  • I have two questions! is it TWO or THREE ounces? Also, what should the puck look like after? does it matter? mine seems to come out very soupy.. does this mean I'm tampering too much, not enough? does it mean the grind is too course or not course enough?

  • @HockeyDiane The overall volume is your choice, really, depending on taste -- whatever you decide on, though, it should be calibrated to come out in that 20 - 30 second window. Soupy grounds could be that you have a machine that doesn't have a pressure release valve or that the grind is too fine or the coffee itself has a high natural moisture content. If you let it sit a bit after the shot, it will dry out for ease in ejection :) - Kat

  • I work in a Fair Trade Coffee Shop overseas and I am having a problem. We got a Eureka Coffee Grinder and it is only spitting out 6 Grams of ground coffee and I would like to have 7 Grams. My boss can't find the operators manual anywhere and I can't find anything on the Internet. I have the fineness correct, and it comes out sweet in the 20-30 second range but the weight is also important. Can you help me, please?

  • @msungs The only model I have seen of these in person had a doser control knob on it that you used to adjust it. Is that not on your model? If not, I don't have any other details, sorry :/ - Kat

  • Great video. Do these tips also apply to superautomatics? For instance adjusting the grind of an ENA? How does the type of roast of bean factor into fineness/coarseness of grind? Thanks.

  • @feds27 Yeah, finer will make a richer shot; coarser less rich. If you use a dark roast, go coarser and if you go lighter, go finer - Kat

  • @SeattleCoffeeGear Thank you Kat.

  • does that mean i'm putting to much ground coffee in the portafilter? if not can u explain what it means to over dose, please

  • @tinbiscuite Yes, it could be that you're starting with too much, it's expanding and then adhering. Try putting in a little less to begin with and see if you still have the same results. You want to tamp it down below the ridge in the basket - Kat

  • i now have what i think is a good grind number for my beans on my Rocky; but when i remove the porta filter from the brew head after pulling a dlb shot the punk a lot of times says glued to the p/f screen?? does that mean i need to grind finer or what?

  • @tinbiscuite No -- but it could mean overdosing, that the coffee is expanding so much it's adhering to the brew screen after the pressure is released. - Kat

  • I have a delonghi ec330 and a bodum bistro grinder. As you've said the bodum bistro doesn't go very fine. I have a pressurized unit so it seems OK; however it was still eluting a little bit fast. I've taken to adding in extra coffee (just filling it as close to the top as I can), and tamping it really hard. I've had a few pulls using this method that tasted much better than my previous attempts (now pulling 2 ounces in about 25-30 seconds). Any tips?

  • @canadabboy Not anything other than you're doing; it sounds like the increase in tamp pressure will make up for the coarseness of the grind, and dosing as much as you can will also continue to help. Short of getting a different grinder, you're probably doing all you can for your shot - Kat

  • o.k. once agian. my Rocky is about 4 days old and the grind tamping or silvia is off.

    this morning i dialed in 7 on the rocky. it took 9 secs for the 3 oz! Relative humidity was 100%. should i dial in a finer grind; tamp even harder, clean silvia? i'm stumped.

    thanks for any help Kat.

  • @tinbiscuite Definitely go finer; test your tamp pressure on a scale if you can to make sure you're being consistent about that. Does 100% humidity mean you were doing this in a pool? ;) - Kat

  • From watching these videos, it seems most of the time the grind is way too course or rather, you're trying to conserve time on your videorecording!

  • @joeldamianicigan We try to show all the different variables. Also, rarely are any of our grinders dialed into a specific machine, so often require tweaking. - Kat

  • Kat & Gail- Thanks so much for the videos- very helpful to a noob in the home-barista field.

    Q- I noticed that when Gail does her grinds the coffee comes out fairly centered in a nice neat pile in the pf, however when I am doing my grinds, the coffee fills the right side much faster and I have to do that little rattle/tap in the pf bracket to move it over to help fill the left side, or stop mid-grind and poke at it. I know the exit hole on Rocky is a bit off-centered, but any other solutions?

