Water bottles are the very first step to creating potions. Glass bottles are filled by right clicking either a water source block or a filled couldron while holding a glass bottle.
Note that glass bottles can stack, but water bottles can’t.

Cauldrons only allow for up to 3 glass bottles to be filled, but a water source block will allow for an infinite number of glass bottles to be filled, so using a water source block is always faster and more efficient.

Up to 3 bottles can be placed in a brewing stand and it’s advised you do so. A single ingredient will be spread over all 3 potions, so it’s a lot more economic to use 1 ingredient on 3 potions instead of just 1 or 2.
