Be carefull with ilegal alcoholic drink !
Arak bali is one of the famous original balinese alcoholic drink. Some of them are legal. In my understanding, legal means they are checked by the official. They are safe to be consumed. Normally they are sold in bottle.
However, I think more of them (arak) are illegal. In the market, the illegal one is much much cheaper and often you get a really strong one. You can get drunk by let say Rp 20.000? But sometimes you can also get a really nasty one which taste like shit, makes you throw up, headache. No one really knows the exact alcohol proportion even the producer. Normally they are sold in a plastic like a small transparent plastic bag.
Just recently, about 2 weeks ago, about 15 people were dead. They consumed the arak while having a birthday party. After about 1 week ago, more people were dead. damn !! The cause of dead was methanol poisoning. I used to like getting this illegal arak when I was in highschool. A lot of people still do, especially in rural area. They were just unlucky.
So so so, to be safe, please get a legal drink. Scottish whisky is still the best for me. The price of course tell. If you want to try arak, get one in a supermarket or minimarket.
Cheers, have a happy holiday.
