Description
The NFFTYUUT cold brew maker is a 64 ounce glass jar with a handle, a lid and a stainless steel filter, listed at 18.99 dollars and available since April 2023. Beyond that sentence there is almost nothing. This listing has no manufacturer description at all, no feature bullets, and a specification block in which several of the numbers cannot be true at the same time. Reviewing it honestly means saying what is known, what is claimed and what simply is not there.
What the product does is not in doubt, because cold brew is the least equipment dependent method there is. Coarse ground coffee sits in cold water for twelve to twenty four hours, then you lift out the grounds. Without heat, far fewer acidic and bitter compounds dissolve, which is why cold brew tastes sweeter and softer than iced hot coffee and why it keeps for a fortnight in a fridge. A vessel like this changes the convenience, not the chemistry, and every other product in the cold brew section is doing the same job.
What the Title Actually Promises
With no description on the page, the product title carries the entire specification. It states a mason jar style iced coffee maker in durable glass, 64 ounces, described three ways as 64 oz, 2 quart and 1.9 litre, with a handle and a stainless steel filter, suggested for iced coffee, lemonade, iced tea and homemade fruit drinks.
Those three volume figures are consistent with each other, which is more than can be said for the rest of the page. Two quarts is 64 fluid ounces and 1.9 litres is the metric equivalent, so the capacity claim at least agrees with itself. Everything else on the listing has to be read as an assertion rather than a specification, because there is no supporting text anywhere.
A Capacity Figure That Contradicts the Dimensions
The specification block gives product dimensions as 3.4 by 3.4 by 10 inches. A vessel with a 3.4 inch footprint standing 10 inches tall encloses roughly 90 cubic inches at its absolute maximum, treating it as a perfect box. Ninety cubic inches is about 50 fluid ounces, and a real jar with a curved shoulder, a neck and a lid holds considerably less than its bounding box.
The stated 64 ounce capacity cannot fit inside the stated dimensions. One of the two is wrong. The most likely explanation is that the dimensions describe something other than the assembled jar, perhaps the filter alone, since a 3.4 inch diameter tube 10 inches long is exactly the shape of a hanging cold brew filter basket. The nearest comparable product in this catalogue, the QHH 64 ounce cold brew jar, gives its dimensions as 6.2 by 6.2 by 8.4 inches for the same claimed volume, which is a plausible shape for 64 ounces and a good indication of what this jar probably measures.
Capacity Given in Pounds
The capacity field on this listing reads 4 Pounds. Capacity is a volume and pounds are a mass, so the entry is meaningless as written. It is not a rounding error or an ambiguous unit; the field simply contains the wrong kind of quantity.
Four pounds is roughly 64 fluid ounces of water by weight, which suggests someone converted the volume into the weight of its contents and entered that. If so, the reasoning at least traces back to the right number, but the field as published tells a buyer nothing and would mislead anyone reading quickly. Item weight is separately given twice, as 1.11 kilograms and as 2.44 pounds, which are the same figure expressed in two units and are at least consistent with each other and with the QHH jar of similar size.
The Filter, and What Is Not Said About It
A stainless steel filter is named in the title and in the excerpt on this page, and nothing further is stated about it. There is no mesh size in microns, no steel grade, no length, no capacity in grams and no confirmation of whether it hangs from the lid or sits in the neck.
Mesh size is the specification that determines everything about how a cold brew filter performs. Too coarse and grounds pass into the concentrate; too fine and it clogs and drains slowly. Competitors at this price do publish the figure, and the QHH jar states 160 microns and 304 grade steel. The absence here is not proof of a worse filter, but it does mean a buyer has no way to compare the two on the one specification that matters, and it is the clearest example on this page of information that exists and was simply not entered.
The Glass Type, Which Determines What You Can Do With It
The material field reads Glass and nothing else. That single word conceals the most consequential question about a cold brew vessel, because ordinary soda lime glass and borosilicate glass behave completely differently under temperature change.
Soda lime is the cheaper option and it will crack if you pour hot water into a cold jar or rinse a cold jar under a hot tap. Borosilicate tolerates both. Several cold brew recipes call for a hot bloom before adding cold water, and plenty of owners rinse a jar straight from the fridge without thinking. If this is soda lime, both will eventually break it, and there is no warning on this listing because there is no manufacturer text at all. The safe assumption at this price is soda lime, and the safe habit is to treat it as cold only until proven otherwise. Anyone who wants a vessel that handles boiling water should choose one that states borosilicate explicitly, as the brewers in the pour over range do.
What the Specifications Do Not Settle
Almost everything. There is no yield, no recommended dose and no ratio, so the recipe is entirely the owner’s problem. The conventional starting point is one part coffee to four parts water for a concentrate you dilute, or one to eight to drink as is, which on 64 ounces means a substantial amount of coffee, and coarse grind is essential to avoid clogging any mesh.
There is no lid description beyond the field With Lid reading Yes, so whether it seals, pours or simply sits on top is unknown. There is no statement of dishwasher safety. There is no warranty, no included components list and no confirmation that the cleaning brush most competitors include is present. Style reads Tableware, model name reads 1 and item model number reads 1, so the product has no identifier. Country of origin is China. Special feature reads Manual, which on a jar is a statement of the obvious.
Who It Suits and Who Should Look Elsewhere
This suits someone who wants a large cold brew jar for under twenty dollars, is buying on price alone, and treats the listing as a rough indication rather than a specification. Cold brew is forgiving enough that almost any sealed vessel with a strainer works, and the method matters far more than the container. If it arrives as described it will do the job. The Takeya 10311 cold brew maker is the plastic bodied alternative at a similar size.
It suits you poorly if you want to know what you are buying. The capacity contradicts the dimensions, the capacity field is stated in pounds, the filter is undocumented and the glass type is unstated, which between them cover every question worth asking about a product of this kind. At the same 18.99 dollars the QHH jar publishes its mesh size, its glass type and a hot liquid warning, which makes it the better informed purchase rather than necessarily the better jar. Anyone who wants cold brew from equipment they already own can also simply use a French press, which steeps and strains in one vessel and needs nothing else. The Bodum Brazil press is a straightforward vessel for that.
