Although not Irish in origin, Mead, also called honey wine, was a very popular drink in many countries throughout history. Made by fermenting honey and water, and later introducing a grain mash, Mead is more like a Honey/Ale mixture.
Mead has made a comeback in the last few years as an alternative drink somewhere between beers and liquors. Combining the sweetness of honey with the bite of alcohol, meads are popular after-dinner drinks. The variety can be bewildering, some meads are similar to wine or beer, others are medium-strength liquors.
