Kaluga Caviar (Huso dauricus) is one of the most luxurious types of caviar, often referred to as "River Beluga". This caviar is known for its impressively large beads, not too soft; more robust than some smaller-sturgeon caviars, with a clean "pop" or gentle burst between the tongue and the roof of the mouth, releasing a rich and buttery flavour with a slight nutty undertones. The eggs range in colour from a light olive-green to a deep, shimmering brownish-black or dark grey. Attilus Kaluga caviar is Malossol which literally means 'lightly salted', salt content being less than 4%.
