Almas or Golden Caviar. This is by far the rarest of all caviars and in the past was for the sole consumption of the Tzars of Russia or the holder of the Peacock throne in Persia. These eggs either come from the albino sturgeon or those of an Oscietre sturgeon, which is at least 60 years of age. The taste of these eggs are, respectively light and delicate, creamy and subtle.
The only known outlet is the Caviar House & Prunier in London England’s Piccadilly that sells a kilo of the expensive Almas caviar in a 24-karat gold tin for £16,000. The Caviar House also sells a £800 tin for those on a smaller budget!
Beluga. Probably the most recognisable name in Caviar which has led to its scarcity and after the Almas is the most expensive. Beluga eggs are the largest and are light grey to nearly black with a fine skin that melts in the mouth. The flavor is delicately fishy.
Oscietre sturgeon are much smaller than its coveted relative, the Beluga sturgeon. As caviar, it is of firmer texture than the more delicate Beluga caviar. It has a very rich flavor. Ossetra caviar ranges from warm brown to green-gray in colour, to dark blue to jet black or even yellow. Ossetra caviar is distinctive by its nutty flavour and so is prized as an elite caviar.
Sevruga. This, by look is most likely what people imagine as caviar, the small black eggs are typical of Sevruga, these are the smallest sturgeon whose grey-black eggs are fine grained. They taste distinctively salty. Sevruga is the least expensive al all the above , yet highly prized for the unique flavor,
And the best ways to eat it are,
Most people recommend that you use a horn spoon for the scooping of the eggs and then place said eggs on the fleshy part of the hand between thumb and forefinger, leave it for a few seconds to heat up and then lick it off, popping the eggs on the roof of your mouth. Others would recommend spooning some onto delicate melba toast and eating that way, either way its bound to be the most expensive item you are likely to eat so enjoy it whichever way you want.
