How to distinguish countable and uncountable nouns

There are some obvious ones like 'apple' and 'water', but how can I distinguish nouns like 'experience'? I just learned that 'experience' can be both countable and uncountable depending on the context. There are numerous other examples that I can't determine whether it's countable or not... and most of them can be both countable and uncountable so it's adding my confusion. Is there any way to easily determine whether a noun is countable or uncountable?
