I am a colorless alcohol.
I am usually served in a small clay cup/glass.
I am neither had with rocks nor water. Just neat.
I am sipped and not gulped like a shot.
I am usually had with a few pieces of oranges on the side.
(Rajib’s note: I did not have oranges. So, watermelon it is).

What alcohol am I?

Hint: Rajib had this for the first time in his life today.
