We’re roasting in Benson

18 July 2019
Benson, AZ

The weather here in the San Pedro Valley of AZ has treated us kindly this year. As Merle Haggard said, “things are exactly as I choose to recall…“, and as I recall 2018, we’d been in and out of the 100°’s a few times before the end of April; snowbirds were gone by the first week of May.

Not so this year. We saw the last of the winter visitors head out about the end of June. We saw our first 100°F day about 13 June… probably 15:00 to 16:00 in the afternoon. Looks like there will be more than coffee roasting for the next few months as summer weather settles in.

Back in June I was hoping luck would be on our side and that monsoons would start by the first week of July (the traditional start). Not so as the clouds struggled to get properly formed and were generally a disappointment. We saw rain in the distance, but the rain never reached the ground. When they finally came, the first 2 T-storms produced all of about 0.01″ of rain each according to our Davis weather station. On about 15 July we finally got a decent bit of thunder, lightning & rain that gave 0.16″ of rain… that’s about 0.19” so far for all of July. Big whoop.

Even with monsoons we still see frequent days of 100°F-115°F before a brief T-storm hits in the afternoon. For us, monsoon rains mean 1 to 15 minutes of hard rain accompanied by strong wind and lightning. Cools off maybe 20-30 minutes ahead of the rain and for maybe 30 minutes after, then the heat is back along with over 60% humidity instead of the usual 5%-10%.

Fortunately our casita has a portal to allow setting up the coffee roaster & computer in the shade. That plus the fixed awning attached to the trailer offers sun protection all day, though outside temps are still so high only a fool would try to work in that heat. Once a T-storm hits, things get pretty wet under the portal & awning thanks to the accompanying wind. In general, anything we need to do outside should be done before 9:30 unless it’s under the portal where I can maybe stretch it to about noon.

Not perfect, but it works.

Btw, the usual population of diehard summer residents is about 85 sites. There are 1 to 2 people per site, so I’m not sure how many souls are actually here dealing wtih the heat… I’ll guess it’s about 125-130. Mmmm… plus the rats, snakes, rabbits and coyotes.

Indulging old habits

1 April 2019
Benson, AZ

For about a year now I have been indulging an old passion- I’ve gotten back into roasting coffee.

We like a morning cup of coffee, probably stronger than most people would care to drink. We had been buying Starbucks unground coffee beans. Benson has very little to offer beyond a WalMart and Mi Casa Restaurant, but surprisingly they have a Starbucks inside the local Safeway supermarket.

Unfortunately the Starbucks beans don’t turn over very fast at Safeway, even during snowbird season. We whined a bit about the morning cup but didn’t do anything about it. Prior to going on the road (in late 2003 I think) I started roasting our coffee first on a tiny hot air roaster (FreshRoast?), then a few months later I bought a drum made by a guy in Charleston, SC. and used a cheap CharBroil BBQ grill to heat the drum. I had the drum mounted on a spit driven by a 60 rpm 1/4 HP motor. We had a lot of great coffee from that setup, but it all went away when the house was sold. And so too did the beloved Giotto espresso machine and the Mazzer-Mini coffee grinder.

The HotTop KN-8828B-2K+ programmable coffee roaster.

So when the Admiral asked if I ever thought about roasting coffee again the answer was a quick yes. I bought a small electric drum roaster called a HotTop which handled just 250 gm of green beans per batch.

This small but sophisticated roaster did a great job. Artisan Software, a free program that could display data in a graph and even control the roast, did an adequate job. But I got a little frustrated on those days when I had to do multiple roasts- I spent twice the time waiting for it to first cool then creep back up to temperature than I did roasting. I knew that Aillio makes a larger roaster with an induction heated drum, but they were updating the design and taking forever to get back into production.

Then suddenly last January 2019 a shipment was announced. I hung out on the Sweet Maria’s site on the magic day and managed to grab one before all 120 roasters were gone.

Aillio Bullet R1. A reasonably sophisticated electric roaster that was designed in Denmark and manufactured in Taiwan.

