Not being Muslim, the Balinese have nothing against a drink and alcohol is widely available.
Indonesia's most popular beer Bintang is ubiquitous, but local brand Bali Hai is nearly as popular. Bintang is a fairly highly regarded classic light Asian beer, but Bal Hai is a rather bland lager. Also available is the Bali-brewed microbrew Storm, available in several different flavors. Beer is, however, relatively expensive, though still cheap by Western standards: at Rp. 10,000 and up, a small bottle costs at least the same as a full meal in a “local” eatery. In tourist centres, happy hours are widely available before and after sunset, with regular bottles of beer going for Rp. 7,000-15,000 and the giant sizes for around Rp. 12,000 to 30,000.
Bali produces its own wines, with Hatten being the most popular brand, available in white, red, rose (most popular) and sparkling varieties. Quality can be inconsistent, but the red is usually OK and cheaper than imported wines, which can easily top Rp. 100,000 per bottle. Wine aficionados are better off bringing their own bottle in from Singapore or other countries from which they fly into Indonesia. Imported wines are readily available in Bali, but are very expensive relative to everything else. Nicer restaurants will let you bring your own bottle; some will charge a (very modest) corkage fee. Smaller establishments likely won't mind, but neither will they have a corkscrew!
Bali's traditional drinks are arak, a clear distilled spirit that packs a 40° punch, and brem, a fermented rice wine sold in gift shops in attractive clay bottles that are much nicer than the taste of the stuff inside.
Tap water on Bali is not drinkable, but bottled water is universally available and extremely inexpensive (Rp. 3000 or so per 1.5L bottle) and restaurants usually use purified water for cooking. "Filtered" water shops are also common, providing on-site treatment of the mains water to a potable standard. These shops are much cheaper than retail outlets, selling water for about Rp 5000 per 11-liter reusable container, and avoid the waste created by plastic bottles.
Very cheap (Rp. 10,000) are fresh juices or their mixes (it can be watermelon, melon, papaya, orange, lime, banana or any other possible juice). In Bali, avocado (alpukat) is used as a dessert fruit. Blended with sugar and ice — and sometimes chocolate — this is a beverage you can rarely get in any other locales!
If you do not consume alcohol, Bali's fresh juices and creative combinations of fruits will please you to no end. Almost all restaurant menus have a section devoted to various non alcoholic fruit based beverages.
