In Sidra Ki Tavo, Book of Deuteronomy 28:39-40. It is mentioned that if the sons of Israel won't obey G-d commands and Mitzvot they will get punishments. כְּרָמִים תִּטַּע, וְעָבָדְתָּ; וְיַיִן לֹא-תִשְׁתֶּה וְלֹא תֶאֱגֹר, כִּי תֹאכְלֶנּוּ הַתֹּלָעַת. מ זֵיתִים יִהְיוּ לְךָ, בְּכָל-גְּבוּלֶךָ; וְשֶׁמֶן לֹא תָסוּךְ, כִּי יִשַּׁל זֵיתֶךָ. The punishment mentioned here is that the olive trees and grapes will be destroyed. This punishment is less severe than the wine will be missed and the olive oil will be spoiled. Since it means that the person didn't invest time and money in harvesting nor producing the grapes and olives. So it is not severe from this perspective. So why G-d chose this approach for punishing so the person won't feel the his work was ruined but only the source for production.
