There’s this store that was recommended - Despana - that I learned about it.
I guess in Spain they make wine vinegar like most countries but they have the Pedro Ximenez sherry grape - the sweetest among sherry grape varieties maybe?
I have the link to the store here https://despanabrandfoods.com/collections/a-olive-oils-vinegar/products/montegrato-pedro-ximenez-sherry-vinegar-16-years
I use it because I feel like I’m using a real actual product at an affordable price.
I just couldn’t pay $100 for a tiny 6 oz bottle of real balsamic.
But I’m no expert on Spain and their products.
