I have not been able to find these locations that are mentioned in the Mishna. I came across this quotequote from Asaph Goor:
The Mishna also (Menahot, 8, 6) points to the regions where the best wine-making grapes were grown: ‘Kerutim and Hatoulim were alpha (first class) for wine (both are points in Judaea); second to them are Beit-Rima and Beit-Lavan in the mountains of Samaria and Kfar Signa in the valley’ (in Lower Galilee).
Where can these regions be found on a map?
I have googled the names. I am also considering asking it at Judaism.SE
