From a technical perspective, it looks like they are cycling the pump on and off to create pressure profiling and control pre-infusion. How many start/stop cycles will the pump endure (meaning add to premature wear and tear)? I do not think they are controlling the voltage to the pump. If they are, how low can they go? I do know at 55 volts, ULKA vibration pumps will not operate.

Posted April 29, 2013 link

jim, it's certain breville isn't controlling the Ulka's output pressure by varying voltage.  These pumps, as you implied in the second sentence, are not very tolerant of varying voltage, that's why folks using Variacs (or worse: cheap dimmer switches), to attempt to profile the Ulka report less than stellar results.  it is much more likely that breville's controller is clipping selected apexes off of the sinusoidal A/C voltage to the pump.  I _think_ that's what Bill Crossland is doing, too.

unrelated:  I see the VST marketing machine has gotten it's hooks into the newbies again.

Wow, technical stuff this CPA just doesn't get.  But thanks for sharing. LOL

I've recently returned from using exclusively the VST basket in the naked PF to the stock basket and spouted PF.  My technique has improved greatly since I first got the BDB so I'm comfortable that I"m getting good shots without having to diagnose each one as I can with the naked.

I notice that I can turn the grind a little coarser but little other difference beyond less spritzing when I don't have things just so.  The problem I have is the recommended dose from my chosen roaster is more often than not 20g which just won't fit very well.  The VST seems to hold that little bit more better, probably because of the straight sidewalls.  I have to reduce to closer to 19 which does change the profile a little.

Subject: RE: VST baskets
 

Peter, I gotta say the Breville 18gm baskets are excellent baskets. In many ways they are better than a lot of commercial baskets of the past. They are a STEAL for $9 a piece. I feel like recommending them to my wholesale customers.

Still, they are not as heavy and versatile as the VST baskets. When a roaster says his/her coffee is best at 20gm doses, 40gm shots (or whatever) then you just can't do that with the stock 18gm basket. You certainly can't underdose them much either. I can do 14gm in a 15gm VST basket and get good shots. Messy pucks, but excellent extractions.

Have you seen some of the baskets out there? They feel like cheap tin, the group of holes aren't centered and they are no where near consistent in size. When you have two or more groups on an espresso machine it is very important to have baskets that behave the same. VST baskets do this. And yes, we can taste the difference. Are they worth $30/ea (or even the $20 on sale)? That's up to you, the individual. If they last for years in a shop, then hell yes.

Like I said, I love the Breville baskets for what they are. They (and the dispersion screen) are very high quality, never mind on a machine in the 900's price range. They are good enough that they will never be the weak link in any given espresso shot. Unless you try to under-dose them :)

No, I don't own stock in or benefit from VST at all... I only make money from selling roasted coffee.

oh man, this should be 1 of the things they have to consider i mean, we dont just stick to 1 blend or 1 single SO, we explore different coffee and different roast, and sometimes checking the flow rate and weight just drives that "oh what was the shot time?" hehehehe

I have noticed that to my taste preference the 15g suits me. but the single basket is too small and the double basket doesnt allow me to tamp 15g. so ive decided to get the vst (recommended basket than others) for its straight wall so i can tamp 15g.

the baskets hasnt arrived yet, so i will see how the shots are if im able to tamp 15g.

I have tried 16,17,18,19g at 195 but they are a bit bitter in gradual unlike the 15g that suits me best.

and since the mail can accommodate 2 baskets - i just took the opportunity i mean i have to ship those stuff here in the philippines, so you know what i mean. so was asking people here if anybody tried the 20g if it fits the stock pf.

The VST 20 gm basket will fit the regular portafilter.  Currently I use it on the naked portafilter.  I have the ridged version and have replaced the Breville springs in the portafilter with Rancilio springs ( available from Seattle Coffee gear).  I snap the filter basket  in and out easily with this setup.

need some advice, I was just taking the tip of the steam wand off to clean/soak but I dropped it on my (tile) floor, doesn't seem to be any physical damage but should I get a new one just in case?

Honestly, I'd worry about the tile before the steam wand. Just clean it off/out and see if it threads back on easily. The pipe that leads to the wand would be the weaker link in that chain. If it didn't thread on easily then I say get a new one.

Glad you found it. I dropped my screen screw into my disposal. That had me worried. Luckily it's magnetic and I had a little flashlight with a magnetic base to pull it out. The disposal was magnetic too, so that was a little more challenging than you might think.
