What do you call someone who makes sausages?

Salumist is the term that has (slowly) taken hold in the US for the makers of high-end charcuterie and sausages. I cannot find a dictionary that refers to it. But, I'm seeing it more and more in publications.

The term is derived from the Italian "salumi". Which has the same meaning as charcuterie in French and English, though it does include sausages (especially dried) in addition to cured meats.

Mario Batali's father (Armandino) is a noted salumist. He owns a store named Salumi.

Alternatively, and probably more correctly there is the term Salumi Artisan. Personally, I prefer this one because it is not a neologism twisted upon importation from a foreign language.

If you are not taking about a high-end maker, then typically most would call them either a sausage maker or butcher.

In Italy the traditional travelling pig butchers and sausage makers are the norcini - folklore has them as mystical such are their salumi skills.

Since sausage is charcuterie, the person who makes it could be called a charcutia.
