hi,
Treat it like "toddy." If folks can brew toddy, why not beer. Maybe it's because toddy can also be used as paint stripper, thinner, and you can run some motors on it.
There are guys in my local night market that sell bottles of the stuff. Morning toddy is the quality stuff, by evening the toddy has gone off a bit. But if you've been drinking it all day you won't care.
regards, Scott
