Beer in Antigua Guatemala is available and is cheap if you want to compare prices from around the world. If you order a bottled drink, you will normally get a tissue to clean the bottle. Coca-Cola and Pepsi-type products are available, plus many from local soft drink manufacturers. The reason for the tissue is well bottle caps appear to leave brown ring on the bottles. I guess not the best way to taste the true flavor of the beer.
Antigua has a wide variety of Bars and Restaurants that all sell beer. The prices range from 15Q to 25Q depending on the bar. Beer is also available at grocery stores or Tiendas in Guatemala. Hours of operation are in most cases till 10:00 at night.
Don’t be surprised if you get salt and lemon with your beer. It’s a custom to put some salt on the toes of the bottle, and screw out the lemon in the beer. Sometimes it is mixed with V8 vegetable juice, and the concoction is called michelada.
