The matte black milk jug from Rhinowares is made of stainless steel and coated with Teflon. It has a wall thickness of 1 mm, which is slightly thicker compared to cheaper milk jugs. This gives it a pleasantly heavy feel in the hand, and it allows for a bit more time when frothing milk, as the walls heat up more slowly and keep the milk cooler for longer. The shape of the jug is designed to allow the milk to circulate well and create fine microfoam. However, frothing milk is not entirely easy and requires practice. Therefore, it may happen that larger air bubbles form in the milk. You can usually remove the largest milk bubbles by tapping the milk jug on the tabletop. The slightly concave spout ensures a straight and controlled stream of milk, making it easier to pour and create latte art. The barista milk jug is available in two different sizes: 360 ml and 600 ml, as well as in three different colors: blue, black, and stainless steel version. Unlike the stainless steel version, the blue and black jugs do not have a measuring indicator on the inner walls. The correct ratio of milk volume to milk jug volume is very important. If the measuring indicator is missing, you can still find the right amount by filling the jug with milk up to just below the lower edge of the spout. It is not recommended to wash the jug in the dishwasher. It is best to clean it with hot water and mild soap.
