I would say: yes and no
You can smell
(no joke) if the yew was growing on sour or alkaline ground. Alkaline give you the chance for a hard, fast and tough wood. Most with less physical weight.
The sour one is softer, more flexible and clearly less drawweight with the same bow-dimensions.
The other thing is the gender from the yew...
To have a chance for a outstanding yew you should keep a eye on:
Fakt:- alkaline (smells like sand if you rasp or saw them, not clearly sour)
- female (red berries)
- a ringcount over 25rpi
- more salmon corewood then brownish
- straight
If you do that, then the chance to pick a real good stave will increase enormous.

The rest is hokus-pokus and you have to be a skilled bowyer.
