Root beer is a beer brewed with malt and sugar, usually from malt and wheat.
It’s the only type of beer brewed in the UK, but it’s popular around the world.
It is often drunk in the winter months to get the right flavour, but also to make you feel relaxed, and for some it can help to boost moods.
It can also be used as a remedy for a variety of illnesses, such as colds and flu.
There are different kinds of root beer depending on where it is made, and you can even get a different flavour depending on the location.
A pint of rootbeer will typically contain around 50-70ml of the liquid.
