# How to Properly Fill Your Portafilter? Complete Guide 2025 Abstract

This article examines the critical technique of portafilter filling for perfect espresso preparation. Research shows proper dosing can improve extraction efficiency by 25%. Optimal amounts vary by basket size: 7-10g for singles, 16-18g for doubles, and 20-22g for triples, with grounds sitting 3-4mm below the rim after tamping. Overdosing causes bitter flavors, while underdosing produces weak coffee. For consistency, use precise scales, dosing funnels, and distribution tools. Light roasts benefit from higher doses (17-19g), dark roasts from lower (15-17g). Professional baristas typically start with a 1:2 brewing ratio. Mastering these techniques significantly enhances espresso quality and flavor.
