  • 44 - Adulterated coffees and high end specialty coffee

    This is a niche topic but one that gets some industry people fired up - adulterated coffees, experimental processes, transparency, honesty and specialty coffee. In this conversation we tried to stick to one question about whether specialty coffee’s reputation is at risk from ‘undeclared’ additives. We didn’t succeed. For many of us in specialty coffee, the issue is too tied up in our values, identity, personal prefences, and the brands of our businesses.The best document to understand the full picture was released by the SCA and is called Green coffee identity.When Paul, Tibor and I were talking a few weeks ago, Tibor decided he had to raise the question of whether adulterated coffees are a risk for high end specialty coffee. What happens when a roaster buys an experimentally processed coffee, that is supposed to have flavours developed through fermentation, but in fact, they come from the addition of an artificial syrup?We discussed this and went down a few tangents.1. Doctored coffees and trust at the high end2. Andrew’s risks-versus-opportunities framing3. Signature drinks and the “identity crisis” question4. Hyper-specialty’s lineageSome useful references:

  • 40 - What happened to balance in coffee with Peter Giuliano

    On the surface, this is a niche topic about a single attribute in the sensory evaluation of coffee. In fact the removal of balance from sensory scoresheets underpins much of the updated conception of how coffee professionals can subjectively and objectively evaluate the sensory experience of coffee.
    If you're a cupper who is alarmed at the assertion that scoring coffee 80+ to make it specialty is subjective, rethinking balance could open a door to a new understanding. If you're a cupper who is upset that there is no longer an objective overall score for coffee, Peter argues that the subjective experience is a higher order experience, hard to quantify, but is still critical for the sensory evaluation of coffee.
    This conversation between Andrew Tolley and Peter Giuliano traces “balance” from its origins as a wine term, which Ted Lingle imported into coffee cupping in the 1980s as part of the *Coffee Cuppers Handbook*. We discuss its quiet removal from the Coffee Value Assessment (CVA) system as a result of feedback from a survey of 1,600 cuppers through to its current, softer echo in World Coffee Championship “taste experience” scoring.
    This podcast episode of the Coffee Knowledge Hub Podcast covers:
    -history of balance as an attribute in coffee
    - with new and diverse tasting experiences — from traditional specialty coffees to trendy, innovative styles — how we can build standards for different environments
    - how we can bring different modalities into the tasting experience to better capture the overall perception of a coffee
    - how we can communicate with customers and serve balanced, consistent coffees for different audiences
    Peter and Andrew close the episode by diving deeper into practical tips for cafes to deliver a balanced, consistent espresso to their customers. So definitely stick around until the end.
    And if you have read this far and just want to know what balance is: It was defined as the interaction of flavour, aftertaste, acidity, and mouthfeel. Where a higher scoring coffee had all the positive impressions that the cupper expected and none of these dominated or detracted from another in a negative way. The cupper would score it 6-10 based on their impression.
