- Christmas or Festive Ale
(Some good ones include Sweetwater Festive Ale, Anchor Brewing Christmas Ale, Bell's Christmas Ale, Shiner Holiday Cheer, St. Bernardus Christmas Ale, & Great Lakes Brewing Christmas Ale. I prefer Sweetwater Festive Ale because it has a higher ABV and mixes nicely with Guinness.)
- Guinness Draught
(preferably in a can but the bottles work too)
- Fill a beer glass with 6-8 oz of the Ale. Pour the Guinness over the back of spoon to float the Guinness above the Ale, just like you would if you were making a black and tan. Be careful not to overflow the glass.
- Wait for the foam to settle and enjoy your Black Christmas!
