Experimentation is key to mastering espresso and this interactive espresso calculator is simple a tool to help guide you. Understanding how your roast type and extraction time interact allows you to dial in a cup that matches your flavour preferences. If you enjoy bright, crisp notes, a light roast with a shorter extraction might be your go-to. Prefer something fuller and more chocolatey? Opt for a dark roast with a longer pull.

Two key factors influence the flavour of your espresso: roast type and extraction time. Understanding how they interact can help you achieve the perfect cup, whether you’re after brightness or depth.

Roast Type and Flavour

• Light Roast: Bright, fruity, floral flavours with a lighter body.
• Medium Roast: Balanced acidity and sweetness; notes of caramel, nuts, and chocolate.
• Dark Roast: Bold, rich flavours with chocolatey, smoky undertones and a fuller body.

Extraction Time: Short vs. Long

Extraction time ranges from 15-30 seconds, impacting the taste:

• Short Extraction (15-22s): Highlights acidity and brightness; a lighter, sharper flavour.
• Long Extraction (23-30s): Develops deeper flavours, sweetness, and body; may become bitter if over-extracted.

Matching Roast to Extraction

• Light Roast: A short extraction brings acidity; a longer one enhances complexity and sweetness.
• Medium Roast: Shorter times result in a bright taste; longer pulls bring balance and fuller flavours.
• Dark Roast: A quick shot feels sharp and flat; a longer extraction creates rich, bold notes but can turn bitter.

Finding Your Ideal Espresso

Experiment with combinations to find your preferred flavour. For bright, lively notes, try a short pull with a light roast. For rich, bold flavours, opt for a dark roast with a longer extraction.

Understanding roast type and extraction time allows you to tailor your espresso to your taste—resulting in the perfect brew every time. Happy brewing!
