Is this really fermented?

[raweater]

I have a recipe of marinated vegetables in one of my books in the fermented recipes chapter. It's basically several vegetables chopped and marinated in 2/3 apple cider vinegar and 1/3 water with several spices and letting it marinate in the fridge for a week or more.

I just tried some after a week and it's great! It has much more taste than day 1.

But am I really getting good bacteria from this? Isn't fermenting normally in a warm temperature? Or is this a sort of cold but week long fermentation process?

Thanks

I think the recipe is probably fermented but not to a huge degree. The recipe sounds interesting. Would you mind posting the entire recipe? I'd love something like that.
