We recommend neither the Primula Burke nor the Cafe Du Chateau as cold brew coffee makers. Both fell short of our testing criteria for different reasons – the Primula because of its flawed filter design, and Cafe Du Chateau for its poor design quality.
Overall, though the Primula Burke is well-designed, its plastic and nylon filter is too fine for a decent brew to develop, and the materials used also mean it is not a great choice to double up for hot brewing. Therefore, the device has limited practical use.
The Cafe Du Chateau, on the other hand, is an attempt at a repurposed French press design. It fails because the glass carafe is heavy and bulky, poorly weighted for a steady pour, and the stopper is either too tight or too loose. Its brew quality is average, but the device itself is not a pleasure to work with.

Bouquet
The bouquet of the Primula was decidedly on the weaker side. It was light and sweet but our testers did, however, pick up a faint roasted note. This indicated that the brew was probably sub standard.
After 18 hours of brewing, the Cafe du Chateau produced a noticeably weak bouquet despite a reasonable brew ratio of 1:8. The bouquet did, however, have a distinctively earthy note. Overall, there was very little complexity and sweet notes were indiscernible.
Drinkability
With a typical one-to-one dilution, the final drink was very light, watery, and somewhat sweet. In fact, even without dilution, it was still watery with little complexity. There was a slightly sour aftertaste, so not so satisfying. Although the brew is drinkable without dilution, it lacks excitement or complexity, which also means that the Primula is uneconomical for the amount of coffee ground used.
With the Primula, we would suggest a longer brewing period or brewing at room temperature. Either that, or using the hot blooming method to get a more substantial and richer brew.
Considering the brew ratio, we diluted the concentrate with one part water to one part coffee. The final serving was smooth to drink, but the aftertaste was neither rounded nor satisfying. It had a defined roasted and somewhat earthy flavor, but lacked character. Overall, the Cafe du Chateau produced an average to reasonably good brew, but it didn’t excite.
Sediment
Having to filter a large quantity of liquid means cold brewing can be time consuming. Convenience, however, comes at a price. Our repeated testing has found that the permeability of an immersion filter is key to producing a quality brew.
The Primula recorded very little sediment, which at the same time betrayed its fundamental flaw. The filter, as good as it was, lacked the permeability to produce a worthwhile cold brew coffee concentrate. In this case, the cost of a perfectly filtered brew was the quality of the brew itself.
After allowing the concentrate to settle, we decanted the contents of the Cafe du Chateau. The filter, made of laser-cut 304 stainless steel, did a good job overall. There was not much sediment and it was mostly fine with some powdery grains. All considered, the filter seemed not porous enough to produce a high quality brew.

Primula Burke Deluxe Cold Brew Decanter
- Height With Stopper Lid:7.9
- Base Diameter:4.7
- Width:7.4" (18.8 cm)
- Weight:19.5 oz (553 g)
- Material:borosilicate glass & plastic
The decanter or brew carafe is made of thick borosilicate glass and enclosed in a plastic jacket. The jacket doesn’t detach and also forms a base cushion. While cleaning, we noticed that there is an additional silicone seal on the base of the decanter.
- Height With Stopper Lid:9
- Base Diameter:5
- Width:6.5" (16.5 cm)
- Weight:29.5 oz (836 g)
- Material:borosilicate glass & stainless steel
The brew decanter has the look and feel of a solid and durable product. However, on closer inspection it’s not without its flaws. For one, we found it a bit on the heavy side even when empty. We filled the decanter with water to test pour it, and it poured rather heavily. It also felt unbalanced and the grip was somewhat slippery. The manual says the glass decanter can detach from the stainless steel sleeve, but it was difficult to do, so we left this for the cleaning stage.
Stopper / Lid
- Diameter:4.9 in (125 mm)
- Material:plastic
- Additional Features:open/close function, silicone seal
The lid comes in three parts. The outer section has a silicone seal for an airtight fit. The filter attaches to the bottom and you simply press it into the carafe. With the inner lid removed, you can easily pour in the water and then seal the carafe for brewing. When storing decanted coffee, you can open this lid to stir the contents before pouring. To pour, you turn the lid handle to the open spout position.
- Diameter:3.9 in (100 mm)
- Material:stainless steel
- Additional Features:silicone seal
The stopper has an airtight when brewing, but is rather loose with the filter attachment removed. Furthermore, the silicone seal is very rubbery, deforms easily, and is overall not the best quality.
Filter
- Length:6.7 in (170 mm)
- Diameter:
- Material:polypropylene and nylon mesh
- Additional Features:detachable base
The filter is solid and well-made. In terms of design for a cold brew coffee maker, the plastic jacket appears to be limiting. It is uncertain how much permeability this kind of filter design will allow for proper brewing. In test brewing, we found the filter design to be fundamentally flawed.
- Length:6.7 in (170 mm)
- Diameter:4 in (102 mm)
- Material:laser-cut 304 stainless steel
- Additional Features:silicone seal
The filter is made from laser-cut 304 grade stainless steel and comes with a ‘lifetime warranty’. It appeared well-machined and the edges were not sharp. However, like the decanter lid, the silicone seal around the filter top was not such great quality. The filter, however, did allow for a relatively decent brew to develop and the sediment produced didn’t require additional decanting.
Build Quality
Overall we love the high quality of the materials and the convenient design. The mid-range 1.6 qt capacity is also very convenient, and we like how the brewer is wider rather than taller. The only fault is not so much the build quality, but rather the ill-conceived design of the filter.
The materials used, except for the silicone seals, are generally good quality, however, the design is not well executed. The brewer is all-round cumbersome to handle, the lid and seals are poorly designed, and it is weighted badly for pouring. Overall, this has been one of our least favorite cold coffee brewers to work with and will probably gather dust on the shelf.

