What is the difference between the four (4) water profiles?Updated 14 days ago

Currently, Third Wave Water creates 5 water profiles: Classic Light Roast Profile, Medium Roast Profile, Dark Roast Profile, Espresso Profile,  and Cold Brew Profile. Each profile comes in a variety of stick sizes (1 gallon, 5 gallon, or 2 liter). Here are the details of each profile:

Classic Light Roast Profile:

This water profile is recommended for traditional drip coffee brewers or any manual brewing method (AeroPress, Chemex, V60, etc.) providing brighter, cleaner flavors and higher acidity in light roast coffees. Ingredients:

  • Magnesium Sulfate
  • Calcium Citrate
  • Sodium Chloride

Medium Roast Profile:

This profile is designed to optimize your water for medium roast coffee. It contains more buffer than the Light Roast Profile to help provide a more balanced taste with more sweetness and less acidity. It also works great with any brew method. Ingredients:

  • Magnesium Sulfate
  • Calcium Citrate
  • Potassium Bicarbonate

Dark Roast Profile:

This water profile helps provide smoother flavors while preserving chocolate and nutty characteristics in your dark roasted coffees. Ingredients:

  • Magnesium Sulfate
  • Calcium Citrate
  • Sodium Bicarbonate

Espresso Machine Profile:

This water profile is specially engineered for your espresso machines avoiding the use of water boiler-destroying chlorides. It helps protect your machine's boiler while simultaneously providing fantastic shots of delicious espresso. Ingredients:

  • Magnesium Sulfate
  • Calcium Citrate
  • Potassium Bicarbonate

Cold Brew Profile:

This water profile makes it easier to acquire the tasting notes commonly sought after in cold brew coffees like chocolate and molasses as well as creamier body and reduced bitterness. Reduces acidity up to 3x (300% reduction). Ingredients:

  • Magnesium Sulfate
  • Sodium Bicarbonate
  • Potassium Bicarbonate
