Grate the cucumber using a box grater and place it in a fine-mesh sieve or cheesecloth. Squeeze out excess moisture from the cucumber.
In a bowl, combine the grated cucumber, Greek yogurt, minced garlic, chopped dill, extra-virgin olive oil, and white wine vinegar.
Mix the ingredients thoroughly until well combined.
Season the Tzatziki with salt and pepper to taste. Adjust the seasoning according to your preference.
Cover the bowl and refrigerate the Tzatziki for at least 30 minutes to allow the flavors to meld.
Before serving, drizzle a bit of olive oil on top and garnish with additional fresh dill if desired.
