I would like to make some wood water cups (known as Kuskas). A combination of turning and carving. There will be no oil or film finishes used.
What I would like to ask you guys is this: are there any common domestic species that would NOT be suitable for use as drinking cups? Are there any woods that would likely impart an undesirable taste to the water?
Possible offenders that occur to me might include oak, cedar and yew...but I dont know. Those of you who do, please sound off. Thanks.
