It originated in the United Kingdom to be exported to India, which was under the control of the British East India Company until 1858. Its higher hop content acted as a natural preservative, preventing it from spoiling during the long shipping voyage. IPA has since regained significant popularity, and is associated with craft beer. History. The pale ales of the early 18th century were lightly hopped and quite different from today's pale ales.
