Mine is a bit excessive but I would humbly just share the information for curiosity sake.
I bought tea over 2 decades and amassed quite a lot of tea. Most, in fact all the time, buying tea is for personal consumption rather than for investment as I enjoy tea very much. Some tea are bought because of obligation, some are samples but most are bought based on intensive testing and evaluating of the tea. My purchase are mostly, almost 99% from vendors and collectors after tasting them and very seldom online as the place I stay has abundance of tea shops and tea hobbyist. I also travel a lot to many countries to purchase tea. ( Right now, I am travelling for more than 2 weeks to hunt for tea and enjoy tea with many collectors and masters in Malaysia
So, how much tea after all these years. I can't really tell but from estimation, puer (from 1960s to present , mostly sheng) around 150kg, white to red tea (incl Yancha) at least 30kg, and many kilos of Darjeeling all info plus minus 20kg, if I can recall from memory. I think I might have even more....hmmmm.
That is a lot of tea and I drink them and taste them at least 3 times a day on different tea averagely.
Most of the time I buy after tasting them vigorously and many can age well and taste well from long storage. I try many methods of storage over the years but most of my tea esp. puer are in dry and sealed storage. The method is controversial but works for me. The rest of the tea are either in sealed bags or in many of the antique tea pewter canister I have collected over the years.
Over the years, I have learned and can sense what tea can age well than the other but still may be wrong sometimes...that is the fun of it. Even white tea age beautifully after many years.
Well, that is my humble collection and it was a great journey to grow with the tea when they age and also the wonderful memories of discovering and buying them. Some friend visit me after every few years and I will keep the same piece of tea to wait for his/her next visit. The tea will mellow like a good aged friendship. That is the joy of buying and collecting tea.
