Making Coffee - the basic fundamentals:
1. Choose a device. Aeropress, V60, French Press, Auto-Filter Brewer, Espresso Machine.
2. Get a grinder. Even a cheap hand-grinder will be better than buying ground coffee. Make sure it's a burr grinder and not those with blades.
3. Buy fresh roasted coffee BEAN, not ground. (Roasted not longer than 2 months)
Freshly ground and freshly brewed coffee is the way to go.
While sipping your lovely cup of coffee, stay humble and stack sats.
