Key ideas in The Coffee Connoisseur's Path
- Acids dissolve almost instantly in water
- Thin coffee is a sign of underextraction
- Sugars take more time to break down and dissolve
- Bitter plant matter only dissolves at the very end
- The water didn't have enough time to pull out the sugars
- The chronological order of flavor extraction
- Good acidity adds a refreshing fruit-like quality
- Sourness is a sign the brew stopped before the sugars balanced it
- Over-extraction pulls out heavy, bitter plant fibers
- Distinguishing fruity acidity from sourness
- The water has begun breaking down the actual structure of the bean
- The cause of medicinal or woody flavors
- Saltiness is a chemical byproduct of very low extraction
- The 'sweet spot' happens when sugars mask the initial acids
- A balanced cup has a long, pleasant aftertaste
- The acidity is present but doesn't make you wince
