Humphrey Errington diversified into cheese-making in the early 1980s, with the now-famous Lanark Blue being launched in 1985. Ewe's milk Lanark and cow's milk Dunsyre Blue have become two of Scotland's best known and most highly respected cheeses, and, like all Errington cheeses, are always made with unpasteurised milk. The milk is produced on the farm which has 450–500 dairy sheep and these are predominantly Lacaune with some Friesian crossed. Humphrey's daughter Selina now runs the cheese-making business, and introduced Corra Linn – a hard sheep's cheese matured for 6–10 months – to a stable that also includes Lanark White and Maisie's Kebbuck, developed and named for Humphrey's mother-in-law, who dislikes blue cheese.
