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

Need advice to decide between Probatone 12 & Buhler 20
crotzky
Hi all!

I have spent the last few weeks to decide which roaster to upgrade.

Currently I have a 5kg classic drum roaster.

I have two options: Probatone 12 or Buhler Roastmaster 20. From what I understand, those two roasters have different method/style; Probat (Drum Roaster - Semi Hot Air) & Buhler 20 (Drum Roaster - Full Hot Air).

What is the main differences in terms of roasting style & outcome between both roasters? I have no experience on full hot air roaster.

FYI:
- I focus on roasting commercial to low grade coffee, with only few medium-sized clients who are in specialty coffee.
- My current output is 900kg to 1,200kg monthly.
- I have roasted with few brand of roasters in the past: Toper, Joper, Probat, Giesen, Fuji Royal, Yang Chia (But not Buhler)

Hopefully you guys can help me to decide which roaster suit my needs? Thank you in advance!

Cheers!

Before pulling the trigger I would suggest sampling the coffee at a shop using a Loring if you aren't able to find one using a Buhler. The Loring is very similar in that it is fully convective heat and recirculates a % of the exhaust. The Probatone 12 will give you similar results to what you've gotten from the machines you listed in your post. I noticed you've used a Joper which should be half way in between the Buhler and Probatone as it's design (from what I remember) utilizes a power burner and does not apply closely coupled flame to drum.

Edit:

In examining features of the Probatone, it appears to also have a premix power burner as the Joper.
