What blessing does one recite on wine lees (dregs), and what is the water-dilution ratio that determines the blessing?

Synopsis

Undiluted wine lees get Hagafen. When 3 parts water are added and 4 parts result, it is considered mixed wine (Hagafen). If less than 4 parts result, it is mere acid (Shehakol). Modern wines are weaker so this ratio does not apply; one measures by local mixing custom. The Rema adds wine must not be less than 1 part in 6 of water.
