Of course, you should remember that it loses all its qualities once opened. Color, flavor, texture, maturity are the marks that help you find out the quality of caviar. 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.
