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

How many pages? Sivetz has tons of info on his website, plus you can watch him live, in person...

Aw. crud. Nevermind. SCAA had their library available to non-members for a while, and I watched a couple of Sivetz videos... alas, it's not free anymore. Sorry.

I've read portions of it over the years and there is some good info in it. As Chad said, you can find quite a bit of it scattered through the net. It might be worth getting it if you can find it for a decent price and would be better having it all in one place.

I'd be interested to hear your take on the book since I really can't remember what the core, roasting specific stuff was like.

If you can settle for borrowing it for a few weeks, your local library should be able to get it through inter-library loan.

There are 171 libraries worldwide that have a copy, including FSU here in Tallahassee. Sweet!

......searching my local library system. Thanks,-Scott

-The 1979 book "Coffee Technology" is an update to the 1963 work "Coffee Processing Technology", and it basically covers the same material with an expanded coffee preparation section. He does not state 'Rule of 15" but he does say the same thing.

Sivetz doesn't exactly compare his roaster to the 1954 Aerotherm (first fluid-bed roaster in production). But he does state the Aerotherm was out-of-production by 1970. Then he goes on to proclaim the advantages of fluid-bed roasting. Among the advantages he states is his roasters are non-heat reclaiming. I agree up to a point. However, I've determined heat reclaiming imparts no off flavor when stopped at first crack. If continued till second crack a not unpleasant slight, smoky, flavor can be detected...

As far as coffee roasting is concerned, I would not purchase the 1979 version titled "Coffee Technology" unless it was either at a reasonable price or for a collection. The 1963 "Coffee Processing Technology" is available free in Google digitized format from University of Michigan download.

In the 1979 rework of the 1963 book, Sivetz expands the 'Coffee Roasting' section by only two pages from 35 pages to 37 pages. One extra page is added to update the continuous roaster section and one page is added to claim advantages for his 'Fluid bed *non-gas recycling roaster'. Most of these claims are included in my previous posted attachment to this thread. The other claim is less tar on the bean. . .

*Note - The Aerotherm did use some re-claimed heat.
