Pliny names millet as the main material for leaven. Kneaded with fresh grape must at the vintage, it keeps for a whole year by his account. This entry is a text-only reconstruction; Pliny gives no amounts, and no modern test of the method was found.

Unlike the barley-cake leaven, which can be made in any season, the millet and bran leavens depend on fresh must, so they are made only at the vintage.
Bran-and-must cakesFine wheat bran steeped in white must and dried as small cakes (separate entry).
Safety
Moulds can grow on cereals and dried foods kept in storage, often in warm, damp conditions, and some of them make mycotoxins, which are toxic compounds listed by the WHO as a food-safety hazard. Pliny gives no warning for this leaven, and this entry is history, not a tested method [who2023].
