Scott Rao makes Filter3 coffee
Steps to Make Scott Rao's Filter 3 Coffee
Preparation
- Pour 22g of very coarsely ground coffee into the basket.
- Give it a gentle shake to level the grounds.
- Flush the group head (using the Decent “Dimples” shower screen, which has 50 small protrusions to ensure even water distribution).
Brewing Process
- Latch the basket onto the machine.
- Press the button to start the brew—everything else is fully automated.
- The entire process takes ~4 minutes.
Optional Manual Check (At ~100 Seconds)
- Remove the basket to check the slurry level:
- Optimal grind: Slurry is ~50% up the basket.
- Too fine? Slurry is 60% or higher → use a slightly coarser grind next time.
- Too coarse? Slurry is below 40% → use a finer grind next time.
Filter 3 Profile Details
- Pre-wet phase: 3:1 ratio (~66g water for 22g coffee).
- 30-second bloom follows pre-wet.
- Slow-flow stages with gradually declining water temperature (to avoid over-extraction).
Expected Results
- Extraction yield: ~22-23%.
- TDS (Total Dissolved Solids): 1.4-1.5%.
- If too strong, dilute with 30-40g water after brewing.
Why Filter 3 is Great
- Simple & consistent – just press a button.
- Time-saving – ideal for events or roastery use.
- Reliable – produces perfect filter coffee every time.
Filter3 baskets are available at Scott Rao's web store and at Decent Espresso's website.
