What it means
The most common basket in modern espresso work, sized for doses roughly in the 14–21 gram range. It tends to produce more even extraction and is easier to work with consistently than many single baskets, which is why it dominates both professional bars and serious home setups.

Where this leads
Each one pushes this into the cup, compares it, or helps you act on it.
How the basket changes things
Headspace
Basket geometry becomes cup behavior through headspace.
Match dose to basket size so the puck sits where the machine expects it to.
The numbers that define the shot
Dose
Basket choice only makes sense once the dose fits it.
Use a scale for every dose when dialing in. Precision here saves time everywhere else.
How you read the result
Yield
Then read the output to see what the basket did.
Think of yield as the result you are aiming for and brewed weight as the way you verify you hit it.
What people mean when they say "extraction"
Espresso Extraction
Translate basket behavior into taste.
Separate extraction from strength in your thinking. One asks how much was dissolved, the other how concentrated the drink feels.
