I have been trying Scott Rao Hario V60 pourover this week. 1:17 and blooming with 2 parts water the first 45 seconds then splitting the rest into 2 pours. A little stirring is included. We like it.

My brew ratio is 1:17 (exactly 59.5 g/L). That's roughly 8.5g per 5-oz cup.

I'm looking to hire someone to teach/help me to find the best roast profile for the 3 types of coffee that grow on my farm in nicaragua. I live in LA, but but could go anywhere in so cal with my Behmor for a roasting lesson. Please contact me if you're in

When your wife thinks 30 grams for a 6 cup setting is strong, you learn to drink muddy water when you are making coffee for both of you.

I use a rule of thumb of 60 grams per liter. 8 cups (1 liter, 32 oz) = 60 grams, 6 cups (3/4 liter, 24 oz) = 45 grams. 10 cups = 75 grams 12 cups = 90 grams

Tastes/Aromas Flavor Wheel
New thread for Scotts post concerning "Tastes, Aromas" versus chemical compounds.

Can someone move these posts to this thread?

There are 2 parts to the flavour wheel

However this site is a beauty that lists many smells and a great resource

Also important is the tongue

Two taste chemical tidbits:

There is another taste that's been added to the four we learned in grade school, pictured above. It is called umami. Its a flavor produced by foods high in protein. Think meat broth or unsalted soy sauce.

There are hundreds of chemicals in coffee. One that highly influences its flavor is trigonelline. It helps to give coffee its bitter taste. As coffee is roasted, trigonelline decomposes. That's why dark roast coffees are mellowly than lighter roasts. Lengthening the roast by drawing out the profile will result in less trigonelline and alter the flavor.

Now this thread is up to date. I couldn't figure out how to move actual posts.

Tom and Maria's Tiny Joy has this issue as their focal point this month.

You can see it at Sweet Maria's.

Thanks for posting this flavor wheel; very helpful to me as a newbie. I found this narrative to go along with it, a pdf file:
So many beans; so little time....
