History Notes
Sapa was made by the Romans. Romans disagreed on how much reduction of volume was needed; some said you had to reduce the grape juice to 1/3 of its original volume, others said reducing it to 1/2 was enough to call it Sapa.
Columella says “sapa” was reduced by one-half: “Some people boil their must down by a quarter, that they have have put in lead vessels, others cook off a third of it, but without a doubt, if you cook of a half of it, a better sapa will be made.” (“Quidam partem quartam eius musti, quod in vasa plumbea coniecerunt, nonnulli tertiam decoquunt; nec dubium quin, ad dimidiam si quis excoxerit, meliorem sapam facturus. De Re Rustica, Chapter 12, 19,1)
They often used Sapa along with verjuice to create a sweet-sour taste.
