Just as I thought, some expensive oils and vinegars are lousy and some inexpensive versions are great.
These two were the "hands down" favorites of the panel. Chacewater Olive Oil (500ml) from California has a rich, olive taste with a smooth texture. Melina's Balsamic Vinegar (250ml) from Modena; smooth with a balanced tartness. I pour this "solo" on my salad. This olive oil and vinegar gift set is delivered in an Artisan Gift box.
