. It says 16 gotas so what is a gota  ?

A gota is a drop, una gota. Examples, gotas de lluvia - rain drops, gotas para ojos - eye drops.

There is also a saying when just a few drops of rain have fallen - 'Ni ha caido cuatro gotas' - barely 4 drops have fallen.

Also another saying when you only want a small amount of wine is 'Dame una gota de vino' or alternatively, 'Un dedo de vino' - a finger (thickness) of wine.
