The aroma lingered. I had inhaled deeply and the bouquet was smoky but sweet, with a hint of fresh blossom. Yes, it had to be a dark Oolong.
A good year, no doubt, but this was no Hunter Valley cabernet. It was Chinese tea, and I was the only Westerner in a group of around 30 who were being groomed in the fine art of drinking it.
Ironically, the building where we were sniffing and sipping from tiny porcelain cups had been designed for people with far less delicate pursuits.
Flagstaff House's first occupant, way back in 1846, was Major-General D'Aguilar, officer commanding the British land forces in China.
And apart from World War II, when Japan invaded Hong Kong and it became home to one of their admirals, it continued to be used by commanders of British forces right up to 1978.
Chinese tea and military strategy had, however, been far from my mind when I set out on this day's walk. My main interest had been some of the historic buildings which have survived the development onslaught in Wan Chai and Central.
Few would think of going to Central for a weekend stroll, but hidden beneath the cluttered, towering office blocks are some fine examples of Hong Kong's past.
