My lovely bride did indeed give the green light, but I hesitate to encroach on my kids' play area. They've completely taken over every square inch of the basement with toys, videos, games, puzzles... the usual kid chaos. An espresso bar doesn't mesh well with that ambiance. At least my espresso gear in the kitchen looks like it belongs. We're discussing a kitchen renovation, which has opened up other possibilities (however lobbying for a dedicate espresso bar in the kitchen hasn't gained any traction).

I've used the Robur at Counter Culture during our regular Friday espresso labs. It doesn't produce the perfectly even distribution of the Versalab M3, but it's miles better than my Mini. Although they both have the same ejection pathway, the Robur hurls the grinds out with considerably more force and the grinds are less compacted by the experience. The grinds "lay out" more easily, perhaps because of the longer grinding surface of the conical burrs (?). Nick used the Kony in competition and said the grind quality is as good as the Robur, but it's a slower grinder (Greg made the same observation). I can live with a few extra seconds. At some point I'll do a thorough side-by-side comparison, if only to settle the issue in my own mind...

I would expect it to perform better than a mini, but how does it compare to a Major. With the larger burrs it blows the grinds out better.

Not being fortunate enough to have a local cafe that lets me play with their equipment (heck, I don't even have a local cafe), I have never put hands on a Kony or Robur. The Kony sounds promising.

You guys with your 18g naked extractions....like the Free Skate at the Winter Olympics. But let's see how well you do in the unforgiving "compulsories". Let's see a naked extraction from a single basket :!:

I won't say it was perfect; there is a slow spot, but it was not too bad. :wink:

Sorry, no videos - but I did dig up some pix.

I don't often pull singles, especially on my Vetrano (shown). Singles were noticeably easier on my Rancilio L7. There's less clearance on the E61 grouphead, and it's hard to avoid overdosing the Vetrano single basket.

Peggy Fleming: The final impression in the cup might make up for imperfections in the performance, as that's the last thing the judges see.

Dick Button: The performance was balky and tentative and lacked flow. The single basket separates the geese from the ducks.

P.S. Peggy's a sweetheart, but Dick can be a real prick.

Would not disagree at all.

Like I said it was not perfect. The extraction was slow and I had a slow spot. Honestly I normally do better with a single although I don't use them often. I will have to take the tripod home and capture a few more over the weekend. It takes a handful of shots to get the grind and dose set.

My lighting sucked as well. What looks like a dead spot in the back right is actually a reflection off the crema from the light I was using, but no excuses.

But I would have been happy to have been served it :!: Your grind was simply off a tad, as you said. Just a smidgen coarser and your puck would have had better porosity. My single baskets demand a coarser grind than the double, and one of the two single baskets, which is taller than the other and has a sharper angle in the conical section, needs a coarser grind than the other single. Tolerances get narrower on the single.

Now, a video-essay on different extractions with different shaped single baskets would be a very nice reference here on H-B :)

Do these machines use proprietary baskets?