  • @cestusjr1 Not really; all of our grinders do this differently and I find that I'm always shaking/evening out as the grind is occurring. Gail does this less than I do, but it depends on the grinder. Sorry, wish I had a magic bullet for you :( - Kat

  • my problem is that i grind coarser and then it wont tamp into the pf so much so the silly screw on the silvia hits the puck real bad ?? what to do kat ???x x

  • @92benjy Dose less? - Kat

  • These videos are so helpful to us home-baristas starting out. Thanks all the way from Sweden!

  • @Starslope You're welcome! Glad you're finding them useful :D - Kat

  • wait.... in the video that asks how many ounces are in a shot, gale says one ounce per shot, but in this video, she says a double shot is 3 ounces. which one is correct?

  • @jayrmartinson It's anywhere from 1 - 1.5 oz, depending on your personal taste. It will vary, depending on who you ask. I pull 3/4 of an ounce for my shot, Gail pulls 1.5 oz., others pull 1 oz. The overall volume will be a combo of your personal preference + the specific coffee you're using and how well it stands up to length of pull. - Kat

  • Hello Kat, thanks for your quick response. I'm now going to try the grinder settings. I see good espresso's here on YouTube, mine are not so good, soo I give it a try!

  • @mickdehond You will get great ones with that combo, just takes awhile to get the technique down and then you'll amaze even yourself :) - Kat

  • Hello,

    I love this video's. I've bought an Silvia last year and yesterday bought an Rocky. I've choosen for the Rocky with doser. Now I've seen your video's I'm asking myself if this is a good choice. Is doserless better? Greetings from the Netherlands! Cees

  • @mickdehond It's not really that one is better over the other, their grinding function is identical..so it's personal preference. Some folks like that they can grind with the doser version & walk away...others like the on demand of the doserless. They're both great grinders; are you grinding for multiple shots at one time? If so, the doser is a good choice. - Kat

  • 2:39

  • @eatingperson I wish I could transcribe that! :) - Kat

  • Thanks for your answer Kat, however I ran into something strange.

    The burrs from my Rocky seem to touch when I set the dial any lower than 9.

    So I would say I would get the finest grind the Rocky can grind at at 9, unfortunately I think the result I'm getting is still too coarse since the coffee is coming out too fast (I also compared the grind I'm getting, with the grind I bought at a local coffee store. Which they grind at their 'La pavoni-setting').

    Thanks a million for helping me out!

  • @Tjuust We see this from time to time, that the sticker placement on the hopper is off compared to where the actual burrs' 0-point is. I would definitely have it looked at, though, because you should be able to use that grinder on the Pavoni; we have. - Kat

  • @Tjuust Yes it seems to be a common thing its just the label with the numbers doesn't line up and everyone is stuck on differently mine is set to 4 which seems quite low but i can go down to minus 3 on dial its just for reference no 2 will be the same

  • Great video! I recently bought a Rocky as well and I understand the timing of the shots, but I am using a La Pavoni Europiccola.. Do you girls have any suggestion on how to find the right grind since I can regulate the extraction time by pulling the lever fast or slower.

    Thanks very much!

  • @Tjuust I would still dial in the grind based on the extraction timing you want to use -- your natural force. You still want it to come out at the same rate for the extraction, so determine what pace you're going to use for it (since you're the pump) and then adjust the grind to meet that. - Kat

  • @SeattleCoffeeGear Thanks for your answer Kat,however I ran into something strange.The burrs from my Rocky seem to touch when I set the dial any lower than 9.So I would say I would get the finest grind the Rocky can grind at at 9,unfortunately I think the result I'm getting is still too coarse since the coffee is coming out too fast (I also compared the grind I'm getting,with the grind I bought at a local coffee store.Which they grind at their 'La pavoni-setting').Thanks a lot for your help!

  • Kat...when you time a shot..do you start timing from when the you throw the switch to start the pull..or from the first drop?

