That's what this grinder is built for.\u003c\/p\u003e\n\u003cp\u003eCrafted from stainless steel with precision-engineered burr options ranging from ceramic entry-level cores to high-nitrogen ghost tooth geometry, this hand grinder gives you full control over your extraction — whether you're pulling espresso, brewing V60, or steeping a French press.\u003c\/p\u003e\n\u003ch2\u003eWhy does the price vary across variants?\u003c\/h2\u003e\n\u003cp\u003eThree things determine grind quality — and price:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurr material:\u003c\/strong\u003e Ceramic burrs are durable and great for beginners.
