These archaeologists found a buried storeroom that once contained 2000 liters of ancient flavored wine, but what I'd like to know is, how exactly did they determine that the additives were "psychotropic"? The wine had long since "leaked out", but perhaps there happened to be rolling papers available to test the residue?

Vintage WINE laid down in SIXTEEN HUNDRED BC was 'psychotropic'
Possibly accounting for concurrent technicolour dreamcoat fad

The people of ancient Canaan were far more bibulous than anyone has previously suspected. Boffins have dug up 3,700-year-old wine jugs from an ancient cellar in a large Canaanite city called Tel Kabri, which is not far from the vineyards of modern Israel.

The wine was flavoured with honey, mint, cinnamon bark, juniper berries and even mysterious "psychotropic resins", which might explain why people in the biblical era spent so much time spouting prophesies and wearing technicolor dreamcoats.

The wine cellar is the oldest ever found in the near east and contained 40 jars of potent, sweet wine. Some fifty litres were stored in the basement, which was found beneath an ancient palace.

Sadly, the biblical booze leaked out a long time ago and all that's left were traces of its ingredient and tell tale signs of tartaric and syringic acid, which are both key constituents of wine. The recipe is similar to "medicinal" wines enjoyed in Europe two millennia ago, although that familar old excuse for drinking is probably as old as civilisation itself....
