Yeah Neutral12 (Hi by the way if you're who I think you are

), it does make sense, I think what the concern is is that each created alcohol takes up its own item space in inventory/storage, though in the end really it's either that:
A.) All Alcohol share the same Item ID so there should be no problems,
B.) "Natural Alcohol" (drops off monsters etc.) and "Created Alcohol" (By alchemists/biochemists) have different Item IDs
C.) All Created Alcohol have different Item IDs depending on who makes them (Extremely unlikely I think, but if it is the case that makes things a little annoying)
So it more or less depends on how eAthena handles Item IDs concerning creations (as well as whether or not the SQI creation script takes this into account if it's B or C), something I'm unfortunately not versed in. @_@a
