Followed some advice, lower temperature (just under rolling), more tea (three spoons for 2 cups), shorter brew time (3 minutes) and it has worked wonders on my Lapsong. The dark amber of the two was in full swing by 3 minutes, almost looking like rooibos. It was smokey but no bitterness in the end. In fact the end tasted like water, perhaps too thin?
The second steeping (3 minutes), this time no sugar, tasted of green tea, wondrous, and the smoke has settled to a low ember, not burning at all- excellent to the palate.
