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

Thanks. I might just try a bit fat probe and see if it stays straight.

I have the TC wires shoved into a DMM. Don't know how accurate this could be.

Charged @ 400
TP 45 sec 177
3:50 300
4:38 320
5:12 350
6:00 370
1C 8min 395

I dropped roast @ 10:20-430. My wife likes it dark.

This arrived as did the tubing. https://www.ebay....2569538620 much for instructions , does this need 220v AC to operate? My silicone held up to the heat BTW. Happy camper.

Good to see that you are enjoying coffee roasting

This info from the specs
How to Use:
1.The input is connected with the AC 220V.
2.Output wire is connected to the electric cooker or appliance motor.
3.Turn the knob for speed, voltage, temperature control.

However it may work on 110V as the Voltage regulation range starts at 10V
But someone with more electrical knowledge can answer that better than me

Actually this is "push the buttons" version, instead "turn the knob".
Much easier to reproduce roasts, with knob you can't return to a position with 1% precision, which is 5 C degrees in ET, not negligible.
I would start with empty oven, to find the power value that raise temperature to 270 C, the red line you shouldn't cross.
Also, 175-200 C is an useful range to mark, for the preheat.
During this tuning you will find also the temperature step for a button push, worth to note.
At the end you will find the range you are playing for the roast is not that large as expected, probably some 10-15 steps, in the 60-70 values ballpark, so is for the lids I tested so far.
Thanks you two. I'll try start with our socket current which is 117v just to be safe.

It actually works.

How else... ? Grin

Not sure what I read there... 280 degrees at 60% ? C or F ?
F. I'll dicker with it some more today. Not real pleased with the TC placement. Seems to get banged up where it's at. Beans get stuck behind it. It's also in and out of the beans as the agitator goes round and round. Don't know what the solution for that is. More beans, maybe? Agitator tweeking, possibly.

Did you noticed the picture with my probe placement ?
Yes I did. I'll do some experimentation today.
