Refreshing Whisky Mule // The Cali MuleIt's very refreshing with loads of citrus and just the right amount of ginger beer, perfect for summer. The Kentucky Mule is a classic cocktail that's been around since the 1940's. This is our West coast take on a mule that includes some citrus, like oranges, similar to margaritas that are very popular on the West coast. This is a great summer drink that goes well with any outdoor or backyard event and is great with BBQ!
