I want cocktails to order at a bar that are sour/tart and have no alcohol taste. No pineapple or coconut.

It sounds like you're looking for cocktails that offer a refreshing, sour/tart experience while masking the alcohol taste. Fortunately, there are some fantastic options on the list provided that fit these criteria well and will be perfect for your next trip to the bar.

Firstly, the Sour Apple Martini (Rated 4.22/5) should be a top choice. It combines lime juice, vodka, sugar syrup, and apple schnapps to create a vibrant and tangy drink. The apple schnapps and lime juice work wonderfully together to mask the alcohol, presenting a refreshingly sharp and sophisticated cocktail. It's often served chilled with a garnish of apple slices, adding to its fruity appeal.

Another excellent option is the Tartini (Rated 4.4/5). This cocktail blends cranberry juice and vodka with fresh raspberries for a tart and slightly sweet beverage. Despite the vodka, the combination of fruit juices makes it a flavorful choice that masks much of the alcohol taste effectively. It's also been featured in pop culture, such as in "Sex and the City," which adds a fun twist to ordering it at a bar.

Additionally, the Bakewell Tart (Rated 3.7/5) aligns quite well with what you're looking for. Inspired by the classic British dessert, it features lime juice, cranberry juice, lime cordial, amaretto, and grenadine. This cocktail offers a sweet and tart flavor profile where the nutty undertones of the amaretto and the tanginess of the lime and cranberry juices thoroughly mask the alcohol content. The result is a flavorful, refreshing drink reminiscent of a fruity dessert.

Lastly, for something a bit different, you might enjoy the Double Sour, Apple-lemon Martini (Rated 3.63/5). This drink combines the sharp zest of lemon juice with the tart sweetness of apple schnapps and a smooth vodka base. The strong citrus and apple flavors ensure the alcohol taste is significantly masked, making it a tart yet refreshing choice.

Give these a try next time you’re at the bar, and you’re sure to enjoy a delightful, sour/tart cocktail experience without the overwhelming taste of alcohol!
