This is a 300ml milk jug designed for making latte art, with a metallic gold finish. The jug has a tapered shape and a rounded spout, which allows for precise pouring control. In the coffee industry, milk jugs come in standard sizes such as 350ml, 600ml, and 900ml, but these are just rough indicators and not exact measurements.
This particular jug can hold approximately 300ml of milk when filled to the brim, and it is recommended to fill the milk up to the base of the pour spout before steaming.
