Hario Heatproof Glass Barrel

This barrel-shaped glass is perfect for your alcoholic drinks as well as hot drinks.

The contents of a 500mL beer can fit perfectly in this glass mug; with the liquid up to the second line from the top, you have a perfect 7:3 beer to foam ratio.

The lines are also great for mixing other drinks; fill the glass with ice cubes, then add your base drink up to the second line from the bottom. Then add water up to the top line for a 1:3 ratio.
