Speck (Speck Alto Adige PGI and Tiroler Speck PGI)Speck
Speck is a boned pork leg that is dry-salted with spices, cold-smoked at no more than 20 °C and then air-dried for at least 20 weeks until it has lost at least 35 % of its weight. A natural cover of moulds grows on it while it dries. The Italian and Austrian versions are separate EU protected names with slightly different rules.

Amounts from a sourceThe specifications fix the leg weights, temperatures and drying times, but not the amounts of salt and spice.
Pork hind legAt least 10.5 kg before boning; at least 5.2 kg boned and trimmed
The boned leg is called a baffa in Italian; delivered at 0–7 °C at the core[eu-speck-aa-2016]

At a glance
Speck is a boned pork leg that is dry-salted with spices, cold-smoked at no more than 20 °C and then air-dried for at least 20 weeks until it has lost at least 35 % of its weight. A natural cover of moulds grows on it while it dries. The Italian and Austrian versions are separate EU protected names with slightly different rules. Made in 4 steps over 4.6 months – 7.4 months. The longest step, air-dry and age, takes 4.6–7.4 months (European Commission 2016) and runs at 10–16 °C (European Commission 2016). Salt is up to 5 % (European Commission 2016). Surface moulds, chiefly Eurotium rubrum and Penicillium solitum and Other Penicillium species do most of the fermenting.
Speck joins the north's smoking with the south's slow air-drying. Unlike Parma-style hams it is boned and opened out before salting, it is cold-smoked, and its minimum drying time is 20 to 32 weeks, set by the weight of the piece.
Tiroler Speck PGI (Austria)Made in the Austrian state of Tyrol from leg, loin, shoulder, belly or neck. The 1997 application gives smoking at 18–20 °C with beech and ash wood, ageing at 10–15 °C and 60–80 % humidity, and salt at most 5 %. Its 2019 single document adds a spice blend of at least juniper, black pepper and garlic and smoke from at least 50 % beech or ash wood.
Farm-made speckIn the mould study, species diversity was higher in speck from butcheries and farmers than in industrial speck.
Mountain productSpeck Alto Adige made at least 600 m above sea level may add "prodotto di montagna" to the label.
Safety
The specifications cap salt at 5 % and sodium nitrite at 50 mg/kg; Speck Alto Adige also caps lactic bacteria at 1 × 10^8 CFU/g. Some moulds typical of speck (Penicillium verrucosum, P. canescens, P. commune) are known as potentially mycotoxin-forming.
Hazards the sources name: Potentially mycotoxin-forming moulds among the typical flora (Penicillium verrucosum, P. canescens, P. commune).
The Tiroler Speck file cites a price set for a pound of speck in Tyrol on 23 July 1573. Speck dell'Alto Adige was registered as an EU PGI by Commission Regulation (EC) No 1107/96 of 12 June 1996; Regulation (EC) No 1065/97 of 12 June 1997 added its German names, Südtiroler Markenspeck and Südtiroler Speck, and registered Tiroler Speck. The Speck Alto Adige specification was amended by Regulation (EU) 2017/119 of 13 January 2017 and the Tiroler Speck specification by Regulation (EU) 2019/1027 of 21 June 2019.