The Aillio Bullet R1 uses about the same amount of power as the HotTop, but instead of a resistive heating element adjacent to the drum, they use an induction coil to heat the drum. Induction heating has been used for industrial applications since the 1940’s but it wasn’t used in kitchens until recently, first in Europe and now in the US. The reason induction heating appeals for roasting coffee is that it provides rapid changes in temperature instead of the very slow response of indirect radiated heat from a resistive heating element. And the Bullet can handle up to 1 kg of green beans (about 2.2 pounds) vs. 250 gm (just over 0.5 pounds) of the HotTop.

The “Miss Silvie” from Rancillio. These were originally designed as sales awards for top-performing distributors but they were so interesting that Rancillio went into production in the late 1990’s for the consumer market.

Of course if we’re going to have brewed coffee during breakfast, the Admiral also wanted to have a cafe con leche in the late morning. That takes an espresso machine, but an espresso machine is big and uses a lot of electrical power… which there’s not much of on a trailer. But there is a small espresso machine from Italy called a Rancilio Silvie that would fill the bill nicely. I found a used recent model and ordered a PID for it. A PID is a bit of electronics that controls temperature. The kit I ordered was designed and built by Auber Instruments (there are dozens of sources) which replaced temperature sensors and introduced pre-infusion into the brew process (it wets the coffee before it starts pumping water for the shot).

I checked to see what a Mazzer-Mini coffee grinder would cost. I bought ours in 2003 for $365, but by spring of 2018 that cost had risen to $1,150. Yikes!

Initially I tried using our old $65 Capresso, but that couldn’t grind fine enough for espresso. So I did some digging and found a Eureka Mignon that sounded great. Only problem was the grinder design doesn’t handle static electricity very well and the grind comes out in clumps. I was accustomed to turning out really good shots but with this grinder I was turning out crap. I finally accepted the issue was that I wasn’t using the right amount of coffee from one shot to the next and that it was because of the clumping.

The Baratza Sette 270Wi. Choose the amount of coffee in grams and it nails it!

More research. I found a new grinder design that measures the weight of the coffee being ground directly into the portafilter. Sounded slick. The Baratza Sette 270Wi would resolve the uncertainty of how much coffee was being used for each shot for less than 1/2 the cost of a replacement Mazer-Mini.

There were a few negative reviews by owners about the grinder failing, so as a precaution I bought a 3-year warranty from Amazon just in case (something I would normally never do!).

The grinder performance was amazing. Just set the desired quantity of coffee – I use 16 gm for an espresso shot – and within 4 attempts it’s on the money. If it’s off, the error is on the order of 0.1 gm.

After 3 months of really good espresso shots the motor became first intermittent then quit completely. I whined to Baratza customer support and after jumping thru a few hoops to confirm what the problem was they replaced the grinder with a new one. Yay! Back to great espresso shots. But I’m still glad I got the 3-year warranty because having been bitten once I’m still uneasy about long term durability.

So that’s what’s been happening here in Southeast Arizona. That and way too many green coffee beans have come to live with us!

A sidebar…

When I mentioned Safeway above it jogged my memory that I have a bit of a connection to that supermarket chain from 2 generations back. I understand Safeway is now owned by Kroger’s, but back in the days before WW-II my paternal grandfather managed a Safeway store when they were an independent corporation. They were a big presence in the San Joaquin Valley of California. In fact ‘JO’ retired from Safeway and received a small pension. In those days there was no Starbucks and there was certainly no coffee from a grocery store that didn’t come pre-ground and in a can: think Folgers.

This is the entry I’ve been dreading. Today we lost Annie to a combination of cancer and kidney disease. She made it to 11 years 9 months, dieing just 50 days after her sister Kelly. According to the AKC, berners live an average of about 6 years 10 months, so she did good for a berner. But not nearly long enough for a really good dog.

Our two Bernese Mtn. Dogs Kelly (l) and Annie.

They’ll be sorely missed. And it leaves the name of the blog, a dog house on wheels, with a hollow ring. Well, I guess it’s still their dog house, so we’ll carry it on.
