But it’s worthy to be perfect. You can buy weight machines to measure your coffee amount.
During the brewing process, you need to be alert on extraction. We have spoken briefly of brewing time but not at the same time though.
Brewing time can be short, like brewing time for espresso is 20-30 seconds. On the other hand, the brewing time of cold brew is a minimum of 12 hours.
But you have to be very very alert on over-extraction and under extraction. Or, it will mess up with your taste.
You need to focus on water temperature while making coffee. Overheat or under heat may ruin your coffee.
For all the coffees served hot, usually, the range of 195°F – 205°F is ideal for them. But you need to be specific sometimes.
Like, 200°F is the best water temperature for French press coffee.
We consume coffee very frequently. Commonly we overlook the small miscalculations we make on making coffee.
But, sometimes, maybe once in a while, we like to taste the ‘Perfect’ coffee. Maybe the weather is too lovely, maybe the mood is too good or may the situation demand.
That time, we need to focus on every detail like grind size, coffee to water ratio, measurement, water temperature, and others.
To conclude, while we try to maintain the best coffee grounds to water ratio hardly, we sometimes forget about other things. You need to remember only the best coffee to water ratio cannot server you the perfect cup of coffee. You have to consider the other factors also.
