What's abstract about 'drink'? Is language concrete?

Firstly, what do you understand by the terms abstract and concrete?

What I understand is that :

Abstract noun is one which we cannot see, touch, but we can feel that.

e.g. love, hope, sleep, honesty, bravery, etc.

Concrete noun is one which we can touch and can see.

e.g. book, pen, pencil, computer.

Right, well how do you see or touch 'language'? We don't- it's not the same as the printed words on the page. 'Drink' can be concrete, but it can also be abstract. Remember that many nouns can display more than one characteristic. Many uncountable nouns can also display countability, depending on how you use them:
A lot of coffee is grown in Brazil. (Uncountable, thinking of the substance in general)
I'd like two coffees and a water. (countable, thinking about cups of coffee)
The shop sells many different coffees (countable, thinking about different types, brands, etc)
The categories are very often not fixed, but can change when the nouns are used.
