For other people who are not accustomed to the delicacy we call caviar, all these things taste and cost the same.
But that is not the case. Like any other thing, there is a hierarchy in the realm of caviars in the form of caviar grades. It is noteworthy to state that the grading is a unique feature of caviars originating from Iran and it can only be done by an expert caviar processor. (To become an expert in caviar-making, it takes 10 to 15 years of apprenticeship under strict supervision.)
But now, here is a chance to know basic things about caviar rating by keeping in mind the following facts and guidelines.
The Factors In Rating Caviars:
A lot of factors are involved in grading caviars. Such factors are as follows:
Egg Uniformity
This refers to the general appearance of the caviar. Generally, a good kind of caviar has consistency when it comes to egg characteristics such as color, size, etc. This factor takes into consideration the precise grouping of eggs in caviar making.
Egg Size
Depending on the sturgeon kind from which the eggs came from, caviars have corresponding sizes. For example, Beluga caviars must have grains the size of a pea. If the eggs fit the expected egg size, it only means that the eggs used are mature and fit for caviar making.
Egg Color
Egg color determines the quality of the caviar. Eggs vary in color, depending on the age of the sturgeons from which it came from. In the case of Osetra caviars, the color of the egg faints (from dark grey to golden brown) as the sturgeon fish matures.
Egg Maturity
Caviars taste better when they are processed in their prime age. The best quality Sevruga caviars are processed from roe which came from Stellate sturgeons within 18 to 22 years old.
Separation Of Egg Grains
The egg separation has something to do with the way the eggs have been processed. It answers how delicate the process of sieving took place as well as the equipment used in doing so.