Brewing
The Primula filter takes around 3.5 oz / 100g of coffee grounds, which means about an inch to a half below the filter rim. After securing the filter onto the outer lid, you insert both into the decanter. Next, pour enough water to wet the grounds. After a couple of minutes, you slowly continue pouring water until the rising water hits just below the top of the plastic jacket. That’s about 40 fl.oz (1.2 L) or 6 measuring cups. Finally, screw in the top lid so that the spout is also closed.
The brew decanter can sit in the door of your average 33- or 36-inch refrigerator but may be too big for an apartment-sized refrigerator. Brewing was relatively straightforward except for the lack of markers on the vessel. We also found the full carafe to be a little heavy. It weighed 4 lbs or 1.8 kg, so make sure to grip it firmly and avoid letting children handle it.
Like its design, brewing with the Cafe du Chateau has its unique points. No measuring is required because you just fill the filter with grounds to about 1 cm (less than ½ inch) below the top.
Then, you gradually pour water through the grounds but you don’t push the filter completely in. The filter has an upper chamber which makes pouring water very easy. The filter itself is very fine so you must wait for water to seep through. The last 200 ml of water takes a little time to pour.
Once the water is just below the 1-liter mark, you push the filter unit completely in and do the same for the lid. Despite the cumbersome design of the silicone seals, they do a pretty good job. Most air is completely compressed out of the brew decanter. All in all, the brewing method seemed very sound and we looked forward to the brewing results.
Decanting
We found that decanting worked best by simply lifting up the outer lid with the filter attached. Because the base of the filter is not permeable, it’s best to let the filter stand in a dish as quite a bit of extra brew still trickled out.
You can immediately remove the filter from the lid. We found a few granules of coffee had gathered around the edges so it’s best to completely rinse off the lid before putting it back. Once again, make sure the spout is closed to prevent coffee odors building up in your refrigerator.
As with all similar immersion brew filters, all we had to do was remove the filter and place it in a glass to catch the remaining liquid. The stopper comes off with the filter attached. To separate the stopper, you’ll need to hold the filter tight, twist and pull forcefully.
Additionally, the decanter lid doesn’t fit so snugly when the filter unit is removed.This means that your fridge may become contaminated with coffee odors and the concentrate may oxidize and spoil faster.
Once the filter and grounds are removed, you should have around 700 ml of cold brew coffee concentrate. The overall volume is 900 ml (30 fl oz) with the difference being taken up by the filter and grounds while brewing.
Cleaning and Storage
Cleaning the Primula is effortless all round. It separates into seven parts. The filter parts and the lid can go on the top rack of a dishwasher while the decanter on the lower rack. It’s probably best to just rinse off the silicone seals. While cleaning, we discovered an additional seal at the base of the decanter. The plastic padding on the base gives a comfortable feeling when placing on the table, and peace of mind when storing away. We loved the quality of the decanter, except that it can be heavy for some when full, but the grip and pour is good.
Cleaning the Cafe du Chateau filter is easy enough. Use a standard non-abrasive sponge. You can reach to the bottom of the filter and the edges are not sharp. The decanter itself is easy to reach inside.
The user manual states the glass decanter is fully removable from the stainless steel jacket. Even after running under hot water, however, we were unable to remove the decanter. We didn’t want to exert too much force and break the glass, nor injure ourselves, so we didn’t succeed in separating the parts.
All components except for the silicone seals can go into the dishwasher.
Once dried, the brewer can be stored fully assembled. It looks nice on a counter and should easily fit in a standard cupboard or a shelf space. The filter also stands well on its own for storage when the decanter is in use.
