Glass is a non-porous element.  Bottling in glass means that the beverage is protected from bacteria seeping through its walls.  Furthermore, it is sustainable and the most stable packing material that can be ethically recycled.  Our bottles are so solid (made in Spain) and beautiful, that we discovered many of our customers reuse our bottles like we do; great for dried legumes, soups, nuts, herbs, etc. to be kept in your kitchen pantry or in the fridge, even in the freezer. Some people also use them as vases. We heard you saying “WOW!”
