Netherlands - Breweries

The Grolsch Brewery is a Dutch brewery founded in 1615 by Willem Neerfeldt in Groenlo, The town of Groenlo was then known as Grolle, hence the name Grolsch. Grolsch uses a distinctively shaped bottle for some of its products, known as de beugel or 'swingtop'. Bottles of this type use a flip top cap, eliminating the need for an opener.
