Dear Weighing my options,
We in the specialty coffee game love using scales when brewing coffee. And we love encouraging our customers to use them too. It’s true. Most people don’t use scales to make coffee though, so why do the professionals?
Professionals in every field use extra tools to accomplish their goals compared to the average person. Think about it, chefs, carpenters, athletes, musicians...… coffee pros, they all use extra stuff that you or I might not use to do their thang. When you’re a professional, there’s just more at stake, heck people are paying you! Things like quality and repeatability are more a part of the process for professionals compared to weekend warriors. Hence, extra gadgets.
What advantage is there to using a scale to brew coffee? Simply put, accuracy. One of the keys to brewing delicious coffee is the ratio of coffee to water. 2 tablespoons coffee to 6 oz of water is a good ratio (keep using that!) but you can get a bit more accuracy using a scale.
With a scale, you can use the same unit of measure, grams, for the coffee and the water, making brew ratios simpler and more accurate. A typical coffee to water ratio is 1:16. If you have 25g of coffee, multiply by 16 to get the amount of water you need, if you have 750 mL(1mL=1g) of water, divide by 16 to get the amount of coffee you need.
Do you have to use a scale? Of course not! But I do recommend it.
*I like the Jennings CJ4000 model, btw.
