What is the ruling on fruit juice that contains a small percentage of alcohol due to natural fermentation, and does its ruling differ from non-alcoholic beer from which the alcohol has been removed, despite its containing a small percentage?

If a large quantity of a juice is intoxicating, then consuming any amount of it is forbidden, for "that of which a large quantity intoxicates, a small quantity of it is unlawful." The criterion for prohibition is intoxication. Thus, any beverage containing a percentage of alcohol that intoxicates is not permissible to consume unless the intoxicating substance naturally disappears. However, if it is removed by human action, the majority of scholars do not permit its consumption.
