Online venture Sibay Shiok has recently expanded their range and is now selling premium Black Gold durians. These will be sold at $120 for an 800g box. Black Gold durians are similar to Mao Shan Wang ones but with stronger bitter notes. They also have black gold veins, which is what gives the variant its name.
Terence Cao sourced these durians specially from Raub in Pahang "from trees ranging from 15 to 40 years old". He also personally does quality checks when the durians reach Singapore before sending them to a durian trader for packing.
According to asiaone.com, Sibay Shiok will only provide deliveries on Mondays, Wednesdays and Fridays as those are the days the durians arrive in Singapore.
