Can you age loose leaf raw?

I normally get cakes, but I really liked this raw loose leaf tea from a tea shop next state over. He doesn't have the exact age of it, it was advertised as "aged 5 years" and normally it's very smooth and a bit smokey and I can usually brew it grandpa style. However, this newest batch tastes much younger and astringent. I'm wondering if I can throw a bovedo pack in the bag and let it sit for a while like I do with cakes? I have 69% two way packs. I unfortunately got 450 grams of it bulk before I knew of the batch or supplier difference because the shop is about 4 hours away and it used to be my favorite tea :(
