Forms
moût m (plural moûts)[1] Old and Middle French moust; the spelling moût dates from the 17th century.[2][3][4]
Etymology
It is inherited from Old French moust, inherited from Latin mustum (“unfermented grape juice, new wine”).[5][6][1][7] The Latin noun is the neuter of the adjective mustus (“new”) used as a noun;[8][2] Rey calls it a rustic word with no clear origin.[8][2] Wiktionary links it to a root Proto-Indo-European *mus- (“damp”).[1] The circumflex marks the ⟨s⟩ lost from the Old French spelling.[2]
Cognate with Occitan most, Catalan most, Spanish mosto and Italian mosto.[4]
Earliest recorded meaning
The Grand Robert and the GLLF date moust to about 1112, in the Voyage de saint Brendan;[3][2] the TLFi's first record is in Aldebrandin of Siena's Régime du corps (about 1256), for grape juice meant for wine that has not yet fermented.[5] Littré quotes from Aldebrandin: Quant roisin sont cuit u vin novel, u quant il sont demouré en moust (“when grapes are cooked in new wine, or when they have remained as must”).[4]
Semantic evolution
The word kept the Latin sense of fresh, unfermented grape juice.[8] In 1611 Cotgrave extended it, by analogy, to the juice of other fruit and plants used to make alcoholic drinks, such as apples, pears, beet or barley;[5][8] brewers' moût, the sweet liquid got by steeping crushed malt in boiling water, is recorded by Larousse in 1903.[2]
In the 13th century it gave moutarde (1223, moustarde), a condiment first made with grape must; the English word mustard comes from it.[8][6] Littré records the saying cela n’a ni goût ni moût of a dish without seasoning and, figuratively, of a dull story or book.[4]
