2 ounces mezcal (I'm using Vida here. If you find the smokiness of the mezcal too overpowering, you can try half mezcal and half tequila.)
2 ounces good apple cider
Fresh ground nutmeg
Pinch sea salt
Fill a collins glass with crushed ice. In a mixing glass, mix mezcal with cider. Pour mixture into collings glass over ice. Top with ginger beer. Sprinkle with just a pinch of nutmeg and sea salt.
