My pipes are all barely warm when I smoke them.
Keep them on the warm side, the cooler the better.
So because you but are experiencing Bite, I would go to the extreme, and dry your tabac crispy.
Typically the touch feel test for tabac moisture is to take a small clump and pinch between your thumb and index, and it barely sticks together, it still has a very slight moisture feel.
But for now, you don’t want to feel any moisture.
There are also those that like to always dry their tabac crispy, it’s all really a personal preference.
But what you both should go for is complete dryness, and see what you come up with as far as bite is then concerned.
So it’s all going to depend on your ambient temps, pay attention to how long it takes to get crispy, then if that works, dry less each time, till you find the spot where you notice bite.
This will be determined by the time drying, and pinching the tabac for a moisture test, and in time with all your blends, you’ll know how long to dry and what moisture level works.
It’s been my understanding that Virginias are the worst for bite, especially Red Virginia.
