原浆 means "original liquid" — and that is exactly what it is
The two characters break down simply: 原 (yuán) means original or primary; 浆 (jiāng) means liquid, pulp, or fluid. Together they describe beer in its most direct state — taken from the fermentation vessel before any significant processing has stripped or altered it. No filtration to pull out the yeast. No pasteurisation to kill whatever microbiological activity remains. What comes out of the tank goes into the package.
This was not a niche concept historically. It was simply the condition of all beer before industrial filtration became standard in the late 19th and early 20th centuries. The first lagers served at 19th-century Bavarian beer halls were turbid, yeast-laden, and perishable — not because brewers preferred it that way, but because the technology to do otherwise did not yet exist at scale. 原浆 is, in that sense, a return to origins rather than an innovation.
Today the term is used as a defined category in the Chinese market, governed broadly by GB/T standard language around unfiltered or minimally processed beer. The key technical markers are: live yeast remaining in suspension, absence of pasteurisation, turbidity visibly present in the finished pour, and a shelf life measured in weeks rather than months. Those four characteristics are what 原浆 producers should be delivering. Not all of them do.
How regular draft is made — and what gets removed in the process
Standard commercial lager follows a clear sequence after primary fermentation: cold conditioning (lagering) at near-freezing temperatures to drop proteins and yeast, then filtration through diatomaceous earth or membrane filters to produce a bright, haze-free liquid, then pasteurisation — either flash pasteurisation at around 72°C for 15–30 seconds, or tunnel pasteurisation in the can or bottle at around 60°C for a calculated number of pasteurisation units. The beer then goes into cans, bottles, or kegs. Shelf life at ambient temperature: six months to a year.
Each of those steps removes something. Filtration strips yeast, yeast-derived proteins, and some of the colloidal material that gives beer body and head retention. Pasteurisation kills microbiological activity, which is the point, but it also drives off volatile hop aromatics and triggers Maillard-adjacent reactions that push the flavour toward a cooked, cardboard-adjacent note at higher doses. The result is shelf-stable and consistent — you can ship it to the other side of the world — but it has moved meaningfully away from what the beer tasted like when it left the fermenter.
原浆 skips most or all of that sequence. After primary fermentation and a short conditioning period, the beer goes into packaging — sealed cans or bottles, typically under cold conditions — with the yeast still in it and no heat treatment applied. The trade-off is explicit: you get a more expressive, complex, perishable product in place of a stable, neutral one. Sell-through time matters enormously. A 原浆 beer that sits unrefrigerated on a retail shelf for three months is a failed product regardless of how good it was at packaging.
What 原浆 actually tastes like — and why it drinks differently
The most immediate difference is body. Yeast cells in suspension contribute genuine weight to the liquid — the beer feels fuller and rounder in the mouth than a filtered equivalent brewed from the same wort. Alongside the yeast, the proteins and polypeptides that filtration removes are still present, contributing to head retention and a creamy, sustained foam. Pour a fresh 原浆 and the head takes time to fall. That is not a presentation trick; it reflects the protein content.
Aroma is the second major difference. Hop volatile compounds — the esters, terpenes, and monoterpene alcohols that define floral, citrus, spicy, or herbal hop character — are heat-sensitive. Flash pasteurisation at 72°C drives a meaningful fraction of them off before the can is sealed. In an unpasteurised 原浆 beer, those compounds are still there. The pour smells demonstrably more alive: fresher grain, more hop presence, more of the fermentation esters that give craft beer its characteristic complexity. The difference is not subtle with a fresh product; it is immediately apparent to anyone who has drunk both side by side within the first few weeks of production.
The third difference is visual. 原浆 is hazy. Not cloudy from a manufacturing fault, not hazy from poor process control — hazy because the yeast and proteins are deliberately present. A slight golden turbidity in the glass is the correct result. If the beer in the glass is perfectly clear, the 原浆 claim is not reflecting the standard definition. Some producers use centrifuge clarification to a point where most gross yeast is removed but colloidal haze remains; that is a grey area. Genuine 原浆 by strict definition shows visible turbidity from live yeast cells.
Shelf life is where the trade-off lands. A well-produced 原浆 in a sealed, low-oxygen can might hold its character for 45–60 days under continuous refrigeration. Some premium producers target 30 days as their freshness window and are honest about it. The enemy is time plus warmth: yeast autolysis (yeast cells breaking down their own proteins) adds an unpleasant sulphurous note to aged 原浆, and oxidation develops faster in an unfiltered beer. Drink it fresh or the trade-off runs the wrong way.
