These are my observations, test this too, and see if you notice the same thing(s), because I’ve always experienced the same results.
It is a fact that Briar is very fire resistant, but Briar will collect moisture and have some level of condensation.
Because of the moisture and condensation, I look at it like drying out is curing the wood.
I call this curing rather than drying, because drying something out, doesn’t always means it is at an ideal state, it is simply dry.
After you smoke a bowl smell the chamber, what does it typically smell like? For me personally every pipe I’ve smoked pretty much smells like ash and dottle.
If you notice the chamber smells like ash and dottle after smoking, let the pipe rest, until the smell of the chamber starts to resemble more of the smell of tobacco. If you let it rest long enough, the smell becomes better, even to a point of taking on a sweeter aroma sometimes.
So do this experiment, smoke the pipe, then smoke it the next day, and see how it tastes. Now rest your pipe until the chamber smells nicer, and then smoke the pipe again to compare tastes.
For me personally without fail, every pipe I have rested until the chamber starts smelling sweeter, has given me a better smoke.
The one thing about this drying/curing process, depending on your ambient temperature/humidity, it will make a difference on how long to rest.
For me personally 2-3 days is where my pipes start smelling the sweetest and taste the best.
