Today, iced milk tea is usually prepared with ice cubes. However, in the old days, when machines for producing ice cubes were not popular, the iced milk tea was made by filling the hot milk tea into a glass bottle and then cooling it in a fridge. Sometimes the milk tea were filled in Vitasoy or Coca-Cola bottles, and were sold by bottle. Today this type of "bottle milk tea" is rare in Hong Kong. Iced milk tea in cans or plastic bottles can be found in many of the convenience stores around Hong Kong such as 7-Eleven and Circle K.
