I've just found that Asahi is now brewed here locally. A good, dry, consistent Japanese beer to be sure. Comes in can, small bottle and large bottle which state:
"Brewed and canned/bottled under supervision of Asahi Breweries,LTD, Tokyo, Japan by Pathumthani Brewery co., LTD, 2 Moo 9, Bangkuwat, Pathumthani, Thailand...."
I'll have to revert on price as I don't know it at the moment. It is going down smooth though, more so than the aforementioned Federbrau. Pete
EDIT: You should find it at most 7-11's, along with Beer Lao. I see both of these a lot here in the East, in almost every 7-11 so assume they have a deal to carry them.
