Q stands for:

The quality of caviar depends on the strain (species) of sturgeon, good breeding in pure water basins and perfectly mastered know-how in extracting and refining the roe. It’s the salting and maturing of caviars that makes all the difference.

Each caviar house has its own tastes and strives for perfection in the balance of flavors. This specific know-how and quest sets each brand apart, along with the love of the product!
