Read this from a book called Sideways, by Rex Pickett:
"It was an inky, almost biblical, 100 percent Syrah with truckloads of ripe fruit..."
What does it mean by saying the wine was "biblical"?
I think it means its extraordinary quality: this Syrah was so good like it was in biblical times, when wine
"was a part of daily
life for the people of the Holy Land in biblical times, a
wine-producing and wine-consuming land".
Biblical would seem a strange way to describe wine.
I agree. And personally, I think a simple "all right" or "damn nasty" would cover most of them.
alternatively, "inky, almost biblical" is talking about the colour, as refers to the plague of darkness in Egypt. Biblical usually refers to a dramatic weather change, or plague of some sort; eg "a plague of locusts of almost Biblical proportions"
so in this case the hint is in the reference to its inky colour. ie very very dark