How 原浆 gets into cans — and why oxygen management is everything
Packaging an unfiltered, unpasteurised beer in a sealed can is technically demanding in ways that filtered beer is not. The primary concern is TPO — Total Package Oxygen, the sum of dissolved oxygen in the liquid and the oxygen in the headspace at the moment of seaming. In a pasteurised lager, a slightly elevated TPO is undesirable but not catastrophic; the heat treatment has already committed significant flavour impact. In a 原浆 product, oxygen is the primary driver of premature ageing, and there is no pasteurisation backstop. Target TPO for a serious 原浆 product should be below 50 ppb at seaming, with world-class producers targeting under 30 ppb. That requires counter-pressure filling, inert gas purging of headspace, and disciplined dissolved oxygen control throughout the cold side.
Cold chain is the other half of the equation. From the moment the can is sealed to the moment the consumer opens it, the temperature must stay low — ideally at or below 4°C. Every degree above that accelerates yeast activity, speeds oxidation, and shortens the window during which the beer tastes as intended. This is why 原浆 distribution is, in practice, a logistics challenge as much as a brewing challenge. A brewery that produces excellent 原浆 but ships it through a warm-ambient distribution chain will deliver a mediocre product to the end consumer every time.
The easy-pull lid format that Cheerday uses for the Easy-Pull Pure Draft is a deliberate nod to the product's nature: a format that invites immediate consumption rather than long shelf storage. It signals to the handler and the consumer that this is not a warehouse beer. The 420 mL serve size is also sized around a prompt occasion — a single, fresh pour — rather than the bulk formats suited to ambient storage.
原浆 as a premium positioning in China's domestic craft beer market
China's beer market is large and structurally stratified. At the volume end, a small number of national brands compete on price in the mass lager segment. Above that sits a growing premium tier where consumers are willing to pay more and expect a discernible reason to — better ingredients, a traceable source, a defined brewing method. 原浆 has become one of the clearest category markers in that premium tier, precisely because its technical definition maps directly onto a sensory story: fresher, fuller, closer to the tank.
The category gained significant momentum from roughly 2015 onward as craft beer culture entered the Chinese mainstream, and has continued expanding through the 2020s. Notably, the growth is not only in craft-specialist channels. Mass-market Chinese brewers — including some of the largest domestic producers — have launched 原浆 sub-brands, which has created a definitional challenge: the term is now used across a spectrum from genuine unfiltered, unpasteurised beer to products where the processing has removed most of what the category claims to deliver. Buyers and importers should read the label carefully, ask for process documentation, and look at the turbidity in the glass.
For Cheerday, the Easy-Pull Pure Draft sits within a broader portfolio that includes classic lager and flavoured lines, but the 原浆 product carries the clearest craft-forward positioning. It is the product where the Qiandao Lake source water story, the unfiltered process, and the freshness-first packaging all converge. For wholesale and import buyers looking for a differentiated SKU that tells a coherent story — clean source, minimal processing, regional provenance — it is the natural anchor of the range.

Frequently asked questions about 原浆
Is 原浆 beer always unfiltered?
By the original definition, yes — 原浆 means the beer as it comes from the fermentation vessel, unfiltered and unpasteurised. In practice, some producers use the term loosely to describe beer that is lightly centrifuge-clarified but still carries natural yeast haze, or beer that is cold-filtered at 0.65 μm (removing gross yeast but retaining fine colloidal haze). True 原浆 beer by strict definition retains live yeast cells and shows characteristic turbidity. The consumer should see a natural haze in the glass — if the beer is perfectly clear, the 原浆 claim is probably not reflecting the original meaning.
Why does 原浆 beer taste different from regular canned lager?
Three main reasons. First, the retained yeast contributes autolytic breakdown products over time that add subtle bready complexity. Second, the absence of filtration means more protein remains in the beer, giving fuller mouthfeel and better head retention. Third, the absence of pasteurisation means the volatile aromatics from hops and fermentation are intact — the floral, spicy, fresh-grain notes that heat treatment drives off are still present in 原浆. The combined effect is a beer that tastes noticeably fresher, more complex, and more alive than its filtered equivalent.
Can 原浆 beer be exported?
With appropriate cold chain, yes. The constraint is not geography but temperature management and sell-through speed. Cheerday's Easy-Pull Pure Draft in cans is packaged with careful attention to TPO and cold chain, allowing a useful shelf window for export to markets with reliable refrigerated distribution. The beer must remain refrigerated from production to consumption. For markets where ambient-temperature retail is the norm, 原浆 export is not practical without reformulation to add pasteurisation.
The bottom line on 原浆
原浆 is not a marketing style — it is a processing specification with direct sensory consequences. Unfiltered, unpasteurised, cold-chain dependent. Fuller body, fresher aroma, shorter shelf life. For distributors and importers, it is a category that rewards honest handling and punishes logistical shortcuts. Cheerday's Easy-Pull Pure Draft is built around that logic: Qiandao Lake source water, 9°P wort, low-TPO canning, cold chain from tank to consumer.
