[Avodah] Ta'aroves of yayn mevushal

[Daniel Israel]

RRW asked what quantity of yayin mevushal would have to be added to aino 
mevushal to give it the status of mevushal.  The responses thus far 
orbit around the issue of bitul, except for RRW's own suggestion that it 
may relate to the proportion of other liquid added would make it no 
longer a hagafen.

WADR, barring any specific sources on this question (which no one has 
introduced) it would seem more likely to me that we must go back to the 
original takanah, which (at least in part) was related to the 
possibility of using yayin for AZ.  It would seem to me that if we add 
enough mevushal to make the yayin pasul for nesicha, then the takannah 
shouldn't apply.  That may be related to the regular shiur for bitul, 
but I don't see any reason to assume that is the case.

Do we know if the standard used to exempt yayin mevushal from the 
takanah of stam yayin is based on what would make it pasul for use in 
the Bh"M or what would pasul it for (l'havdil) AZ?
