Don Julio is an upmarket tequila that, like most tequilas, comes from Mexico. It costs around $100 a bottle and is best enjoyed straight, unsullied by things such as salt, lime or other mixers. It is smooth enough to drink from a shot glass without the typical salt and lime, and it can also be used in a variety of cocktails, such as margaritas, mojitos and tonics.
While the bottle looks complicated, it is actually easy to open.
Twist the wooden ball of wood until it comes off. It is mounted on the bottle just like a standard cap.
Twist the plastic screw cap underneath the ball of wood until it comes off.
Open the valve, if there is one, by twisting it like a water tap. These are only present on bottles of Don Julio purchased in Mexico, and they do not come off. Rather, you just open it and pour the tequila through it.
