The grapefruit juice goes well with the ginger and the smoothness of the whiskey.

This drink would be perfect for St. Patrick’s Day, obviously, but I feel like the grapefruit just adds an extra summery element to it, I don’t know. Yes, grapefruit is technically a winter citrus, but citrus in general just feels like summer to me. Perfect for sipping on a hot day!

The temperatures have finally started rising here, and I’ve got drinks and picnic food on my brain. 🙂

How did this idea come about? Well, my friend Meghan at Fox and Briar is the queen of Irish Mule recipes. I don’t make cocktails too often, but whenever I see her photos, that drink just looks so refreshing, and I had to try it myself. I finally picked up some copper mugs, and I gave the Irish Mule my own little twist.

What’s in an Irish Mule?

An Irish Mule is similar to a Moscow Mule, but instead of vodka, Irish whiskey is used. An Irish Mule contains whiskey, ginger beer, and lime juice. In this case, I replaced the lime juice with grapefruit juice to make a grapefruit Irish mule cocktail.

How do you make an Irish Mule?

Add ice to your glass (preferably a copper mug). Pour in the whiskey and fresh grapefruit juice. Top up with ginger beer. Garnish with grapefruit wedges if desired.
