Frequently Asked Questions About Quamar Espresso Grinders & OEM Replacement Parts
Who is Quamar and what is their heritage in Italian espresso grinder manufacturing?
Founded in 2000 in Altivole (Treviso), Italy by Mirco Martignago and Luca Quagliotto, Quamar was established on decades of specialized Italian manufacturing heritage rooted in the historic commercial grinder craft of Veneto (carrying forward engineering traditions associated with the original Fiorenzato heritage).
Quamar is globally acclaimed for producing commercial and prosumer coffee grinders that emphasize durability, heavy-duty cast aluminum bodywork, high-torque industrial motors, and precision-machined steel burrs designed to deliver consistent particle distribution in demanding commercial cafes and discerning home barista stations.
What are the key models in the Quamar espresso grinder lineup?
Quamar engineers a comprehensive range of grinders tailored for domestic prosumers, boutique specialty cafes, and high-throughput commercial venues:
- Quamar M80 Series (M80 Electronic / On-Demand, M80 Doser, M80 Timer): The iconic flagship workhorse. Features commercial 63mm hardened flat steel burrs, a high-torque 300W motor (1400–1600 RPM), and electronic touchscreen programming for single, double, and triple doses.
- Quamar Q50 Series (Q50 Electronic / Push-Button): A compact prosumer grinder equipped with 54mm flat steel burrs. Engineered for space-conscious home coffee bars, small offices, or as a secondary cafe grinder for single-origins and decaf.
- Quamar Q13 Series (Q13 Flat 75mm/83mm & Q13 Conical 71mm): Industrial-grade "Titan" grinders built for high-volume coffee shops, roasteries, and hospitality venues, delivering rapid output up to 4–6 g/sec with advanced thermal management.
- Quamar Sirio Q:** A high-end commercial electronic grinder engineered with precision transmission mechanics, an intuitive digital interface, and ultra-fine micrometric grind regulation for specialty coffee extraction.
Flat Burrs vs. Conical Burrs: How do they compare across Quamar models?
Quamar offers both burr geometries to suit distinct roasting profiles and extraction preferences:
- Quamar Flat Burrs (54mm, 63mm, 75mm, 83mm): Produce a unimodal particle size distribution with high uniformity and fewer stray fines. This delivers high flavor clarity, crisp sweetness, and distinct origin note separation, making flat burrs (like the M80's 63mm set) the benchmark for medium and light specialty roasts.
- Quamar Titan Conical Burrs (71mm on Q13 Conical): Produce a bimodal particle distribution with intentional micro-fines. The fines provide hydraulic resistance in the portafilter basket, generating a heavy, syrupy body, velvety mouthfeel, and dense crema—ideal for traditional Italian dark roasts, high-volume morning rushes, and rich milk drinks.
How does Quamar Electronic On-Demand dosing technology work?
Quamar’s on-demand electronic models dispense freshly ground coffee directly into the portafilter to prevent ground oxidation:
- Precision Digital Timed Dosing: High-definition capacitive touchscreens or push-button interfaces allow baristas to program single, double, and extra-large triple doses down to 0.05 to 0.1-second increments.
- Continuous Manual Mode: A dedicated manual pulse mode allows top-offs or quick purges between roast changes.
- Integrated Dose Counters: Onboard digital microprocessors track total shot cycles, helping commercial managers monitor bean consumption and forecast burr replacement intervals.
Stepped vs. Stepless Micrometric Adjustment on Quamar Grinders:
Depending on the model, Quamar provides two adjustment approaches:
- Precision Stepped Collar Adjustment (Standard M80/Q50): Uses a heavy-duty notched ring mechanism that locks securely into place, preventing grind drift caused by high-vibration commercial motor operation while allowing repeatable reference points.
- Stepless Micrometric Regulation (Sirio Q & Specialized Series): Eliminates preset notch clicks, allowing infinite, sub-micron adjustments to dial in 9-bar espresso extraction times to the exact second.
What routine maintenance, cleaning, and burr replacement schedules do Quamar grinders require?
Consistent care preserves cutting performance and shot quality:
- Monthly Cleaning Tablets (e.g., Urnex Grindz): Run food-safe grain cleaning tablets through the hopper every 4 to 6 weeks to absorb built-up coffee oils and loosen compacted fines from the burr flutes without disassembling the grinder. Never use water or liquid cleaners on burrs.
- Chute & Declumper Maintenance: Periodically remove the bean hopper and top burr carrier to brush out the grind chamber and clear the anti-static delivery chute.
- Burr Replacement Intervals: Standard Quamar 63mm hardened flat steel burrs maintain peak sharpness for 800 to 1,200 lbs of coffee (equivalent to 5–8+ years in home use or 6–12 months in a busy commercial cafe).
