Q50E is the compact on-demand grinder in Quamar's professional line, built around 54 mm flat burrs the manufacturer describes as having a "food friendly" processing. Grind adjustment is step-by-step, with a stated 0.01 mm increment per degree, and doses are set automatically or manually, single or double, through a display with mechanical buttons available in seven languages.
The manufacturer explicitly states the covered uses: espresso, moka, filter and V60, a wider coverage than is typically declared for this grinder category. Power supply comes in two versions, 110-120 V at 350 W or 220-240 V at 330 W, both on 50/60 Hz mains, with the motor running at 1400 rpm at 50 Hz and 1600 rpm at 60 Hz. The standard hopper holds 1200 g, with optional 150, 250, 500 and 1500 g variants.
Stated net weight is 7 kg, with dimensions of 175x260x520 mm. Quamar does not specify the burr material beyond the food-safe processing claim, nor the retention in grams or the number of adjustment steps for this model.

Chosen from the brew methods the manufacturer declares it covers, not from the category.
Seven grams, twenty-five seconds, twenty-five millilitres: Italian espresso has a written specification, and this is it.
The same dose as an espresso, less water in the cup. No institutional source fixes its volume — so here you will only find what is documented.
25 ml of espresso and 100 ml of steamed milk, in a 150–160 ml cup. The cappuccino has a specification too.
An espresso and a stain of milk. How much milk, exactly? No source declares it — and we do not invent it.
An espresso lengthened with hot water. The amount of water is set by no standard: it changes from country to country and from bar to bar.
The moka is not dosed in grams: it is dosed by volume. Water up to the valve, funnel filled level, never tamped.
