True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.

Cheese from Portugal, Beira Baixa
Raw ewe or goat milk, in any mix, is set with animal rennet at 27–36 °C, cut with a lira, pressed in hoops and salted heavily, often in stages. The cheeses are then stacked under salt in a 'castelo' for 2–3 weeks and laid on edge on beds of rye straw, cleaned of their sticky surface for at least 120 days. The result is a rindless, hard, greyish cheese that is very salty and sharp. Made in 6 steps over 4.4 months – 4.6 months. The longest step, cure on rye straw, takes at least 3.9 months (DGADR). Lactobacillus plantarum and L. paracasei and Enterococcus faecium, E. faecalis and E. durans do most of the fermenting.

Picante is salted far more heavily than the other Beira Baixa types, cured in a salt-covered stack and then on rye straw, and must age at least 120 days. It has no rind and may be made from goat milk alone.
Made from raw milk and cured at least 120 days. A survey of 98 raw-milk cheeses from Beira Baixa makers found Listeria monocytogenes in 4.1 % of them and linked contamination to lapses in hygiene. Store at 0–5 °C.
Hazards the sources name: Listeria monocytogenes (4.1 % of 98 retail raw-milk cheeses from Beira Baixa, all types).
Every number is labelled with how it is known. How this atlas is made
The salt-stack and straw-bed curing was a farm method in Beira Baixa and was written into the specification by the 2020 amendment. The three Beira Baixa types were registered together as a PDO in 1996.
