Was that the Geisha from Bailey's coffee roasters? I tried some of their filter roast for that and it was superb.
Leva is a crazy machine, not sure it'll get much commercial use but it's sure impressive.

Cast Iron roasted it, think it was from Morgan Estate in Panama. Guy was saying it's tricky to optimise the roast profile because you can only get really small batches of it.
Yeah Leva looks like more of a showroom/roastery type machine, definitely no good for high volume work. Pretty good design though, I saw other lever machines at the festival and some had the grip ridiculously high up - a shorter person would burn themselves on the grouphead just reaching it.

Had a play on the new La Mazocco Leva at Glasgow Coffee Festival, pretty fun piece of machinery. You engage the lever at the max pressure you want, then hold it for manual preinfusion and release. It then runs a long and slow descending pressure profile as the piston closes off the water flow. You can see it happening as the internals are all exposed. They were pulling a Panama Geisha at 60 seconds, which is ludicrous on paper but tasted delicious.
