The sweet spot between basic espresso and pressure profiling.
Flow control sits in that perfect middle ground between standard espresso machines and full pressure profiling systems. It gives you the ability to manually restrict water flow during extraction, opening up new possibilities for shot rescue and flavor enhancement.
But adding flow control too early can be confusing, while waiting too long means missing out on significant quality improvements. This guide helps you identify the perfect timing based on your actual skills and coffee goals.
You've eliminated most channeling through technique but still hit occasional difficult shots
You regularly work with different roasts and notice they behave very differently
You can watch an extraction and know exactly when to adjust or stop
Your shots are good but you've hit a wall in improving them further
Save shots that would otherwise channel or run too fast by restricting flow
Slower flow can bring out more sweetness in medium and dark roasts
Get more flavor from underdeveloped beans by controlling flow rate
Achieve consistent results across different bean batches and roast levels
Slightly restrict flow after pre-infusion to enhance sweetness. Perfect for medium roasts that taste sharp.
Quickly restrict flow when you see channeling starting. Can save shots that would otherwise be wasted.
Maintain restricted flow for 25-30 seconds to extract more from underdeveloped beans.
