I never read any psakim on wine like that. He’s matir Welch’s grape juice because that davka is produced all by machine.
Also, Polly-O mozzarella (before the OU) had Conservative rabbinical hashgacha, and R’ Abadi allowed that because there was a fully automated process in place; i.e. machines poured microbial rennet into the milk, and human hands never handled the cheese-making process.
