The most expensive is Beluga caviar which color is lighter and the eggs are larger. The caviar which price is lower has a bit less fishy flavor, its color is darker. Caviar is a great accompaniment to romantic dinner, along with Asti Champagne and good mood. If you're going to have one with the beloved person, have a good appetite and great evening. What can drive every gourmet mad? Of course, it's caviar.
