Imperial Oscietra Gold comes to us from the sturgeon species Acipenser gueldenstaedtii also known as the diamond sturgeon and is one of the most exclusive types of caviar. Whilst it comes in varying colours, the lighter golden coloured eggs are the most sought after and are harvested from the oldest of sturgeon. The time required to harvest this luxurious caviar is 10-12 years, It's reputation is from the days when the Shah of Iran is said to have reserved all that was produced!
