Ruby Red Grapefruit Cosmo

No one has ever turned down my ruby red grapefruit cosmo cocktail. No one! Why? Because the full body of the grapefruit juice combines so nicely with the premium alcohol.

I’ve made these cosmos two different ways. I’ve made them with freshly squeezed grapefruit juice and I’ve made them with store bought juice. Which do I prefer? You may be surprised but I’m going to say store bought.

I know, I know. I’m usually into freshly squeezed, but when I usually serve this ruby red grapefruit cosmo, it is at a dinner party and I want to enjoy my party and I don’t want to be manually squeezing grapefruits all evening. Not only is it time consuming, but it’s costly.

Helpful tips

  • If you are going to squeeze your own, make sure you use ruby red grapefruit
  • Slice the garnish different ways, experiment with a grapefruit wheel, a wedge or a chunk.  You can also use two wheels as that makes for a pretty drink
  • If you can’t afford premium ingredients, it’s okay to use mid-level as with the robust flavor of the grapefruit, you won’t notice the difference as much
  • Shake vigorously so the ice breaks off in slivers.  There is nothing like little ice chips floating in your drink

  1. Love it! And I have all the ingredients in my kitchen, result! Will make this at the weekend and get back to you ๐Ÿ˜‰

  2. Mmm, just pinned this and can’t wait to make one next weekend. I love grapefruit and I love cocktails, so this is right up my alley.

    1. Yay. I love it and so don’t my guests :). Remember, if the drink isn’t sweet enough for your taste, you can add some simple syrup. Let me know how they came out!

  3. This looks incredible! I love grapefruit. I can’t wait to try it. If only I had a freezer big enough for me to store cocktail glasses in!

  4. I am not a grapefruit fan, per se. BUT I can get excited a good grapefruit cocktail! And I am a martini lover in general. Going to try this!

  5. I love how you can make a drink like this at home and not spend a ton of money at some overpriced bar. This would be great to make for a girls night in.

    1. Kara, I got both of the glasses from Crate and Barrel. The one with the big base is more expensive than the other! I love them both and actually have another martini glass from C & B that I have that I use a lot!

    1. For this one, I would do a sugar rim, but I usually don’t garnish the rim. But I know people have used colored sugar before. Thanks for your question Kelly! Cheers.
