I would like a cool summer cocktail that is strong (alcohol content) but also has little alcohol taste.

If you're seeking a summer cocktail that's cool and refreshing but packs a punch without an overpowering alcohol taste, let me guide you to some excellent choices.

One great candidate is the Summer Rain. This cocktail combines coconut rum and vodka, providing a substantial alcohol content of 40% in a 120ml serving. Despite its strength, the coconut rum's sweet and exotic flavors help mask the robust presence of vodka, making it a spirited yet smooth option that's perfect for a warm day.

Another strong but palatable option is Summertime. This drink blends dark rum and Drambuie with soda water to yield a total volume of 120ml and an alcohol content of 20%. The dark rum offers a rich, molasses-like sweetness, while Drambuie adds honey and herbal notes. The splash of soda water lightens it up, ensuring that the drink remains refreshing without the alcohol becoming too pronounced.

Both of these cocktails achieve a balance between strength and drinkability, making them ideal choices for enjoying the summer sun while keeping things breezy and flavorful.
