from Orkney to the Isle of Arran in the south and includes the northern isles and much of Inner and Outer Hebrides, Argyll, Stirlingshire, Arran, as well as sections of Perthshire and Aberdeenshire. (Other sources treat The Islands, except Islay, as a separate whisky producing region.) This massive area has over 30 distilleries, or 47 when the Islands sub-region is included in the count. According to one source, the top five are The Macallan, Glenfiddich, Aberlour, Glenfarclas and Balvenie. While Speyside is geographically within the Highlands, that region is specified as distinct in terms of whisky productions. Speyside single malt whiskies are produced by about 50 distilleries. According to Visit Scotland, Highlands whisky is "fruity, sweet, spicy, malty". Another review states that Northern Highlands single malt is "sweet and full-bodied", the Eastern Highlands and Southern Highlands whiskies tend to be "lighter in texture" while the distilleries in the Western Highlands produce single malts with a "much peatier influence". Religion The Scottish Reformation achieved partial success in the Highlands. Roman Catholicism remained strong in some areas, owing to remote locations and the efforts of Franciscan missionaries from Ireland, who regularly came to celebrate Mass. There remain significant Catholic strongholds within the Highlands and Islands such as Moidart and Morar on the mainland and South Uist and Barra in the southern Outer Hebrides. The remoteness of the region and the lack of a Gaelic-speaking clergy undermined the missionary efforts of the established church. The later 18th century saw somewhat greater success, owing to the efforts of the SSPCK missionaries and to the disruption of traditional society after the Battle of Culloden in 1746. In the 19th century, the evangelical Free Churches, which were more accepting of Gaelic language and culture, grew rapidly, appealing much more strongly than did the established church. For the most part, however, the Highlands are considered predominantly Protestant, belonging to the Church of Scotland. In contrast to the Catholic southern islands, the northern Outer Hebrides islands (Lewis, Harris and North Uist) have an exceptionally high proportion of their population belonging to the Protestant Free Church of Scotland or the Free Presbyterian Church of Scotland. The Outer Hebrides have been described as the last bastion of Calvinism in Britain and the Sabbath remains widely observed. Inverness and the surrounding area has a majority Protestant population, with most locals belonging to either The Kirk or the Free Church of Scotland.
