Introduction:When crafting a high-quality cappuccino, in addition to the extraction technique of the espresso, the choice of milk is equally crucial. This article presents a hands-on evaluation of Asahi Green Source's premium pure milk, analyzing its foam fineness, sweetness profile, and compatibility with coffee. We also delve into how it differs from common blended milks and offer practical advice to help café owners and coffee enthusiasts make more informed choices.
In the daily preparation of cappuccinos at cafés, many baristas focus heavily on the extraction of the espresso while often overlooking the key impact that milk itself has on the overall flavor. In fact, most cafés in China commonly use blended milks from brands such as Nestlé, Baxi, Mengniu, and Yili—products that often contain added ingredients and are diluted formulations. These not only have a weaker milk aroma but also a thinner mouthfeel, which can lead to a disconnect in flavors when paired with a rich espresso, making it difficult to achieve a harmonious taste.
In contrast, many World Barista Championship (WBC) competitors specifically select or custom-blend milk to achieve better cappuccino results. During our field research, we discovered that a particular brand’s “premium pure milk” is an unadjusted, pure milk with a shelf life of only about half a month. With its natural ingredients and rich milk aroma, it is particularly well-suited for specialty coffee preparation. For this test, we used this milk to evaluate its performance in cappuccinos across multiple dimensions.
The premium pure milk used in this test is the common 500ml retail size, with a production date of September 15, 2011, and a unit price of about 12.6 RMB—nearly double the price of typical blended milks. The packaging clearly states “unadjusted ingredients,” along with the production and expiration dates, emphasizing its “100% natural” positioning. Nutritionally, it contains approximately 5% protein and 6% fat, similar to common blended milks, but as an additive-free pure milk, these figures are considered quite good.
The coffee beans used in testing were provided by Qingdao Maison Roasting. It is an espresso blend primarily based on Colombian beans, also roasted on September 15, 2011. This blend combines beans from five different origins, featuring flavors of mild acidity, creamy aroma, and nuttiness, with a rich profile and a notable sweet aftertaste—making it highly compatible with milk for cappuccino preparation.
For espresso extraction, we used a Mazzer Major grinder and a Rancilio Epoca machine, setting the pump pressure to around 7.4 bar and water temperature to approximately 90°C. A low-temperature initial pour was employed to highlight the coffee’s layered characteristics. The grind was fine, with a tamping pressure of around 8 kg, total extraction time of about 21 seconds, and yield of about 22 ml. These parameters can be adjusted according to actual bean conditions and equipment—our goal is optimal flavor balance, not rigid adherence to fixed numbers.
For milk frothing, we used a MOTTA 350ml professional milk pitcher, heating the milk to about 65°C with an expansion rate controlled at around 40%. This resulted in a delicate, stable foam with good structure and a silky mouthfeel—a solid foundation for a successful cappuccino.
During the actual tasting, we first sampled the leftover milk in the pitcher and could clearly detect a rich milk aroma with foam as fine as cotton. It had a naturally sweet aftertaste, reminiscent of the flavor of glass-bottled fresh milk from childhood, earning high praise from our assistant. Next, we tasted the full cappuccino—where the aromas of milk and coffee blended harmoniously, resulting in a multi-dimensional yet well-balanced flavor, completely free of the fishy or watery issues often found in common blended milks. The mid-palate featured prominent nutty notes, with a clear sweetness in the finish. Overall, the performance far surpassed that of typical milk-and-coffee combinations found on the market.
Based on the comprehensive test results, if you are a café operator or coffee enthusiast pursuing extreme flavor, it is recommended to consider switching to premium pure milk. Although its price is higher—adding roughly 2 RMB per cup of 180ml coffee in terms of ingredient cost—the relative improvement in quality and customer experience is often a worthwhile investment. Especially in today’s competitive coffee market, flavor details are often the key differentiators for a brand.
It should be noted that currently, premium pure milk is mainly available in certain first- and second-tier cities such as Beijing, Shanghai, and Qingdao. In other regions, direct contact with the producer may be required for procurement. Additionally, due to its shelf life of only about 15 days, it is advisable to manage inventory reasonably based on sales to ensure freshness and further enhance the final flavor performance of the coffee.
