Perfect Crema!

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 Best Espresso in Town!

Every single morning before arriving to work, Amy stops by her local Starbucks and orders her usual venti latte. They know her there by name and are happy to send her on her way with her triple espresso shot drink. Amy said that her morning espresso kick starts her day and without it, well, you would probably find her half asleep at her desk, struggling to focus on her work.

Espresso can be a vital part of someone’s day, like Amy. Did you know that over 55% of the US drink espresso? That percentage is equivalent to 150 million people! That’s A LOT of espresso! 

Did you also know that Espresso is 90% water! It is a key essential ingredient in espresso preparation. So having a water filtration system becomes a must, especially in areas with hard water. Not having filtered water will affect the taste of your espresso as well as the lifespan of your equipment.  So what is the best water filtration system for your espresso machine?   Well, here’s a couple options to consider: The Claris System 5-Stage Filtration Process

  • Pre-filtration
  • Carbonate hardness adjustment
  • Fine filtration
  • Highly efficient carbon block removes harmful contaminant and unpleasant odors and tastes
  • Solid membrane filter removes particles down to 5 micron for highest equipment protection
  • Operates in vertical or horizontal position

 

3 -Stage Blending: Softens, Buffers, and Filters Water
  • Utilizes ion exchange resin with buffering capabilities and high capacity coconut carbon filtration
  • A small amount of carbon filtered water bypasses softening resin to allow proper initial hardness. 
  • Buffering prevents water from becoming too acidic. 
  • It also reduces hardness in water that can cause minerals to build-up in espresso equipment. 
  • It also reduces chlorine, off tastes and odors. Cartridge replacement is simple, quick and clean.
