Great Espresso starts with great water. The first thing an operator should do is test their water to find out the hardness. Water hardness is measured in grains per gallon, a grain is (64.8 milligrams) of calcium carbonate dissolved in 1 US gallon of water (3.785412 L). Espresso is 85-96% water and that water is extremely important to drawing out the flavor of those expensive coffee beans.
But what determines the taste of a great tasting espresso? Crema! Crema is the flavorful, aromatic, reddish-brown froth made when air bubbles combine with fine-ground coffee’s soluble oils. The strong presence of crema in an espresso shot indicates a quality, well-ground coffee and a skilled barista (professional coffee maker). Crema, compared to drip coffee, helps give espresso a fuller flavor and longer aftertaste. The key to creating that perfect crema is tailoring the hardness of the water and Pentair/Everpure working directly with Specialty Coffee Operators and Espresso Equipment Manufactures developed working solutions to take care of espresso water regardless of the number of grains of hardness at an operators location.
The ESO7, 9607-25 (ESO stands for Espresso, the 7 just means the size of the filter cartridge) is a three-in-one system providing filtration, scale prevention and buffering/softening of the water. The water retains enough mineral to bring out the espresso flavors. The ESO7 will take care of up to 5,300 grains of hardness or at 8 grains of hardness will generate 511 gallons of espresso before it will need to be changed. Need more capacity than that and more ability to work with the hardness of the water you want for your espresso?
The Claris XXL, 4339-14, unit will give you the same great 3 in 1 filter but also give you the ability to generate 2,910 gallons of espresso, (at 10 grains of hardness) but also has an adjustable DUOBLEND™ bypass valve that allows for a more precise adjustment of carbonate hardness. Either system is quick to install, easy to handle and fast to service. Not sure how hard your water is? Confused about what system would help “perfect” your crema? We can help!

The life of an o-ring varies based on how you take care of it and what it is made of. It is very important to your operation to make sure you have the proper o-ring for your filtration application. If you have any questions on changing out your o-rings or whether you are using the proper o-ring for your system,

More than one billion people around the world, most of them in developing nations, lack access to safe water. The result is that preventable waterborne diseases continue to be a leading cause of illness and death globally. Every day, approximately 25,000 people, mainly children in developing countries, die from preventable waterborne diseases, according to the World Health Organization. Pentair has been in search of a solution that not only brings safe water to communities in need, but also ensures that the solution is sustainable at the community level, taking into consideration the complex economic, cultural and geographical constraints that need to be addressed. The solution also needs to have validating methods and standard practices that can be replicated around the world. To accomplish this, the Pentair Foundation funded a multi-year research program in remote Colón, Honduras. The results of the five year program and the impact on the lives of the people in Colón have been profound. The results demonstrated that sustainable access to safe water and adequate sanitation can be provided cost-effectively, and that the health and welfare of the recipients can be significantly improved. Additionally, to ensure that safe treated water continues to be available beyond Pentair’s initial funding period, a microenterprise business model was established, where the local community owns the water treatment systems and users pay their communities a nominal fee for potable water. The individual user fee is established by the local community to cover the ongoing operation and maintenance of their system. Once installed, the system costs pennies per person per day to operate. Leveraging this success, Pentair is partnering around the world by putting its grants, technology and talent to work for communities in need of clean drinking water. By engaging community partners and equipping them with our extensive product portfolio and technical water distribution systems expertise, we are measurably improving water safety and sanitation worldwide. Understanding that everyone’s efforts add up to more effective answers, Pentair is leading through partnership to find a sustainable solution to the global water crisis. Pentair invites others to join in working toward a world where everyone has access to quality water supply. We are making our findings and models publicly available to other organizations and municipalities interested in replicating these cost-effective methods. By turning industry insights into collaborative proactive plans and on-the-ground tools, we are confident that even the most challenging issues can be solved when we unite around smart ideas.
