Quick answer

Choose Dark Roast Profile if you brew dark roasted beans and want bold flavors to shine; choose Classic Light Roast Profile for lighter roasts where subtle notes matter most.

Why water matters for your AeroPress brew

The water you use directly affects extraction. Third Wave Water sticks are mineral concentrates designed to mimic ideal brewing water. The Classic Light Roast Profile and Dark Roast Profile each adjust mineral content to complement specific roast levels.

Roast-specific mineral balance

Light roasts benefit from a mineral profile that enhances acidity and clarity. Dark roasts need a different balance to soften bitterness and bring out chocolatey or smoky notes. Using the wrong profile can mute or distort the coffee's character.

Trade-offs at a glance

  • Classic Light Roast Profile: Best for light and medium-light roasts where you want to highlight fruity or floral notes. Works with 1-gallon, 5-gallon, or 2-liter batches. Matches well with single-origin light roasts brewed with a longer AeroPress steep time.
  • Dark Roast Profile: Optimized for dark roasted beans to emphasize chocolate, caramel, and nutty flavors while reducing bitterness. Available in stick sizes for smaller or larger batches. Ideal for traditional dark roast drinkers who want a smoother cup from their AeroPress.
  • Price and value: Classic Light Roast Profile is USD 21.17 per box (catalog price USD 29.00); Dark Roast Profile is USD 11.88 per box (catalog price USD 18.00). Both offer savings versus list price. If you brew both roast types regularly, consider buying one of each to match your daily bean.
