The question is not only how many people will sit down. It also matters whether the caviar is a first taste, one appetiser among several or the centre of the meal. There is no compulsory portion for every occasion. Start with the tin's net weight and divide it by the number of people who will actually try it; then adjust for the role you want it to play.
The useful calculation takes one line
Divide the grams in the tin by the number of guests to get grams per person. A 10 g tin shared by two gives each person 5 g: a brief introduction. A 50 g tin for two offers 25 g each, allowing a more leisurely tasting. Share 125 g among five and you again have 25 g each. These are examples of division, not rules about how much anyone should eat.
If the caviar accompanies a generous menu, you may want to serve less per person and let other dishes take the lead. If it is the reason for gathering, a larger amount leaves room for a first spoonful on its own and a second with a simple accompaniment. Consider whether some guests may prefer not to try it.
Guest count is not the whole answer
Two tables of six can need different amounts. At one, caviar opens dinner for a few minutes; at the other, it is served slowly and discussed across several tastes. Write down the number of people, caviar's place in the menu and when it will be served before choosing a weight. That small step helps avoid both a tin that feels insufficient and an amount you cannot comfortably enjoy.
For a long gathering or guests arriving at different times, several small tins may be more practical than opening one large tin early. Confirm availability and sizes before committing to a menu, and always follow the pack's instructions after opening.
Tin, gift box and service are different choices
An individual tin contains the stated weight of caviar. A gift box adds presentation and the accessories listed on its product page; it does not increase the weight inside the tin. For a gift, check the exact contents. For an event, discuss quantity and conditions with the team rather than simply scaling up a calculation meant for a home table.
Delivery belongs in the calculation too
Finally, plan delivery and refrigeration. A number that works on paper matters only if the tin arrives when needed and is kept as the label instructs. The right size is one you can receive, keep cold, open at the right moment and share without rushing.
