There's just been another bunch of people killed drinking ethanol tainted homebrew in Indonesia, this time in East Java.
For those concerned, here is a wrap on how the ethanol gets into the drink. Unlike what some media reports are suggesting, the ethanol isn't added to the booze, rather it's a by-product of dodgy distilling.
This remains particularly a problem in Indonesia where excessive alcohol prices (via tax) encourage home distilling, but is also common in some parts of Thailand.
Unfortunately it is near impossible to tell by drinking it - the best way to be tipped off is a ridiculously low price -- yup those 10 baht V&Ts are probably not at all the real thing.
