I don't do anything special with my yeast either. I usually pour and gosame as Tim. My concernwas prompted because I didn't want to bury the yeast in four packets of saw dust in case that prevented themfrom gettingoxygen. Theoak packs for the Shirazare chips though, not saw dust,and if I had realized that I wouldn't have evenworried about it.
Anyway... I poured the oak in and gently stirred and things look fine. Thanks again everyone for your replies. I have to say it again... my wine family here kicks arse! As Cosmo would say, "giddyup!"
