Defrutum is not a jelly, it’s more like a syrup: grape juice reduced to a half of its volume, to concentrate flavours and as a preservation method. I’m almost sure that it was available for a wide range of people, not just wealthy ones.

I’ve seen it referred to by various terms and I’m not culinarily educated enough to tell the difference between any of the words. Syrup, jelly, must; it’s all Greek to me! I’ll fix it in my explanation though!

It was available to a wide range of people, but it was a frequent visitor primarily to the tables of the wealthy.

Lead itself isn’t sweet; lead acetate is. There’s a bit of acetic acid even in grape juice, and as you boil it in the lead container both things react together.

I’ll correct that too.
