Although this oolong is dark, it is not at all roasted. The red-amber cup is rich and sweet (hence the name) with notes of molasses and honey while the aroma tends to be more savory. No astringency or bitterness here!
Because the leaves are tightly rolled, you can get many infusions from this oolong, each somewhat different from the last. Use hotter water and longer steeping times to bring out more complex and spicy flavors or use cooler water and shorter steeping times for a sweeter brew.
