The DF64 grinder has become a go-to choice for home baristas thanks to its single-dose workflow and impressive value. One of the biggest upgrades owners consider is swapping in premium burrs. Two of the most popular options are the Red Titanium burrs and the DLC (Diamond-Like Carbon) burrs. To settle the debate, we contacted DF64 Coffee directly—and the verdict is clear: Red Titanium outperforms DLC in the areas that matter most.
Retention
For single-dosing, retention is critical. Red Titanium burrs offer near-zero retention, ensuring every dose is fresh and consistent. DLC burrs, while good, tend to leave behind more fines, which can impact workflow and cup quality.
Grind Quality
If flavour clarity is your priority, Red Titanium is the winner. These burrs highlight crisp, bright notes and bring out the complexity in light and medium roasts. DLC burrs emphasize body and smoothness, making them more suited for darker roasts but less revealing overall.
Heat Control
Grinding generates friction and heat, which can dull flavors. Red Titanium burrs run cooler, preserving delicate compounds and ensuring consistency in long sessions. DLC performs well but generally shows more heat buildup.
Durability
Both coatings are far tougher than stainless steel, offering years of reliable use. DLC is diamond-hard, but Red Titanium balances toughness with low retention and superior flavor clarity, giving it the edge as an all-rounder.
Here's a table summarizing all this information:
| Feature | Red Titanium Burrs | DLC Burrs |
|---|---|---|
| Retention | Near-zero retention, cleaner workflow | Leaves more residual fines |
| Grind Quality | High clarity, crisp notes, emphasizes complexity in light/medium roasts | Smoother body, best for darker roasts |
| Heat Control | Runs cooler under heavy use, preserves delicate flavors | Good friction reduction but warmer in long sessions |
| Durability | Long-lasting, corrosion-resistant, maintains sharpness for years | Extremely hard coating, highly durable |
| Best For | Light & medium roasts, clarity lovers, precision brewing | Medium & dark roasts, body-focused cups |
Final Thoughts
While both burr types enhance the DF64 grinder, Red Titanium burrs stand out as the best upgrade. With near-zero retention, cooler grinding, and a flavor profile that emphasizes clarity and complexity, they’re ideal for anyone looking to unlock the full potential of their beans. DLC burrs are durable and smooth, but if you want top-tier performance, Red Titanium is the clear choice. Shop the DF64 Gen 2 here
