Should You Grind Coffee Beans All at Once?

In most scenarios, you only have 2-3 weeks once the coffee is roasted to experience it at peak freshness and flavor.
The top layer of coffee (the most exposed) has only 20-30 minutes of peak freshness once it’s ground. The lower levels have longer peak freshness.
For ground coffee, freshness declines rapidly and noticeably after 30 minutes.

You should grind coffee beans fresh every day for best taste and freshness. Grinding ahead will make it stale.
Do not rinse beans before grinding. It will make cleaning difficult and quicken oxidation.

Store roasted coffee beans in an airtight container. Only grind what you will use in the next 15-30 minutes. Freshly ground coffee has a stronger flavor.
Making coffee from pods is more expensive than from beans. Grind beans fresh daily for cheaper, better coffee. If buying in bulk, separate beans into smaller portions for use within a couple of weeks.

For 10 cups (60 ounces), grind 108-120 grams of beans. For stronger coffee, use a finer grind and more beans. For weaker coffee, use a coarser grind and fewer beans.
Conical burr grinders crush the beans and produce a consistent grind. Blade grinders shear the beans, causing a burnt taste. Fresh ground is better quality than pre-ground.
Grind coffee to a medium, sand-like texture. Wet the grounds, wait 30 seconds, then pour half the water over 30 seconds. Pour the rest in smaller increments.
Grinding brings out coffee flavor from each bean. Grinding creates more surface area, quickening oil dilution. So freshly ground coffee has greater oil concentration.
