The dark violet glass hoppers are one of our bestsellers after a short time of being introduced and for sure there are many reasons for this. Dark violet can be paired with many colours in and around your space - furthermore, a black grinder, which is the favourite colour of grinders, is a perfect match. The dark violet works with black and polished metal parts as well. This colour is really colourful without being aggressive or pushy.
But even more, the most important reason to choose the dark violet colour might be that it protects your sensitive products (in this case, the coffee beans) against light and the bad influence of the light. The violet glass blocks a lot of the spectrum of the visible light and lets the violet light pass through. As for this, your beans are protected in a very good way against ageing. The darker the violet, the better the protection. As you should not store the beans in the glass hopper for a long time at all, the normal dark violet is already a very good protection for sunny grinder locations and spaces which are flooded with bright light.
