Sangria cocktail with Cointreau liqueur

1. Pour purified water into a saucepan, add sugar to it and mix and put on fire. We prepare the syrup until all the sugar crystals dissolve, let it cool down.
2. Orange and lemon are washed and cut into thin slices. We transfer it to a jug and pour it with ready-made sugar syrup, add orange liqueur Cointreau. Now we put it in a cool place for a couple of hours. The drink should be saturated with the aroma of citrus fruits.
3. Add red wine and mix. Our drink is ready!
