Cheese from England, the Peak District within fifty miles of Dovedale
Dovedale Cheese PDODovedale
Pasteurised whole cow milk is set with Hartington's own starter and blue mould cultures and rennet, then cut, drained and filled into hoops. The cheeses are brined, pierced and ripened at 8–14 °C, usually for three to four weeks, into a soft, creamy blue. Brining a blue cheese is unusual in Britain. Made in 6 steps over 21 days – 28 days. The longest step, pierce and mature, takes 21–28 days (Defra) and runs at 8–14 °C (Defra). Salt is 2–4 % (Defra). Starter lactic bacteria and Blue mould culture do most of the fermenting.
Total time across the recorded steps: 21 days – 28 days

What makes this one different
Dovedale is a soft blue from the Stilton makers' creamery at Hartington, but it is dipped in brine during making, which the specification says no other UK blue does. It is softer and younger than Stilton, sent out at three to four weeks.
Milk
Pasteurised whole cow milk from the Peak District
Paste
Soft blue; moisture 40–60 %, fat 25–35 %, salt 2.0–4.0 %, pH 5.0–6.0 (target ranges at despatch)
Ripening
Normally 3–4 weeks from manufacture
Size
Cylinder 60–80 mm high, about 200 mm across, 2.0–2.75 kg
Made from pasteurised milk. The specification tests each lot at despatch, rejecting cheese with Listeria monocytogenes or Salmonella in 25 g, or more than 100 S. aureus or 500 E. coli per gram. It ships at 5 °C with a 32-day shelf life.
Hazards the sources name: Listeria monocytogenes, Salmonella, Staphylococcus aureus and E. coli, each with a limit in the specification's despatch tests.
Hartington in Derbyshire has made blue cheese since about 1870, when its creamery opened, and began making Stilton in 1886. Dairy Crest, then the creamery's owner, registered Dovedale as a PDO in 1996, citing the three staff who make it and their inherited skills.
