Answer 1

this is due to the sense of taste
it is pretty likely that we know that lemon tastes sour and bitter gourd tastes bitter

Answer 2

We could identify the drink with the help of taste, despite being blindfolded. Tongue is the organ that makes us feel the taste. Different buds of the taste contain the cell of the test receptor, also known in tongue as gustatory cells. The sweet taste buds are on the tip of the tongue, salt taste buds are on both edges of the front tongue, sour taste buds are behind it and bitter taste buds are in the back.
