Prices for a bottle of any better wine start between 280,000 Rupiah and 600,000 Rupiah, depending on where you are. Prices for wine and champagne in many hotels are outrageous compared with Western countries. In general, all imported alcohol is (too) expensive in Bali.
The good news is that the choice of available wines from Australia, California, Chile, France, Italy, New Zealand, Portugal and South Africa has recently increased. If you think the prices of these imports are too high, you should at least try the HATTEN wines, one rosé wine and two types of white wine made from grapes grown in North Bali and sold in restaurants for 160,000 to 200,000 Rupiah and in hotels for sometimes 450,000 Rupiah or more per bottle. The same company is producing also a rosé sparkling wine named "JEPUN" with a refreshing fruity taste. "JEPUN" is about 50% to 100% more expensive than HATTEN Rosé. HATTEN's newer white sparkling wine named "TANJUNG" is also getting quite popular.
Most foreigners like the local BINTANG beer. Many restaurants and pubs also serve BINTANG "draft". Other locally produced beers are ANKER, CARLSBERG, SAN MIGUEL and the less popular BALI HAI beer. In hotels and supermarkets you can also find well-known brands imported from Australia, Germany, Holland, Japan, and even China (Tsing Tao).
Beer is available in all supermarkets and many smaller shops. Wine is very expensive in supermarkets but nowadays there is a number of specialized wine shops where you can find a good choice of imported wines at more reasonable prices. Have a look at the WINE HOUSE at Jalan Kerobokan opposite KAFE WARISAN, the BALI WINE SHOP, Jalan By-Pass 546 in Sanur, BALI DELI in Jalan Kunti and the BALI LIQUOR STORE, Jalan Kunti No. 18 in Seminyak, and at BEST WINES & SPIRITS, Jalan Tangkuban Peradu No. 15D, Kerobokan. The best source to buy Cuban cigars is CIGARS & CIGARS at Kuta Poleng Mall B-5, Jalan Setiabudhi at Jalan By-Pass in Kuta.
Tuak (about 5% alcohol) is a sweet palm wine made from the juice of the coconut palm flower which is stored for about one month for fermentation. Brem is made from black glutinous rice and coconut milk; the alcohol content is about 7% to 9% after three days fermentation. Most popular with foreigners is Arak: a colorless, sugarless spirit distilled from either Brem or Tuak with 20% to 50% alcohol content. A whole bottle costs about Rupiah 40,000, and it is usually served 'on the rocks' as "Arak Attack" or "Arak Madu" (Arak, lemon or orange juice, and honey). You should try it at least once. There is no hang-over as long as you don't mix your drinks, and many visitors don't order anything else after they have discovered Arak.
But be carefull with arak, there is a lot of illegal, bad quality arak in Bali, sometimes mixed with methanol.
