The Science of Grinding — Unlocking Flavor in Every Bean
Why Grind Size Matters
Grind size controls extraction, the process where water absorbs flavors from coffee grounds:
- Too fine: Water passes slowly → over-extracted, bitter taste
- Too coarse: Water passes too quickly → under-extracted, weak flavor
Different brewing methods require different grind sizes:
- Tea-bag style bags (Fresbem Coffee): Medium grind for optimal extraction
- Pour-over or hand brew: Medium-fine grind to highlight aroma
- French press: Coarse grind to avoid sediment
Fresbem Coffee ensures the grind is ideal for portable brewing.
How Grinding Affects Flavor
- Surface Area: Finer grounds increase extraction
- Consistency: Uneven grinds cause over- and under-extraction in the same cup
- Freshness: Grinding just before brewing preserves oils and aroma
With Fresbem Coffee, the pre-ground medium roast is sealed to maintain aroma, body, and sweetness, eliminating the need for grinding.
Tips for Optimal Extraction
- Match brew method: Fresbem medium grind is ideal for tea-bag style brewing
- Use fresh water: Filtered water enhances flavor
- Steep fully: Let the bag sit in hot water 1–2 minutes for maximum extraction
- Adjust strength: Use one or two bags depending on cup size and taste
These steps ensure every cup reaches café-quality standards.
Grinding and Cold Brew
Cold brew requires slower extraction:
- Coarse grind prevents over-extraction
- Steep 12–18 hours in cold water
- Fresbem medium roast tea-bag style bags deliver smooth, naturally sweet cold coffee without grinding
