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

insulation for the roaster?
kwrcst
Hi all, So I completed my Frankenstein and it's working better than I thought. I did 5-6 seasoning roasts and really put a bronzing on the drum with those oils. I have probably ran 20-30 lbs through it for consumption as well and I am pleased with my results.

Now the big question is how to make it more fuel efficient? Since this is a huge chunk of steel built like a box, you can see the heat rolling off as it roasts. All of the videos I have watched show starting at X% of fuel and by the end you are down to like 30% etc. Yeah, that doesn't fly here. I start with high heat to get to dry in 4-5 min and can't really back off or I lose temp.

My burners are powerful enough to get me there but I think I am losing >50% of my heat retention to the atmosphere because it isn't insulated.

I thought about Kaowool or a similar product but I think I would need to build another shell inside to keep the wool from contact with the direct heat and air circulating into the drum.

I just wondered what everyone else has used for insulation.

thanks

Yes on adding another shell or sheet metal layer to isolate the insulation from the rest of the environment. Not hard to do and benefit is preventing debris from collecting in the fibers and possibly igniting down the road.

Lots of high temp options here and they sell small qty.

lots of insulation choices on eBay. I insulated my roaster with only, I believe, 1 inch of insulation outside of an inner heat shell with an outer cover. I wanted it to be able to get to temp but also wanted it to cool faster too so I would have much more control. The cover does get hot, but so do the end plates, the drive shaft ect. I do not touch any of them.

What I ended up with is exactly what I wanted to accomplish.

I use ceramic insulation from mcmaster.com:

I use the 1/8" thick, but it does come in thicker sizes. It is very easy to work with and cut.
