Wacaco Prestina Review
The Wacaco Prestina is a brand new portable manual brewer that utilises a built in cup as the plunger. Instead of pushing a piston through a chamber, you press the cup itself into the brewer. It's a genuinely different way to think about manual brewing, and after spending time with it side by side with an AeroPress Go, I've put together this review on the Wacaco Prestina and got a clear read as to where it earns its place and where it doesn't.
What Is The Wacaco Prestina?
Prestina is Wacaco's take on a plunger-free press brewer. The brewing chamber sits on top of your cup and rather than pushing a plunger down through a separate chamber, the cup itself does the pressing. Inside sits a permanent stainless steel micro-filter, so there's no paper involved at any stage and an integrated duck valve that holds water in the chamber during infusion before opening gradually as pressure is applied.
It comes in Sage Green, Coal Black, and Clay Pink, is priced at $55 at Basic Barista, and ships as a six-piece kit: brewer body, cup, SS filter, scoop/stirrer, carrying pouch, and instruction manual. It's made from food-grade polypropylene, stainless steel, and silicone, weighs around 255g, and packs down to roughly 85mm wide by 134mm tall. There's no battery and nothing to charge. You'll need your own kettle, since Prestina doesn't heat water.
How The Prestina Brews
The process is simple by design. Add medium-ground coffee, pour hot water at around 90°C up to the 240ml line, stir, and let it infuse for a minute or two. The duck valve keeps the brew contained while it develops, then you press the cup up into the body to force the coffee through the filter and into the cup below. Wacaco positions the result as sitting somewhere between a French press and a pour-over: more body than a pour-over, less sediment than a French press.
What I Like About The Wacaco Prestina
The price: At $55 the Wacaco Prestina sits well under most portable AeroPress bundles, and it doesn't feel like corners were cut to get there.
Usability and portability: Everything nests into one compact unit. No loose plunger, no separate filter cap to track down. It's the kind of thing you can throw in a bag without thinking twice.
The colour range: Sage Green, Coal Black, and Clay Pink are all genuinely nice options, not an afterthought palette.
The materials and feel: This isn't a premium, luxury piece of gear, and it doesn't try to be. But it still feels good in hand. The plastic doesn't feel cheap, and the whole thing has a bit of weight and solidity to it.
The carrying pouch: A small thing, but a nice one. It's genuinely useful and something I can see myself reaching for when heading out with the Prestina rather than leaving it in a drawer.
What Falls Short
The included scoop: If you already weigh your coffee on a scale or pre-dose your beans at home, the scoop is dead weight in the kit. It's not a dealbreaker, just an inclusion that won't get much use from anyone who already has a system.
No filter papers: The permanent stainless filter is central to how Prestina works, but it also means you're locked out of using paper filters if that's your preference for a cleaner, lower-oil cup. For some brewers that's a genuine limitation rather than a style choice.
I will note that when I brewed with the Wacaco Prestina using the stainless steel filter doesn't carry through a lot of sediment, there is a healthy amount of oils that pass through but not an overbearing amount.
Prestina vs AeroPress Go: How It Compares
Given the price and portable format, the natural comparison is the AeroPress Go, and testing them side by side surfaced a few clear differences.
- Pressing effort: The Prestina takes noticeably less force to press down compared to the AeroPress Go. Some of that likely comes down to the wider 74mm brewing chamber, though it's also worth noting the seal on my AeroPress Go has worn with use over time, which may be exaggerating the gap.
- Cleanup: Cleaning the Prestina is simple in theory. Pop out the puck of grounds and rinse under a running tap. In practice, it feels a bit more fiddly than the AeroPress. The AeroPress is the more ergonomically optimised design from a usability standpoint, while the Prestina feels like it was built more around the brewing outcome than the day-to-day handling.
- Taste: This was the most interesting part. Comparing the AeroPress Go fitted with a reusable metal filter against the Prestina, the two brews came out very close. Near identical, honestly. The real differences showed up in workflow, usability, and cleanup rather than in the cup.
- Price: The Prestina is noticeably more affordable than the AeroPress lineup, which matters if portability and simplicity are the priority over refined ergonomics.
Grind Size For Wacaco Prestina
The Wacaco Prestina utilises a mesh stainless steel filter, this filter without any exaggeration is by far my favourite metal filter that I've used. It seems to have a warp and weft just like a woven fabric, and multiple layers of stainless steel fibres.
