Hmmm, I am honestly not endeavoring to be a smart azz, and I can assure you that my advice is sincere.
I have heard this similar tune maybe hundreds of times since I have been around TeaChat. Trying to reproduce a past experience with a long gone tea. I too have been there and done that and with disappointments abound.
What experience has taught me it is often simply best to move on and perhaps explore similar origin teas, etc. There is a whole world of teas out there with seemingly infinite selections available.
Last time I read, Lipton used Ceylon (Sri Lankan) and Kenyan as base for its teas ... but if you are going back more than 5 years, Ceylon was likely the base. You might want to try exploring black teas from this origin. Upton Tea Imports likely has a very large selection from which to choose.
However keep in mind that teas from Ceylon can be quite variable as some are high grown, some low grown, etc. I remember they had a selection simply called "OP" that was actually very affordable and good.
Good luck on your TeaJourney and may it never land you in a final destination!
