Cashel Blue is a semi-soft blue cheese made on a Tipperary farm since 1984 from pasteurised cow milk, a starter, Penicillium roqueforti and vegetarian rennet. The soft curd drains in moulds for a few days, is salted and pierced with needles so air reaches the mould, and ripens for about two to three months before it is wrapped in foil. Made in 7 steps over 58 days – 59 days. The longest step, pierce and ripen, takes at least 56 days (Bord Bia (Irish Food Board)). Lactic starter cultures and Penicillium roqueforti do most of the fermenting.

What makes this one different
Cashel Blue is a small farmhouse blue made from pasteurised cow milk with vegetarian rennet. It is sold from about 8 weeks old, and as it ages its chalky, mild centre turns into a soft, buttery paste with a stronger blue taste.
Size
About 1.4 kg wheels, also sold as 350 g and 175 g sections
Ripening
From 8 weeks for young wheels; 12 to 14 weeks and more for extra mature
Louis and Jane Grubb returned to Beechmount Farm in 1979 and bought a herd of 90 cows. Jane began making cheese in 1980, in an old copper brewer's vat, and the first Cashel Blue was ready in 1984; the makers call it Ireland's first farmhouse blue. Their daughter Sarah and her husband Sergio Furno took over the maturing in 2004, and a new dairy was built in 2011.
