Aura (Aurajuusto)Finland, Äänekoski

Also called Aura, Aura-sinihomejuusto, Midnight Blue.

Aura is a Finnish blue cheese of cow milk, created in the 1930s as a Roquefort-type cheese made from cow milk instead of sheep milk. The cooked curd is pressed, salted by hand and pierced so Penicillium roqueforti can grow through it. It spends about two weeks in a cool, damp cellar and then six weeks in cold storage.

Size
3 kg wheel, cut into wedges or crumbled; sold as 6 kg wheels at first
Output
About two million kilograms a year
  1. Add the blue mould to the milk
  2. Cook the curd

  7. Mature in cold storage42 days
Bayley Hazen BlueUnited States, Vermont, Greensboro

Bayley Hazen Blue is a natural-rind blue cheese made since 2003 at Jasper Hill Farm in Vermont from raw Ayrshire cow's milk. Each wheel is pierced by hand in the cellar so air can reach the Penicillium roqueforti inside, and it ripens for three to four months into a dense, fudge-like blue.

Milk
Raw cow milk from Ayrshire cows
Ripening
3–4 months
Size
About 7 lb (3.2 kg)

  4. Ripen in the cellar3–4 months

Safety: Made from raw milk and ripened 3 to 4 months, by the maker's account. The US FDA says ageing raw-milk cheese for 60 days may not eliminate or adequately reduce E. coli O157:H7 and Salmonella, and Listeria may grow in some cheeses during ageing.

Beenleigh BlueEngland, Devon, Ticklemore Cheese Dairy at Totnes

Beenleigh Blue is a sheep's milk blue cheese from Devon, first made in 1978 by Robin Congdon, one of the first farmers to milk sheep commercially in Britain. It uses methods like those of Roquefort, pasteurised ewe's milk, a vegetarian coagulant and Penicillium roqueforti; the cheeses are pierced, then wrapped at a few weeks old so that no rind forms.

Bleu Bénédictin is a blue-veined cow's milk cheese made by the Benedictine monks of Saint-Benoît-du-Lac in Québec. The abbey pasteurises whole milk from local farms, sets it with cultures and rennet, brines the wheels and ripens its blue cheeses in cold, humid rooms, where Penicillium roqueforti gives a creamy paste and a mushroom flavour.

Bleu de Termignon is a raw cow's milk blue from the high pastures of the Vanoise, made only in summer by a handful of farmers. No starter or blue mould is added; fresh curd is drained, soured in whey, milled and moulded in wooden forms, and blue mould from the chalet and cellars slowly enters from the rind. Its Penicillium roqueforti is a genetically distinct population specific to Termignon cheeses.

BleuchâtelSwitzerland, canton of Neuchâtel

Also called Bleuchâtel, Bleu suisse, Bleu des Montagnes Neuchâteloises.

A soft, creamy Swiss blue cheese made from thermised cow milk at the Fromagerie Les Martel, a creation of its owner Didier Germain. The round wheels, with a white rind edged with blue, ripen about one month.

Cornish BlueEngland, Cornwall

Pasteurised milk from Friesian cows is set with vegetarian rennet and a blue-mould starter. The curd is cut, shaped by hand and salted, and the young cheeses are pierced with steel rods so air reaches the mould. It ripens only about 12–14 weeks and is meant to be eaten young, mild and creamy.

  1. Add rennet and mould culture to the milk
  2. Cut the curd
  3. Shape by hand and salt

A hand-made, semi-soft blue cheese from the sheep milk of a Friesland flock, made by the family behind cow-milk Cashel Blue. In 2024 the first ewe milk of the season reached the vat on 6 March, and about 80 wheels were made a week. It is ready for market at about 12 weeks but is said to be at its best from 6 to 11 months.

Lanark BlueScotland, Lanarkshire

Also called Lanark Blue, Lanark Blue ewes' milk cheese.

Raw milk from the farm's own Lacaune ewes is seeded with Penicillium roqueforti, set with vegetarian rennet and ladled into forms to settle. The cheeses are dipped in brine, ripen a month, then are wrapped in foil and kept two more months in a cool room until blue-green veins run through a crumbly paste.

Milk
Raw ewes' milk from the farm's own Lacaune flock
Ripening
About three months, two of them in foil
  1. Milk the ewes
  2. Add blue mould and rennet

  4. Dip in brine
  5. Ripen, then wrap in foil3 months

Safety: This is a raw-milk blue cheese. The NHS advises pregnant women to eat soft blue-veined cheeses only cooked until steaming hot, because of Listeria. Health Canada also tells people aged 60 or over, children aged 5 or under and people with a weak immune system to avoid all uncooked cheese from unpasteurised milk. A UK minister told the House of Lords in 1996 that Edinburgh and two other district councils had found this cheese above the Listeria threshold. In the court case with one council, a sheriff found for the maker on 28 February 1996. A different cheese from the same maker, Dunsyre Blue, was named by Health Protection Scotland as the source of a 2016 E. coli O157 outbreak that killed a 3-year-old and sickened 25 others. By the end of 2017 the maker had not accepted that finding, and the Crown had decided not to prosecute.

Perl LasWales, West Wales

Perl Las is a soft, creamy blue cheese made by hand at the Caws Cenarth farm dairy in West Wales from pasteurised organic cow milk, vegetarian rennet, cultures and Penicillium roqueforti, with sea salt. A retailer describes a mild blue, creamy first, then salty with gentle blue notes.

Shropshire BlueEngland, Nottinghamshire

Shropshire Blue is a blue cow-milk cheese made like Stilton, with annatto added so the paste turns orange against its blue veins. It is made from pasteurised milk with Penicillium roqueforti in Nottinghamshire, and is pierced to let the blue grow.

Milk
Pasteurised cow milk
Colour
Annatto turns the paste orange; it is otherwise made like a Stilton
Piercing
One retailer's batch is pierced fewer times than usual, which it links to less intense blueing
Maker
Made in Colston Bassett, Nottinghamshire, for one retailer

Made like Blue-veined cheese family (Roquefort as template).

SticheltonCollingthwaite Farm, Welbeck Estate, Nottinghamshire, England

Also called Stichelton.

Stichelton is a Stilton-style blue cheese made from raw cow milk on the farm where the cows are milked. A tiny dose of starter, blue mould and traditional rennet go into the milk at 28–29 °C; the curd is ladled, drained overnight, milled, salted, hooped, rubbed up and pierced so the blue can grow.

Milk
Raw cow milk, used on the farm where it is milked
Starter
Less than 50 ml of starter to 2600 litres of milk, about 0.0008 %
  1. Warm the raw milk, add starter and mould1 h · 28–29 °C
  2. Rennet for a soft set
  3. Cut, settle and ladle2 h
  4. Drain overnight
  5. Mill, salt and hoop
  6. Rub up the coat
  7. Dry and grow a coat14 days · 13 °C
  8. Pierce and mature

Safety: Stichelton is made from raw cow milk. That is why it cannot be called Stilton, whose specification allows only pasteurised milk. The CDC says people at higher risk, including pregnant women, people 65 or older and people with weak immunity, should avoid raw-milk cheese unless it is heated to 165 °F (74 °C) or until steaming hot.
