Deep 27: The Selfish Brewer That Saves You Money

I recently completed a two-week odyssey with the Deep 27 flower dripper from Kafek, brewing nearly 30 cups of coffee to truly understand what this unique brewer brings to the table. I've called it a "selfish brewer" before, but in the best possible way - it keeps giving exceptional results while staying completely out of your way. What shocked me most about this compact dripper is how it truly excels at small batch brewing, allowing you to make quality coffee with as little as 5 grams of grounds, something that's challenging with traditional pour-over methods.

I discovered that this brewer's real superpower lies in its ability to help you dial in expensive coffees quickly and conservatively. Instead of burning through 20-gram doses while experimenting with variables, I could achieve the same calibration process using just 5-gram shots, stretching precious specialty coffee bags much further. The concentrated brewing chamber ensures excellent saturation, and the fast filters deliver clean, full-bodied cups that rival larger brewing methods. By listening to this episode, you'll learn why small-batch brewing might revolutionize your coffee routine and discover whether this $30 specialty dripper deserves a place in your brewing arsenal.

[00:00:00 - 00:00:05] We're live right now.

[00:00:05 - 00:00:12] Today is July 22nd, 2025.

[00:00:12 - 00:00:18] We're doing pretty good right now. I think so, yeah.

[00:00:18 - 00:00:36] Just getting straight to the topic. You don't mess around with all the other stuff. Sorry about cursing, but it's all good. This is what we're going to be talking about.

[00:00:36 - 00:01:00] Right here is a Deep 27. It's an interesting name - flower dripper. Call them drippers, whatever you want, but at the end of the day they just brew coffee. I brew coffee and it facilitates everything. It's from Kafek.

[00:01:00 - 00:01:12] They're one of the companies who makes these fast filters - the fast filter revolution and all that. So in this case we're just talking about filters.

[00:01:12 - 00:01:24] I'm taking this off. It's been such a long time since I heard myself. Yeah, we're talking about the Deep 27.

[00:01:24 - 00:01:30] Just finished a two-week odyssey with this brewer. I brewed

[00:01:30 - 00:02:16] four times seven, so close to 30 cups with this brewer in the past couple of weeks. I know somebody could have just told me to try a couple cups of coffee and move on, but I don't do that. You don't do that. You use filters or coffee brewers like this and the reason why I use it is because I wanted to see what it was all about. I've talked about it a couple times, played around with it a little bit. I made crazy accusations against it, telling people that it's a selfish brewer, which it is, but in a good way. It keeps giving, but it shocked me.

[00:02:16 - 00:02:31] The reason why it shocked me is because it truly does get out of the way. You're able to brew coffees as small as five grams in here.

[00:02:31 - 00:02:41] I believe the most that I've tried on it was 20 grams. I think you could even push it to 30, but that would probably be the max in this brewer.

[00:02:41 - 00:02:52] Very concentrated. So once the grounds finally settle into the place that they can, it's very tight, so you know for sure that majority of the grounds are getting saturated.

[00:02:52 - 00:03:08] It's a fast brewer because of the filter and all that good stuff. And that's it really. There's only one real way to pour in this device - you pour in the middle.

[00:03:08 - 00:03:23] You pour in the middle, you do whatever recipe that you want to do. You do one pour, two pours, three pours, six pours - however many pours. There's no need for you to go to the side of the brewer because

[00:03:23 - 00:03:27] the way it's made is very concentrated.

[00:03:27 - 00:03:55] I've noticed - I don't know if it's true, I haven't done a back-to-back comparison with the Hario V60 - but just from what I was getting from these cups, they seemed a little bit more heavy, more full-bodied. But again, it could have been the coffees I was brewing. A lot of them were dark roast, so that could have been just the nature of dark roast. But this brewer surprised me.

[00:03:55 - 00:04:28] It's not perfect. For instance, the way that it's made right here - it's kind of weird because it flares out a little bit, so it's not perfectly uniform. So if you have a bigger cup, you may have a problem putting something on there. But that's the thing - it's not really designed for really big cups. It's a single serve brewer like most brewers. But to me, when I look at a Hario V60, it

[00:04:28 - 00:04:45] looks like it is made for more people. You can make coffee for more people, but in truth, these brewers are pretty much the same. Most of the time we're brewing coffee for ourselves, even if we are making coffee for other people. You can actually do it in this brewer.

