The amount of caviar per person will vary based on the type of caviar being served and the appetite of those being served.  For instance, an ounce of beluga caviar per person may be considered a generous portion when served with blinis and crème fraîche, while two ounces of osetra caviar per person may be more appropriate for a more luxurious occasion.  Additionally, any other accompaniments should be taken into consideration when determining the amount of caviar per person. If there are several dishes or snacks being served alongside it, such as smoked salmon and hors d'oeuvres, then one ounce per person may be sufficient.
