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.

03/04/2021 11:35 AM
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

I have a genuine question
I am in the last stages to building a professional home roaster using a 1200 Watt Turbo Oven as a heat source

Its a maths question
I need to know how to calculate the optimum volume of a heat chamber for best use & control of heat
For the fan forced 1200 Watts TO max temp 250 deg Celsius

Many thanks in advance

Extra info
The total roast chamber volume of the new design is currently
Volume
Litre 12.398819 or
US gallon 3.275421
Shape is a truncated cone

Its this shape but you need to view it upside down
www.aqua-calc.com/images/cone_truncated.png

My current roaster has a volume of 16.8 litres
So that makes the new design 4.4 litres less in volume

3D modelling is almost complete & then the next step is to have it built
Once the prototype is built and testing begins I will be roasting test batches, to find its comfortable maximum
It is my hope to get close to a 1 kg roast with the reduced volume

Thanks KK:

I like the degree of roast shots.

I wonder how close they are to others. Anyone else got their own set of roast degree photo's?

An Update
I have calculated by using some on-line calculators (and I hope I'm right)
I will require a max 10 Litre total heat chamber volume to roast 800 grams comfortably
However with some tweaks after testing and insulation I am hopeful to reach 1 kg batches

Once plans & 3D modelling is complete I will be discussing with engineers to produce a prototype for testing

Unfortunately I don't have access (as I once did) to metal lathes to make it myself

KK, do you know whwere I could get a degree of roast color chart that I can print as a roast color reference to record a log of my roasts by

The one from Sweet Maria's is the one I've been using:

Not sure if this helps, Clifford.

Thanks for the reference. I printed the chart at SM and my coffee tastingfriend is bringing some photo quality paper so I can use the photo's as a guide. According to the SM's chart, I roasted into Vienna and lost the bean flavor to the roast flavor. That is why my coffee taster said I was roasting "ordinary" coffee in the Gene. It will roast darker than the Behmor THANKS FOR YOUR HELP --EVERYBODY
