Reserve means nothing, especially in 2020. Maybe a decade ago it stood for something. The majority of things with this brand and DNA has been watered down so thin there is no identity between different levels and base models.
They have more labels to cover the rainbow spectrum of colors. Black label, blue label, etc.
They have also incorporated just about every line into the "SeaBase" badge that was said to be even more limited (as in boutique) than the "Reserve" and sold only in their brick and mortar stores.
