How is caviar harvested

This allows sturgeon farmers to reuse the same fish to harvest roe multiple times during their expected to year lifetime. The extracted eggs are then put through a calcium-water solution to prepare them to be salted and packed for consumption. They produced 1, pounds in Evans tried to extract caviar without killing the fish, but found it was too soft. There is currently one available variety of Vivace, including caviar taken from Siberian sturgeon Acipenser baerii. There is only one, with the possibility of more in the future.

After they have been washed and drained, they are graded according to quality. This is judged by the firmness, colour, smell and taste of the grains.

The caviar is then salted to improve its taste and enable it to be preserved for longer. The salt is thoroughly mixed with the grains of caviar, but only briefly, so that they retain their firmness. The caviar is then placed on a sieve to dry.

The caviar is then quickly canned to stop it collapsing. The grains are packaged in metal tins and sealed with an overlapping lid to let as much air out as possible. Those due to be exported generally weigh 1.

They are then re-packaged in smaller tins by retailers. The tins are transported in refrigerated lorries. Small amounts are sometimes shipped by air freight. Caviar tastes somewhat like egg yolk, with a touch of herbs and iodine. Some varieties may be reminiscent of hazelnuts.

Caviar has a recognisable sweet, fresh smell. To release its delicate flavour , you pop the grains of caviar against the roof of your mouth with your tongue. Eating it with bland toast or blinis Russian pancakes made from yeast dough brings out its taste. However, it also contains borax, very fine salt used as a preservative. The same goes for taste.

As the fish get older, it could be that the eggs get larger. Each fish could have a different taste. As opposed to roe forced out of the fish, the eggs will be much softer, and so will need to be pasteurised and stabilised with added preservatives before they can be consumed. You might be wondering if it takes away anything from the eventual cost to you.

Of course, there are other sides to the argument. Exmoor Caviar in Devon has been producing roe for the past three years using traditional methods, supplying Michelin-starred restaurants wanting the finest caviar but with a more local appeal. Also, the final product is completely different and no-kill farms do not tell of the vast chemicals used to restructure the roe, which when dropped naturally by the sturgeon is ready to be fertilised and inedible in terms of what people expect from caviar.

So while buyers might not be any less out of pocket, they do now have a choice on how their caviar is harvested. Take a look at what's new and get inspired. Latest Recipes.
