, vinegar, dill, garlic, sea salt and freshly cracked pepper, to taste; stir. Place into the refrigerator for at least 30 minutes prior to serving so flavors have time to mingle. Enjoy.
