C. F. Keil and Franz Delitzsch on 1 Chronicles 27:27

1Ch 27:27

Special officers were set over the vineyards and the stores of wine. The שׁ in שׁבּכּרמים is a contraction of אשׁר: “over that which was in the vineyards of treasures (stores) of wine.” The officer over the vineyards, Shimei, was of Ramah in Benjamin (cf. Jos 18:25); he who was over the stores of wine, Zabdi, is called השּׁפמי, probably not from שׁפם on the northern frontier of Canaan, Num 34:10, the situation of which has not yet been discovered, but from the equally unknown שׁפמוה in the Negeb of Judah, 1Sa 30:28. For since the vineyards, in which the stores of wine were laid up, must certainly have lain in the tribal domain of Judah, so rich in wine (Num 13:23.; Gen 49:11), probably the overseers of it were born in the same district.
