AeroPress Premium Walnut: the plunger coffee maker turns to glass and walnut
The AeroPress Premium Walnut pairs a hand-blown double-wall borosilicate glass chamber with anodised aluminium and solid walnut. It brews filter coffee, espresso-style coffee or cold brew.
What it is
The AeroPress Premium Walnut is a manual plunger coffee maker. The process is simple. You set the chamber on your cup, add ground coffee, pour in water, then push down the plunger. Air pressure forces the coffee through a paper filter, straight into the cup. The chamber holds 295 ml (10 oz), enough for one to two cups.
This model keeps the method that made the brand known, but changes its materials entirely. The chamber is hand-blown double-wall borosilicate glass, combined with anodised aluminium and solid walnut. The plunger is also solid walnut, fitted with a food-grade LFGB silicone seal. The filter cap, which holds the paper filter at the base of the chamber, is stainless steel.
The wood is American walnut, also known as black walnut, sealed with a food-safe finish. The box includes a scoop and a stirrer, both carved from the same solid walnut, plus a starter pack of paper filters.
This coffee maker suits anyone brewing one or two cups at a time and who likes to switch between styles. It can make filter coffee, espresso-style coffee and cold brew. There is only one version, in glass and walnut.
Why it exists
AeroPress makes manual plunger coffee makers, and all of them rely on the same idea: a “3-in-1” brewing method. It combines three stages. First, a quick immersion, where the ground coffee steeps briefly in water. Then micro-filtration, through the paper filter. Finally, air pressure, created by the plunger, which pushes the coffee into the cup.
What the brand promises with this method is a quicker cup, in under 2 minutes by its own account, with little bitterness and no sediment. AeroPress even states that brewing can take as little as 30 seconds. The brand also states that brewing and cleaning together take 2 minutes. In other words, the promise covers both taste and the time spent at the counter.
According to the brand, the original AeroPress was developed by Alan Adler in the early 2000s. The Premium Walnut is a descendant of that design. AeroPress unveiled it in September 2026 and presents it as the newest model in its Premium range. The brewing principle stays the same as the original. What changes is the finish: glass, metal and wood for both chamber and plunger.
What matters
A hand-blown glass chamber. The chamber is hand-blown double-wall borosilicate glass. Each piece may therefore show small imperfections in the glass. These are marks of the making process, not assembly faults. Borosilicate is the glass commonly found in vessels that hold hot water. The double wall places a layer of air between the coffee and your hand. According to AeroPress, this glass retains heat well, and the chamber stays cool to the touch.
Solid walnut, which needs a little care. Black walnut covers the chamber and forms the entire plunger. The sealing finish is food-safe. The brand recommends applying food-grade mineral oil to the wooden surfaces once a month. It’s a few minutes’ work, and part of living with this coffee maker, much like changing the filter.
A capacity built for one to two cups. With 295 ml, you get enough for one large cup or two small ones. For a full table, you’ll need several rounds. For morning coffee, alone or with someone else, a single plunge is enough.
A cup of the right size. The coffee maker sits directly on the cup. The cup’s inner opening needs to measure at least 6.5 cm (2.5 inches) and no more than 11 cm (4.25 inches) across. Before first use, it’s worth measuring your favourite cups. A mug that’s too narrow, or a bowl that’s too wide, won’t work.
A coffee maker with some heft. Glass, aluminium and solid walnut add up to real weight. The brand advises setting it down carefully on the cup. With a thin or light cup, it helps to hold it steady with one hand while pressing the plunger with the other.
Three brewing styles, standard filters. Filter coffee, espresso-style coffee, cold brew: the same device covers all three. It takes standard-size AeroPress filters, so restocking once the starter pack runs out is easy.
Day to day
On the counter, the coffee maker takes up 18 × 12 cm (7 1/8 × 4 9/16 inches). The chamber stands 17 cm tall (6.63 inches) and measures 12 cm (4.63 inches) across at the widest point of its hexagonal shape. The plunger, seal included, is 18.5 cm tall (7.25 inches) and 8 cm (3.13 inches) across. With the plunger pushed into the chamber, the whole unit stands 18.5 cm tall. That’s the position it stores most easily in a kitchen cupboard.
Cleaning is by hand only, never in the dishwasher. Keep it away from the microwave too. After each brew, remove the filter cap, discard the paper filter and grounds, then rinse the chamber and plunger. The walnut scoop and stirrer are cleaned the same way. Once a month, feed the wood with food-grade mineral oil.
The brand advises against taking it travelling. This is a coffee maker that stays in the kitchen.
All parts are free from BPA and PFAS. The plunger seal, the only silicone part, is food-grade LFGB.

What the brand says
AeroPress states that its coffee maker delivers a quicker cup, in under 2 minutes, with little bitterness and no sediment. According to the brand, brewing can take as little as 30 seconds, and preparation together with cleaning takes 2 minutes.
On the glass, AeroPress makes several claims: According to the brand, borosilicate offers excellent heat retention and resists thermal shock as well as scratches. The brand also states that the double-wall chamber stays cool to the touch.
AeroPress says all its products are checked by third-party laboratories, against US and European food safety standards.
The brand isn’t short on ambition either: it believes an AeroPress could make “the best cup of coffee” you’ve ever tasted.
Why it caught our eye
We were drawn to its pairing of hand-blown borosilicate glass and solid walnut, down to the scoop and stirrer carved from the same wood. We also like that AeroPress keeps its plunger method, moving from filter coffee to espresso-style or cold brew with the same device.
Exactly the kind of brand we’d love to come across on O!deal one day.
