When it comes to hot drinks, such as hot chocolate or coffee, there are a number of options for cups. Glass cups for hot drinks are the picks for a lot of people, and it mostly comes down to it being the most environmentally friendly.
Glass is something that can be recycled, while ceramic can’t. This is the main reason why a lot people will end up going with glass. There are also certain designs that are just better overall with a glass cup, so that is something for people to keep in mind as well.
As far as taste is concerned, there really is no difference with a glass cup compared to something else. Just know that if you want to be the most environmentally friendly person out there, a glass cup is probably better for any type of warm drink.