My experience with this has been that the holes catch the particles and hold them back from entering the cup, however the holes are large enough to not cause a reverse pressure making it too hard to plunge.
I've experimented with fine to coarse pour over grind sizes (20-40 clicks on Comandante C40 Grinder) and have noted that the pressure doesn't change too much. With that being said this still is a new unit and I haven't put hundereds of coffees through it.
The takeaway from this is that within reason your grind size shouldn't impact the pressure too much when brewing you wouldn't want to use this like a pressurised AeroPress such as when using it with the Fellow Prismo but you can safely grind coffee on a slightly finer pour over grind size and not feel like you're pushing down against a brick.
How Much Pressure Should You Use?
One caveat that I think is often overlooked in coffee presses generally, is that slower is often better! You should be applying a gentle yet firm pressure down on the brewer. And from my personal experience the slower you press down (within reason) the better the results are taste wise.
A slow and firm pressure feels controlled and gives you time to react if something goes wrong. I have previously used the Prestina with the cap only tightened 80-90% of the way and was able to detect that something wasn't right before the coffee level overflowed. A big part of that was the technique. Slow and steady wins the race here both for taste and control.
Longevity Of The Prestina
While this is a new unit and I haven't experienced these issues there are two things that spring to mind from my experience using other coffee presses when discussing longevity.
The Seal
The soft silicone seal is used to house the stainless steel filter, from my experience this is the first part to wear down and for the moment there aren't any replacements available.
AeroPress know this and sell replacement AeroPress Seals that literally make your 2,5,10 year old AeroPress feel brand new again.
With that said, it's early days and at the time of writing this article we have only just received our first shipment of Wacaco Prestinas and it is likely that Wacaco release replacement seals.
The Duck Valve
The Duck Valve is at the base of the filter, it stops the drips from falling through until you press. it's a soft silicone part with potential to degrade overtime.
The Cap
The cap screws onto the Wacaco Prestina's body, and is used to create an air pocket above the coffee to then press down and force the coffee out into the cup bellow. I have already experienced pushing down way to easily before noticing that the cap wasn't screwed on the entire way. While this could be a potential coffee explosion it was my fault for overseeing this, however with that being said I do feel that this screw isn't 100% lock solid, there is potential for it to wear down over time and became a failure point.
Concerns Around Brewing Hot Water In Plastic
One concern that comes up whenever a coffee brewer uses plastic is whether repeatedly adding near-boiling water is something we should be worried about. The Prestina is made using food-grade polypropylene, or PP, alongside stainless steel and silicone and Wacaco also specifies that the plastic used is BPA-free.
Polypropylene is widely used for food-contact applications, including containers and products designed to handle hot food and liquids. So using PP in a coffee brewer isn't unusual and the material itself isn't automatically a red flag.
With that being said, I don't think it's fair to completely dismiss concerns around heating plastics either. Research has shown that polypropylene products can release microplastics when exposed to hot water and in some studies that release increases as temperatures rise. The amount released appears to vary considerably depending on the product, how the plastic is manufactured, its condition and how it is being used.
That doesn't mean brewing a coffee in the Prestina has been shown to be harmful It simply means that "food-grade" and "BPA-free" shouldn't be interpreted as meaning absolutely nothing can migrate from the material under heat.
For me, this isn't enough to stop using the Prestina. Coffee is only in contact with the brewer for a maximum of 3 minutes at a time and Wacaco has intentionally chosen food-grade polypropylene for the product. But if your goal is to minimise your exposure to plastics wherever reasonably possible, then a brewer made primarily from glass, ceramic or stainless steel is going to make more sense.
Who Should Buy The Wacaco Prestina?
If you want a portable brewer that skips paper filters entirely, doesn't ask much of you technique-wise, and comes in at a lower price point than most alternatives, the Prestina is a solid pick. It's particularly well suited to anyone who already has a coffee routine dialled in and doesn't need extras like a built-in scoop and to anyone who cares about how their gear looks and feels as much as how it brews.
If you're someone who prefers paper filters for a cleaner cup, or you already own an AeroPress and value its slightly more refined day-to-day handling, there's less reason to switch. But as a standalone buy, especially for anyone new to portable manual brewing, the Prestina delivers a genuinely comparable cup at a friendlier price.
