Product description What it does: A compact stone masher set (stone roller plus solid wood stick) for manually crushing and grinding tea leaves, compressed tea cakes, and coffee beans. The roller preserves the stone's natural textured surface to provide effective grinding while the coated surface reduces slippage for safer, easier operation. Key benefits Efficient crushing: The textured stone surface grips and breaks down leaves and beans quickly, reducing effort and speeding prep. Better flavor extraction: Grinding with stone helps release and retain natural aromas, producing a fuller, more balanced brew for tea and coffee. Durable, simple design: Solid stone construction and a hardwood stick create a long‑lasting tool that performs reliably without complex parts. Easy maintenance: No soaking or scrubbing required—wipe with a dry cloth or brush after use to preserve the roller's finish and minimize staining. Features and attributes Material: Durable natural stone roller; solid wood pestle for controlled, comfortable grinding. Function: Manual roller action designed to crush and grind without electricity; textured grinding surface minimizes slippage. Compatibility: Works with loose tea leaves, compact tea cakes (e.g., puerh), and coffee beans suited for hand grinding into coarse or fine particles. Performance: Consistent, low‑noise operation that enhances aroma release while keeping particle size manageable for brewing or further milling. Typical use scenarios 1. Making matchastyle powder from roasted or dried tea leaves by rolling and crushing to a fine consistency before final milling. 2. Breaking apart compressed tea cakes for measured brewing—easier, cleaner separation without tearing delicate leaves. 3. Pre‑grinding coffee beans to coarser sizes for French press or cold brew preparation, preserving aroma before final adjustment. Care and handling After use, remove residue with a dry cloth or soft brush. Do not rinse the stone roller with water; keeping it dry helps retain its finish and appearance. Store in a dry place to maintain the wood and stone condition. This stone masher set offers a simple, reliable way to prepare tea and coffee by hand: durable materials, non‑slip grinding performance, and easy upkeep for everyday use.
