Brewing coffee is an art or science?
1 of the questions from my instructor during the first day of my 1st Degree of Coffee course.
What I learned… something far away to think about would be from the origin of the beans at different altitude, temperature, soil, rain/water all the way to blending (single origin, trio etc) and then roasting. To me they are mostly part of chemistry, so they are science.
Of course, you may say skillful workers picking and shortlisting the beans, skill or roasting etc are art. Yes, I do agree with that too, but a large of them are still science that created the SOP for workers to follow.
Unless you roast coffee beans yourself, most of the mentioned activities are usually beyond our reach. Let's talk about something that we can do…
I would say brewing coffee is both science and art.
I usually do with dose of 20g, yield 40g, between 20s and 30s. These figures are actually Science. Even the type of milk (different brand, lactose free, almond milk etc) would make a difference. Of course milk pitching positioning too… these are science. Btw, I use an average of 4 liters milk each week. My 'regular client' (wife :-)) wants lactose free or almond milk too… They all (diff milk) work differently.
This is like cooking recipe, if you don't follow the given volume of spices or materials, you are not going to get the chemical effect that you want.
What about Art? Undoubtedly Latte art is art :-p
Let me use this analogy to explain more about art…
A very good char kway teow cook is getting too old and decided to pass the business to his only son who had been his helper the past 10 years. The father is given the full including secret recipe but the son just can't cook out the same delicious taste like the father. The secret recipe here would be the science. The art would probably be the way his father massages the kway teow, the strength and gentleness the father stirs and handles the wok, the pace the father puts in ingredients and the heart the father uses.
From there, we can tell that the science is really the recipe, which in cafe's world is very much like SOP for brewing coffee. As for the rest of the things are the art part. I stand corrected. Please feel free to share. Thanks…
