Coffee Brewing Tips

Grind Consistency

Use a burr grinder for consistent particle size. Blade grinders create uneven particles leading to uneven extraction. Match grind size to your brew method.

Water Quality

Use filtered water with balanced minerals (50-100 ppm TDS). Avoid distilled or heavily mineralized water. Good water = better extraction.

Brewing Technique

Pre-wet your filter to remove paper taste. Bloom freshly ground coffee with 2x its weight in water for 30 seconds. Pour in circular motion for even extraction.

Storage & Freshness

Store coffee beans in airtight container away from light, heat, and moisture. Grind just before brewing. Use within 2-4 weeks of roast date.
