g more and more polluted, and no longer suitable for brewing beer. A place 1.5 kilometers south-west of the city was then used to take fresh water in. However, the quality of that water was not good enough either. From the 17th century a canal (Santvaert) was used to transport water from the dunes to the city. The water was transported in barrels on ships. The location where the water was taken is called theBrouwerskolkje, and the canal to there still exists, and is now called the Brewers' Canal (Brouwersvaart).
Haarlem was a major beer producer in the Netherlands. The majority of the beer it produced was consumed in Noord-Holland. During the Spanish siege there were about 50 brewing companies in the city; while 45 years later in 1620 the city numbered about one hundred breweries.
There was another epidemic of the Black Death in 1657, which took a heavy toll in the 6 months it ravaged the city.
From the end of the 17th century the economic situation in the city turned sour, for a long time. In 1752 there were only seven beer breweries left, and in 1820 no breweries were registered in the city anymore. In the 1990s the Stichting Haarlems Biergenootschap revived some of the old recipes under the new Jopen beer brand, that is marketed as a "Haarlem bier". In 2010 Jopen opened a brewery in a former church in central Haarlem called the Jopenkerk.
Tulip centre
From the 1630s until present day, Haarlem has been a major trading centre for tulips, and it was at the epicenter during tulip mania, when outrageous prices were paid for tulipbulbs. From the time that the Leiden-Haarlem canal Leidsevaart was opened in 1656, it became popular to travel from Rotterdam to Amsterdam by passenger boat rather than by coach. The canals were dug for passenger service only, and were comfortable though slow. The towpath led these passengers through the bulb fields south of Haarlem. Haarlem was an important stopover
