Why wine tastes more bitter as meal progresses

[sanjay_111]

Hi, I am pretty much a novice in wine drinking. Actually, I had never liked any alcoholic drinks earlier primarily because of the smell. But one day someone actually practically forced a Chardonnay on me and I just loved it. Since then I take wine regularly.

I seem to like sweet wines rather than dry and bitter. I also find (and this is my question), that wine tastes more and more bitter as the meal progresses. Anyone can tell me why it happens. For information, I invariably take very spicy Indian vegetarian food.
