A water jug isn't just for serving water. A clear glass jar filled with water, juice, wine, or any beverage is a practical way to serve drinks. Typical jug sizes are between 0.25 litre and 1.8 litre. However, manufacturers do make larger sizes to meet most needs.
A multipurpose jug may be clear, or see-through, or come in various colours with and without prints. For easy clean-up, choose a water jug that is dishwasher safe.
