Description
The QHH cold brew maker is a 64 ounce glass jar with a handle, an airtight flip cap pour spout lid and a tall stainless steel mesh filter that hangs down inside it. It is listed at 18.99 dollars, weighs 2.44 pounds, measures 6.2 by 6.2 by 8.4 inches and has been on this listing since August 2023. A cleaning brush is included alongside the jar, lid and filter.
Cold brew is the least equipment dependent method in coffee. You put coarse grounds in cold water, leave it in the fridge for twelve to twenty four hours, and strain. The chemistry does the rest: without heat, far fewer of the acidic and bitter compounds dissolve, which is why cold brew tastes sweeter and softer than iced hot coffee and why it keeps for days. A dedicated vessel does not change the result, it changes the convenience, and that is the honest way to judge anything in the cold brew section.
The 160 Micron Filter
QHH gives a number where most competitors give an adjective: the mesh is 160 microns, made from food grade 304 stainless steel. That is a genuinely useful specification. A hundred and sixty microns is fine enough to hold back a coarse cold brew grind comfortably, and it sits in the range where you get clarity without the filter clogging.
It is not fine enough to produce a completely sediment free result. Cold brew concentrate from a metal mesh always carries some fines, and if you want it perfectly clear you filter it a second time through paper afterwards. What the mesh does well is the primary job of separating the bulk of the grounds from the liquid so that the brew can be stopped cleanly. The filter is also removable, and QHH points out that with it taken out the jar works as an ordinary pitcher, which is a fair secondary use for a large glass vessel.
Soda Lime Glass and the Warning You Should Read
The most important line on this listing is a caution rather than a feature. QHH states the jar is made from food grade soda lime glass and separately warns that the pitcher is not suitable for extreme temperature changes, so direct hot to cold transfers should be avoided.
Soda lime is ordinary glass. It is not borosilicate, and the difference is exactly the one the warning describes: soda lime has a much higher coefficient of thermal expansion and will crack under sudden temperature change. The practical consequences are specific. Do not pour boiling water in to make a hot bloom before adding cold water, a technique some cold brew recipes recommend. Do not take the jar straight from the fridge and rinse it under a hot tap. Do not use it for hot tea. The excerpt describing the glass as heavy duty is accurate about thickness and says nothing about thermal tolerance, and those are different properties. Brewers built from borosilicate, such as several in the pour over range, do not carry this limitation.
The Lid, the Seal and Fridge Storage
The lid does more work here than on most cold brew jars. It carries an ergonomic thickened handle, an airtight spout with a silicone sealing ring and a flip cap, so the jar functions as a dispenser as well as a brewing vessel. Being able to pour without removing the lid matters in a fridge, and a real seal matters more.
Cold brew concentrate keeps for around two weeks refrigerated, which is far longer than hot brewed coffee, and the limiting factor is usually oxidation and picking up fridge odours rather than spoilage. A silicone sealed lid addresses both. QHH’s phrasing about prolonging fridge beverage freshness is marketing language for a genuine property of a sealed vessel. The wide mouth also matters for the other end of the process: a 64 ounce jar you cannot get your hand into is a jar that never gets properly cleaned, and coffee oils build a film on glass that rinsing does not shift.
Capacity, Yield and Dose
Sixty four ounces is the jar volume, not the yield. The filter basket displaces some of it and the grounds displace more, so a full brew produces meaningfully less than 64 ounces of liquid. The listing does not state the yield, the recommended dose or the ratio, which is the single most useful thing a cold brew product could tell a first time buyer.
The conventional starting point is a ratio between one part coffee to four parts water for a strong concentrate you dilute, and one to eight for something you drink as is. On a 64 ounce jar that puts the coffee dose somewhere between roughly 170 and 340 grams depending on which you want, which is a large amount of coffee and worth knowing before you commit a bag to it. Coarse grind is essential, both to avoid clogging the mesh and because fine grounds over extract even in cold water.
Fields That Were Never Filled In Properly
Several specification entries on this page are placeholders rather than information. The manufacturer field reads cold brew pitcher, which is a product description standing where a company name should be, while the brand reads QHH. Model name reads cold brew coffee maker and item model number reads cold brew coffee maker, so the product has no model number at all.
Style reads 1pcs 64oz black, which is a packing description rather than a style. Human interface input reads Unknown, on a glass jar with no interface of any kind. Included components reads Filter Lid Glass jar and omits the cleaning brush that the manufacturer text promises. None of this affects a jar, but it is worth knowing that nothing in the specification block was checked, including the dimensions and the 2.44 pound weight.
What the Specifications Do Not Settle
There is no yield figure, no dose and no ratio, so the entire recipe is left to the owner. There is no filter height or capacity in grams, which determines how much coffee the basket actually holds and therefore how strong a full jar can be. There is no statement of the maximum safe temperature, only the warning against sudden change.
The listing says the pitcher can go in the dishwasher but does not say whether that applies to the lid and its silicone ring, which is where a dishwasher would do damage. There is no warranty. Nothing says whether replacement filters or lids are sold, and on a three part product losing the lid ends it. One bullet also lists breast milk among the suggested contents, which is an odd inclusion on a coffee listing and suggests the copy was assembled from a generic pitcher template. Buyers comparing this against the nearest alternative should note that the NFFTYUUT 64 ounce jar is listed at the same price with even less information.
Who It Suits and Who Should Look Elsewhere
This suits anyone who drinks iced coffee regularly and wants to stop paying for it. At nineteen dollars for a sealed 64 ounce vessel with a stated mesh size and a proper pouring lid, it is well specified for the money, and the 160 micron figure is more than most competitors disclose. The removable filter makes it useful as a pitcher out of season, and the dispenser lid is genuinely convenient in a fridge door.
It suits you poorly if you want to brew hot in the same vessel, which the soda lime glass forbids. It suits you poorly if you want a sediment free concentrate without a second filtration. And it suits you poorly if fridge space is tight, since a 6.2 inch square footprint at 8.4 inches tall needs a shelf to itself. Anyone who wants an immersion vessel that handles both hot and cold should look at a borosilicate press from the French press section, which does both jobs in one.
