Cow milk, raw or pasteurised, is set with rennet and cut about 1.5 hours later, first into four pieces and then into hazelnut-size grains. The curd is shaped between wooden planks, turned 4 or 5 times a day for two days, cut into cubes and salted. In damp cellars the cubes are washed 2 or 3 times a week for the first fortnight, then weekly, and ripen 5–6 weeks for the mild doux or 2 months for the piquant.
The PDO summary names the water used to wash the cheeses and the planks as a source of the cellar ferments.[herve-pdo]

Cow milk, raw or pasteurised, is set with rennet and cut about 1.5 hours later, first into four pieces and then into hazelnut-size grains. The curd is shaped between wooden planks, turned 4 or 5 times a day for two days, cut into cubes and salted. In damp cellars the cubes are washed 2 or 3 times a week for the first fortnight, then weekly, and ripen 5–6 weeks for the mild doux or 2 months for the piquant. Made in 6 steps over 51 days – 2.5 months. The longest step, ripen, takes 35 days – 2 months (Ministère de la Région Wallonne 2081). Lactococcus lactis subsp. cremoris, the main species inside the cheese and common on the rind and Rind smear bacteria, mainly Corynebacterium casei, Psychrobacter spp., Staphylococcus equorum and Vagococcus salmoninarum; Brevibacterium linens only 0.5–1.6 % although inoculated do most of the fermenting.
A Belgian washed-rind cheese made as small cubes and ripened in damp cellars where the washing water and walls supply the smear. It is sold mild (doux) after 5–6 weeks or piquant after 2 months.

Total bacteria reached almost 8 log cfu/g in both raw and pasteurised milk cheeses
Herve may be made from raw or pasteurised milk. A study of 11 raw and pasteurised milk cheeses found their microbiota very close, probably because of the shared method. Its abstract reports no pathogen test. CDC advises pregnant women, newborns, people 65 or older and people with weak immunity to avoid any cheese made from unpasteurised milk, because of Listeria.
The PDO summary dates the cheese to the 15th century on the farms around Herve, where surplus milk was kept into winter by fermenting the fresh curd. When wheat exports were banned under Charles V, more land went to pasture by the mid-16th century and cheese making grew. Variants were sold as remoudous (a recipe recorded in 1512), quatre saisons or bizeux. The Pays de Herve tourism office traces the oldest mention of the cheese to 1228 and records cheese owed in a house sale in 1466 and again in 1508. Before 1930 almost every farm in the area made it; by the 1990s about ten artisan cheesemakers remained, and local dairies made 80 % of the 550 tonnes ripened in 1991.
