Not usually. There are two types of brewers pitch, dark and blonde. The dark works better in wooden vessels, as its a bit more brittle. I've used the blonde in leather, and even gourd, canteens and such, and never had a problem with an off taste. If you want a real taste treat, try taking a pull from an untreated water gourd after it's sat around for a day or two.
