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
