I’ve been buying my olive oil at a specialty olive oil and vinegar shop for a year or so. Every bottle has the harvest date and the chemistry of the oil on it.
When I first heard there was going to be an olive oil shop where a favorite cafe of mine was - I was thinking how in the world are they ever going to make a go of that. But, they seem to be doing great and have a second store now.
H & I go and pick out a few bottles of oil and vinegar at a time. It’s kind of like shopping for wine.
