Coffee Brewing And Extraction Yield

Описание: In today's video, Michael talks about coffee brewing & extraction yield. He explains what it is and how to measure it. Just by knowing how to calculate extraction yield will help us improve our coffee roasting and coffee brewing skills. Last week we talked about how brewing is the process of extracting coffee compounds from the beans. Today we want to focus on the concept of measuring the amount of compounds we take out of coffee when during the brewing process.
We use time and temperature measurements when we roast coffee. So, just like roasting, we can measure and track data within our brewing process to improve the results and we do this through a couple of ways including refractometers and our palate. Refractometers can help us measure the TDS and present a calculated number. We can also detect brewing defects (over extraction or under extraction) using our palate. Have you used a refractometer? Do you measure Total Dissolved Solids when brewing coffee using either a refractometer or your palate? Share your comments below!

I roast coffee on my Mill City 500 gram commercial coffee roaster every week. I also use a Behmor and a hot air popcorn popper to roast some great coffee. Join me as we roast, brew and cup coffee at home here at the Virtual Coffee Lab YouTube Channel.

Do you roast coffee at home? Do you craft single serve coffee and if so, what brewing method do you like? Please share your comments and be sure to like this video!

About Me:
I am a coffee enthusiast who roasts coffee from home on my sample size commercial drum coffee roaster. Coffee has been in my life for over 40 years, whether I was selling it or roasting it, I want to share my passion with you.
