Conti Espresso Machine Portafilter Basket 21g – Double Shot Filter Basket

What Is a Portafilter Basket?

The portafilter basket (also called a filter basket or group handle basket) is the stainless steel insert that sits inside your portafilter and holds the ground coffee during extraction. This 21g double shot basket is designed for Conti commercial espresso machines and is a direct replacement for worn or damaged baskets that cause channelling, uneven extraction, or poor espresso quality.

When Should You Replace a Filter Basket?

• Visible holes that are enlarged, worn, or unevenly distributed
• Channelling during extraction — water finding paths of least resistance through the puck
• Inconsistent shot times despite correct grind and dose
• Basket is dented, warped, or no longer sits flush in the portafilter
• Routine replacement every 12–18 months in high-volume café use

Tips for Best Espresso Extraction with a 21g Basket

• Dose 20–21g of freshly ground coffee for a consistent puck depth
• Distribute and tamp evenly at approximately 15–20kg of pressure
• Aim for a 1:2 brew ratio (21g in : 42g out) in 25–30 seconds
• Rinse the basket after each service to prevent coffee oil buildup
