Garrett Oliver (born July 29, 1962)[1] is an American brewer and beer author from New York City.

Oliver studied filmmaking at Boston University, and as a student organized concerts for bands such as R.E.M., The Ramones, The English Beat, and The Gun Club.

He then traveled in Europe, sampling beers in countries such as Belgium, West Germany, and Czechoslovakia.

[2][3] After returning to the United States in 1983, he began homebrewing, working for HBO and a New York law firm.

He was the first (with Bill Taylor) to be given this title from the British organisation that educates and certifies beer sommeliers.