[00:04:45 - 00:05:04] The reason why I wanted to come on here and talk about this brewer in particular is because I guess we always come back to the question: do you need this? Do you need another brewer if you have a Hario V60? Probably not. But this brewer is fun.

[00:05:06 - 00:05:18] It's small. The filters are kind of wonky looking - very narrow filters. It's pretty cool though that you can actually do what you want with your cup of coffee. And the reason why I really love this brewer

[00:05:18 - 00:05:37] is because it allows you - I think this is really the saving grace about this brewer - I've never really made cups with less than 10 grams of coffee if I wasn't at the last bit of the bag.

[00:05:37 - 00:05:46] That's just like my go-to. I start with 10, sometimes I go to 20. That's the most that I'll do individually.

[00:05:46 - 00:06:02] But a lot of times I'm making coffee at 10 grams. But now, the reason why this brewer really shines is because it allows you to, with the best of your ability,

[00:06:02 - 00:06:26] make smaller cups. And making smaller cups gives you a chance to actually calibrate the coffee even more. So you can do the same 1 to 15 ratio, whatever ratio that you want to do. I would say 5 grams is probably the least amount that you would want to do when you're making your cup of coffee.

[00:06:26 - 00:06:43] There's something about being able to produce a coffee that rivals your bigger dosages, because sometimes it doesn't scale the same way as you would think.

[00:06:43 - 00:07:17] It's extremely cool because now what you can do when you actually make your cup of coffee is analyze it, change another variable to analyze it, change another variable - and now you're back to only using 20 grams of coffee. And depending on how much you bought of that bag, you're pretty much racing against time, meaning that you don't have that many shots in order to get that coffee dialed in correctly.

[00:07:17 - 00:07:55] This allows you to be as scientific and conservative but in a smaller package. And yes, it is actually in a smaller package. But again, I think the way that this thing really shines is in these smaller cups of coffee. Like I said, you can do a 10-gram dose no problem, you can do a 15, you can do a 20. But when you can go as low as 5 grams - yes, you can do the same thing in a Hario V60, April Brewers, or anybody else - but it's not the same.

[00:07:55 - 00:08:17] This brewer lets you know that I'm here for you for those cups that are challenging, for those cups that you're just really trying to figure out. You're just trying to throw a lot of things at the wall, and this allows you the chance, the opportunity to be there with the coffee.

[00:08:17 - 00:08:39] I think that's the cool thing about this particular brewer. In general, a lot of the brewers are pretty much the same. They have different things about them that make them unique, and what I've just pointed out - those are the unique aspects of this actual brewer. So again, we come back down to this: do you need this brewer?

[00:08:39 - 00:09:07] No, but let's just say yes. And the reason why I say yes, that you need this brewer, is because you'll save a lot more coffee, you'll understand your coffees a lot faster, and the characteristics of the brew is extremely similar to other brewers that are out there that we know of. And if you just want to change it up,

[00:09:07 - 00:10:09] I think the biggest thing about this brewer in particular is that it was fun because I just used this brewer. So no matter what challenges that I had or went through, it just worked. I will say this, as I mentioned earlier, this brewer - you can't get really fancy with it. You just have that single pour method and you pour however many times that you need to or want to, and that's that. So I guess what I'm saying here is that this is a cool brewer. Do you need it? No. Nobody needs a $30 specialty brewer and all that, but it's fun. And if you're already spending a lot of money on coffee and you just want to change it up, go ahead and get it. Like I said, I've had a lot of fun with this. I will continue to use it, and I think it works really well for a lot of people.

[00:10:09 - 00:10:54] Get it, don't get it - it doesn't really matter if you're happy with your coffee. Don't worry about it. If you're just a little curious, it's not going to hurt you if you do. But I think you'll have fun with it because you're probably saving a lot more money using this brewer with coffees that are expensive and you just want to dial it in quickly and effectively. And that's what you can do with this brewer. So the flower dripper, the Deep 27, the Kafek coffee dripper - it's pretty cool. Talk to you later. Bye.
