This site is horribly out of date, but there is a list of possible bottle harvesting yeasts here
It says that you can harvest from Schofferhofer hefeweizen, but its not sure if it is the primary yeast strain or not. Mentions that it is
estery and phenolic, but the mention of diacetyl could mean its a lager bottle-conditioning strain. I guess you won't know until you give it a shot!