  • When you initiate it -- as soon as you turn it on, start counting from there. Ideal would be for the shot to then start coming out at the 7 - 10 second mark, fully extracting in the 20 - 30 second area, depending on your taste. You may have to adjust this a little bit if you're pre-infusing, and these are just general rules of thumb that are flexible based on your own personal taste. - Kat

  • outstanding video

  • Thank you! :) - Kat

  • Hi

    I have brought a Rocky grinder less than a week ago so still playing around with it. I have a concern that worries me. I think I have found the right dial for espresso (12) but worried that the burrs start touching at number 10. If I wanted to go finer with the grind I would be in trouble. Would you say I had a faulty grinder? Also when I fill the portafilter be it single or double and tamp to the line it weighs in a lot more than the 7/8 grams what you are meant to have. Any advice pls

  • If 10 is your actual zero point, then it could be that the grinder might need to be recalibrated. If you bought it from us, give a call in and talk to a tech to troubleshoot it. Shot volume can vary from 7 - 10 grams per shot, depending on personal preferences, so your double will be anywhere from 14 - 20 grams. It's more effective to weigh this out in bean form before grinding, I've found. - Kat

  • If you had a shop in London I would have been happy to buy from you with your experience. I watched your vdeo on cleaning the rocky and you mentioned recalibrate. What does that mean ?

  • Ah - okay. Well, recalibrating will be dialing it in; after you're done cleaning, if the burrs were caked with coffee, then you likely had to grind at a different level. Now that the burrs are cleaned, you'll need to dial it in again -- time your shots, etc., so that you are grinding at the right level. I would contact who you purchased the grinder from and talk with them about your zero point, see if they can't tweak the grinder for you to give you more room to move. - Kat

  • Question: At 55 seconds in this clip, Gail says a double shot is three ounces...did she mean two ounces?

  • Yes - and this is a debated subject because it depends a lot on personal preference. Standard shot is 1 oz; a ristretto is around .75 oz and a luongo can range from 1.25 - 1.5 oz. - Kat

  • Girls I need your help.......

    Got Silvia and just got Rocky but can get my shots at 30 secs below dial 14. Do you think Silvia is broken; maybe tamping? I have a tamper with a curve; is not flat, could that be it?

  • Sorry, I'm not clear on what's going on here -- is it coming out too fast or too slow? If your grinder is at 14 and you're getting the right extraction rate (starting at 7-10 seconds or so and extracting a double shot in 20 - 30 seconds) then you're fine. The grinder just has a lot of room to move, which is awesome -- that means you have more grinder options as the burrs age. Please feel free to msg me here if you want to troubleshoot, I have limited space in the comments. - Kat

  • Actually the shots are coming just right with lots of crema. It has that Guiness effect. But since I always see you girls use the setting at 10 or so I got concern. Thank You ;0)

  • Oh no - every grinder is going to be different. That's why you need to do the timing/calibration and we can't just say 'put it on x number for x machine' -- if you're getting good results at 14, then you're good to go. Kat

  • Gail/Kat..I have my grinder dialed in so that it takes 4 secs for the first drops to come out. Thing is...I have little or no crema!! If the timing is ok..is it my tamping? Help!

  • Try calibrating so it doesn't start coming out until 7 - 10 seconds, and watch for the flow, it should be consistent. Crema will also be defined by the coffee you're using and how old the roast is. You could try updosing and or going finer with a lighter tamp, etc. - Kat

  • Kat...I have a Silvia, but I use a Dualit Burr Grinder. I have it at its finest setting, I tamp at 30lb..the coffee beans are high quality and freshly roasted only two days ago at Edinburghs best coffee shop..yet I have no crema...I will try your suggestions but do you think the grinder I have may still not be grinding fine enough?

  • I think that it's not grinding finely enough and it's coming out too quickly as a result. The lack of crema could indicate an underextraction. - Kat

  • Kat..I now have a Rocky, to go with my Silvia ! However, following exactly what Gail does in the vid ie. set the grinder to 10 with my usual tamp, which I think is a pretty steady 30lbs...i dont get a drop. However, setting Rocky to 13 and its pretty ok. My question is..would the difference maybe be down to he fact that my Rocky is brand new? I was sorta expecting that I coul set it exactly the sameas in the vid, with the same results!

