Congratulations for your patience!

Among the numerous traditional way of storing tea, I am refining my oolong in quantity of 100/150 grams in mylar bags, heat sealed but not vacuum sealed (thickness of 5.1 mm) with oxygen absorbers and desiccant bought in factory sealed bags, in such quantities to guarantee me percentages of oxygen less than 1% and percentages of relative humidity less than 0.1%.
I think this is a good method to age for some time (1 to 7/10 years) oolong tea .. but only time will tell me how is going the refinement.
What is the difference between heat sealing and vacuum sealing? I have never used any of these devices myself, so am unfamiliar with the sealing process.
Well, if in both cases there are oxygen absorbers and desiccant that were purchased in factory sealed bags
, the only factor that varies is the amount of nitrogen present naturally in the air (78%), which will increase to 99,X % due to the oxygen absorbers placed inside the bag.
In my opinion, a higher amount of nitrogen is an important factor for a balanced maturation of tea, hence my decision to not put the tea under vacuum condition, but just sealed.
These are merely personal opinions, only time will tell me if I'm right.
