For the part of you with thirty open tabs that never became anything.

Key ideas in Dialing In Your Home Brew
- Under-extraction pulls acids and salts first
- Over-extraction pulls out heavy tannins
- Lack of finish indicates low sugar extraction
- Hollow taste from over-extraction
- Identify under-extraction by its specific sensory profile
- Identify over-extraction by its physical mouthfeel and flavor
- Acids and salts dissolve almost instantly at the start of the brew
- Sugars and oils follow in the middle, providing balance
- Changing two variables at once makes it impossible to tell which one fixed the flavor
- Plant fibers and heavy tannins extract last, adding bitterness
- The flavor progression in a Salami Shot
- Isolating a single change allows you to map a specific cause to a specific taste result
- Applying the Golden Rule of Dialing to isolate variables
- A brew log creates a repeatable map of your grind settings and water temps
- Recording sensory notes alongside brew data prevents repeating past mistakes
- Finer grinds increase surface area to speed up flavor extraction
