I am trying to reproduce a recipe found in the Roman "cookbook" Apicius, Conditum paradoxum: it is a spiced wine that calls for honey as an ingredient, but it uses a lot (30 % of the volume of the wine).
This means – adapting the recipe, that originally is for 14 11 liters of wine – that for a bottle of wine I should add 230 ml of honey (340 g if considering a density of 1,45 kg/l).
I was wondering if the honey produced in ancient times could be perhaps "lighter" than the honey we know; this could, at least a little, allow me to reduce the sweetness.
