For the convenience of users, it is recommended to install a bottle with a handle on the machine. This bottle can be placed next to the machine and can be easily inserted for brewing. The handle makes it easier for users to pick up bottles, avoiding burns to fingers during the brewing process. Bottles can also be leak proof to avoid spillage or waste of water. A good choice is to use reusable bottles, which can reduce waste and be more environmentally friendly. In this way, users can not only have a more convenient brewing experience, but also enjoy drinks more happily while contributing to the environment.
