What is the best burr size?
Burr Size and Motor Power Larger burrs (64mm–83mm) provide faster grinding and better particle uniformity. Smaller burrs (50mm–55mm) are quieter and more compact, but less efficient for back-to-back shots. As mentioned above, many coffee connoisseurs enjoy the more separated flavour profile of a flat burr espresso shot. However, flat burrs are typically less forgiving than conical burrs and require more accuracy when dialling in your grind size.The consensus among coffee connoisseurs is that a fine grind creates the best espresso.
Which grind size is best?
Quick Answer: Use Medium-Fine Grind For best results, use a medium-fine grind – finer than drip coffee but coarser than espresso. Shake to level the coffee bed and pour water slowly to prevent excessive drip-through. The grind and the contact time with the water therefore influence each other. If the grind is too fine, the coffee quickly becomes bitter and strong. If the grind is too coarse, the coffee tastes rather sour and watery.Yes, the grind size of coffee can affect its taste. If the grind is too fine, the coffee can taste bitter; if the grind is too coarse, the coffee can taste weak and sour. The best grind size for coffee is somewhere in the middle, where the coffee has a strong flavour without being too bitter.So, while you can get a stronger taste from a coarser grind by steeping for longer, when it comes to a punchy caffeine hit, finely ground is the only way to go! The more finely ground the beans, the more caffeine is released into the water.
What is a standard grind size?
There’s no standard grind size. Coffee beans and roast levels are different, even the same bag of beans will change over time as it ages and degasses. Everyone’s setup is different, different baskets, different grinders, different machines. These all impact extraction. Then there’s taste, which is personal to you. The more pieces you divide that coffee particle into, the more surface area will be exposed (while the total mass of coffee stays the same). So in any brew method, finer coffee grounds will extract faster, while coarser coffee grounds extract slower.Basically, the finer the grind, the shorter the contact time with the water. The grind and the contact time with the water therefore influence each other. If the grind is too fine, the coffee quickly becomes bitter and strong. If the grind is too coarse, the coffee tastes rather sour and watery.
Is bigger burr size better?
Burr size—generally speaking, larger burrs offer a faster and more consistent grinding experience. This is because the larger cutting surface can grind your coffee dose faster with less heat and friction, causing less static electricity and fewer inconsistencies in the cup. Noise and Retention Flat burrs need a bigger and stronger motor that allows them to grind at higher RPM. For this reason, a flat burr grinder is louder than a grinder with conical burrs. Incidentally, flat burrs also tend to have higher grind retention than conical burrs due to this higher RPM.