  • No, every grinder is going to be different. Follow the process in this video -- timing your shots, etc. -- and that will determine what your grinder should be set at. It's going to vary by grinder and the kind of coffee you're using. - Kat

  • Great video. I own a rocky and and silvia. I need to set my rocky to 4 (4 clicks from the point at which it can't turn any more) which is very fine. If I don't it just pours out. I tamp really hard(much harder than you) is there something wrong with my machine or is it the temperature of the machine (i do temperature surf it). If you or anyone has any ideas I would love to hear

  • Doesn't sound like there is anything wrong with it, your grind is going to be defined by the coffee you're using, too. I would clean the burrs and find out that is having an impact as well. - Kat

  • Great Video, It will help me a lot now that i'm learning.Thanks girls.

  • Kate and Gail, plzz can u do for me the same video with mazzer mini grinder and rancilio silvia. i wanna know more about mazzer mini grinder. i just recently bought it from ur company and your videos are very helpful to me. please reply back thx

  • Hi there -

    The process is the same for any grinder and machine; you choose a setting, grind and tamp and then pull the shot and time it. Depending on how fast or slow it's going, you'll adjust the grind accordingly.

    We will be doing a video on the Mazzer mini that will talk about functionality, so maybe that will answer some questions. If you need some detailed assistance, you can always call in -- we do provide training over the phone :) - Kat

  • Thank you, and i will look forward to your video :)

  • Not so much for myself, but as I'm sure others would find this useful, I would love to see you guys cover grinder maintenance and set up; e.g. cleaning burrs, dosers, etc.; checking burr seating, calibrating to true zero and backing off from there, using grindz, examining older burr sets for wear or pitting from foreign objects, replacing burr sets, maybe cover grind retention, etc.

    You know... all the good stuff, as the grinder is one of the most important parts.

  • Great suggestion! I will add it to our list. I know we've covered some of this stuff in other videos and so maybe we'll pull a comprehensive one together. Thanks! - Kat

  • You guys are the best thing going in the way of propagating information about home-barista oriented espresso machines on YouTube. I keep coming back to these simply because they're fun to watch and you're very responsive in replying to comments.

    Rock on...

  • Rad! Glad they're useful and fun :) We do take requests, so feel free to message me here if there's a question you have or a demo you'd like to see. - Kat

  • Comment removed

  • Hi. I am enjoying your great clips. I have purchased a Mini Mazzer and it's on the way. What is the set up dial (average) for mini mazzer? My machine is also Rancilio Silvia V3.

  • Well, since this is a grinder with infinite settings, I would load it with beans, turn it on and then start adjusting the grind down until you get to a granulated sugar consistency, no clumping. Throw away those grounds and then start your dialing in process from there. Feel free to email me here if you need more guidance - Kat

  • Kat, thank you for the quick reply. I just received my Rocky grinder and Silvia v3 and I'm trying to dial it in. Still working on it.

  • Gail or Kat, what kind of coffee are you using in this video?

  • We're using Lavazza Super Crema - Kat

  • what type of tamper is that?

  • You know, I'm not sure. We don't have them for sale, it's just one we use in the store. Let me check with Gail to see if she knows the brand and I will follow-up later this week. - Kat

  • OK - it's an unbranded sample that we got awhile ago but don't carry or have access to anymore. It's just a basic 58mm with a polished wood handle.

  • I actually thought my grinder (Compak K3-Touch) was broken on delivery because when I set it to pretty fine on the dial (about 2/3 to the left on the rotary dial thingie) the grinder would just come to a halt. Took a while until I figured out that I had chocked the grinder and that I couldn´t rely on the dial scale at all. Had to make my own on a piece of paper and tape on the grinder :) Works like a charm now though!!

  • Yeah, these are generally just stickers, so we have run across the 0 point being quite different than 0 every now and again :)

  • nice video you guys, thanks for the clarification.

    i set mine to level 6 and i put a bit less coffee and tamp lightly , seems to work with my X5

    this got me thinking , i want to try a 9 level like u guys did and maybe fill up the filter with more coffee and tamp a bit harder

    will see how that goes

    keep em comin :)

  • Let us know how that works out!
