Grape (anggur) is a fruit, wine (minuman anggur) is an alcoholic drink, and grape juice (jus anggur) is a soft drink. Sometimes, indonesians say "Saya minum anggur" without word of "minuman". "Anggur" here means "wine". If "anggur" means "grape", we would use "to eat". "Saya makan anggur".
yes we would say jus anggur for grape juice.
Difference between these words:
Grape= anggur (which still in fruit state)
Wine= arak (an alcoholic drink)
Grape drink= minuman anggur, which usually we say it as "air anggur"
Grape juice= jus anggur( which is not alcoholic)
Hope this will help you
