The Primula Burke, despite its thoughtful design, fails as a cold brew coffee maker because of its oversight in the filter design. The fine polyester-type mesh of the filter lacks sufficient cross flow for a decent brew to develop.
It has a glass body with a plastic jacket and the lid is well-designed. The lid simply twists to pour or you can remove the inner core to insert the filter or stir the contents. The County Line Kitchen excels with its screw-on plastic lid with a flip cap for pouring. You can also choose a lid with a handle or one without.
That said, the County Line Kitchen produces an excellent-quality brew. The stainless steel mesh filter means you can also use it for hot beverage brewing. It also fits neatly into most refrigerator door bins whereas the Primula would require a gallon door bin.

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.
The County Line Kitchen mason jar brewer produced, at a best, a medium-strength bouquet. We detected a slight nuttiness as well as more subtle sweet notes. The results were not as good as we had hoped for, but promising nonetheless.
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.
We diluted the concentrate with one part coffee to one part filtered water. It had a dominant roasted flavor, but with a slight sweet aftertaste. The drink lacked nutty and fruity flavors that our top brewers were more successful at producing. Although smooth to drink, it lacked body and was not as satisfying as a cold brew can be.
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.
We brewed according to the County Line Kitchen manual’s instructions. This means we did not shake the vessel before putting it in the refrigerator. After allowing the brew to settle and then decanting, we were surprised to see a relatively significant amount of sediment.
The filter is a rough mesh rather than a laser-cut stainless steel filter as seen in other types of brewers. Although this brewer did better than average in producing a sweeter brew, we suggest additional decanting to remove excess sediment. Either that, or run the coffee through a paper filter.

The brew decanter is just as robust as any mason jar. The inner lid has a silicone gasket for a perfect seal. A handy notch lets you easily pluck the gasket out for cleaning. When sealed, even if you shake the jar around, no liquid spills and the flip cap stays secure too.
Stopper / Lid
- Diameter:4.9 in (125 mm)
- 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:6 in incl.handle (150 mm)
- Material:polypropylene plastic
- Additional Features:silicone gasket
The lid of the County Line consists of three parts. The handle is molded onto the crew-top lid. The handle is easy to grip with an inner thumb groove. To pour the liquid, you simply clip the flip-lid open which also detaches for easy cleaning. Inside the lid is also a gasket for airtight sealing. Although the handle is convenient, you can also opt for a simple screw top without a handle for a more compact option.
- Length:6.7 in (170 mm)
- 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.

Compared to other stainless steel filters we’ve examined, the County Line Kitchen’s looks and feels heavier. It matches the sturdy solidity of the mason jar and adds to its old-fashioned country feel. Although a fair bit of sediment is produced, our tests revealed that the brew produced is relatively good 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.
It’s difficult not to like the design of the County Line Kitchen cold brew coffee maker. If you like the solid practicality of a mason jar, it fits the bill. The part count is minimal and all components fit well. We also appreciate the option of buying a lid with or without a handle.

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.
Brewing follows six easy steps. Simply load the filter with coffee grounds — one cup per quart (reaching about one inch from the top) — and place the filter in the jar. Then, you slowly add water until the grounds are completely covered and the water level nears the top of the filter.
Allow to stand for a few minutes while the water makes its way through the grounds. Top up with water as needed, screw on the lid, and place in the fridge to brew. We found this process completely effortless with no need for weighing or measuring.
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.
We found the screwable cap may require a little force to remove depending on how tightly you put it on. The filter, though, is easy to grip and remove without any grounds dropping into the vessel. Like similar long-funnel filters, you can always place it in a cup to catch the last few drops. It’s best to rinse the lid of any grounds before replacing and putting the finished brew in your fridge. Because of the amount of sediment produced, we recommend recanting for a second time once the brew has been allowed to settle.
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.
For deep cleaning, you need to remove the flip cap and the lid’s inner gasket. The silicone ring seal for the filter simply slides off. The filter rinses out easily and you can use a gentle bottle brush if you wish. We found the small 1-quart jar a little narrow for hand cleaning, so we used a bottle brush there too.
All parts are dishwasher friendly, but it’s probably better to just rinse off the silicone filter seal and lid gasket. You’ll periodically need to soak the filter in a mixture of water and baking soda, vinegar, or citric acid to unclog coffee oils and remove odors.
After brewing, you will need a small space to store the filter. You should place it upside down so the silicone seal stays safe. When you are not using the jar, everything conveniently stores as a single unit.
