You can’t buy the real Thai whiskey anymore. I was gutted when I went last year. My favourite was Sang Thip but alas, not available anymore, I believe due to the content of formaldehyde (amphetamine – speed). I found Mekhong too harsh (Sang Thip was also very harsh but just slightly less).
All of it tastes like piss alone but nice with Coke (If you order a half bottle in a Thai bar you would get 2 cans of coke with it).
Sang Thip was highly addictive – 5 of us found out the hard way by drinking it every night for 2 months and all getting withdrawals afterwards. We loved how it made us all stay up all night and talk till the cows came home, then we found out it had speed in it!.
Ive heard about the Hong Thong but not tried it…yet.
