Details: Innovative, elegant and made of the highest-quality melted crystal glass, German manufacturing company, Stolzle, sets the bar high for glassware. Each glass is constructed of lead-free, scratch-resistant crystal that is brilliant, extremely strong and dishwasher safe. This Port Glass has a Bordeaux shaped bowl with a sloping out rim to allow the alcohol fumes to disperse. The rim keeps the imbiber's nose out of the glass to not overwhelm with the strong flavors and smells of an aged port. Durable for every day use.
