Introduction:Want to explore the unique flavors of Panama Hartmann Estate’s wine-processed coffee through pour over? Based on actual brewing data, this article breaks down the estate background and processing features of this high-altitude bean, and details the V60 operation steps using 15g of coffee, a 1:15 coffee-to-water ratio, and 91°C water temperature—from blooming to the end of extraction—to help you master key techniques for bringing out citrus acidity, nutty aromas, and the layered complexity of wine fermentation. Ideal for coffee enthusiasts aiming to refine their pour over skills or explore specialty processing methods.
The reason pour over has become the go-to method for specialty coffee beginners is that it reveals the most delicate flavor nuances of coffee beans using simple tools and personal technique. Using Panama Hartmann Estate’s wine-processed coffee beans as an example, this article guides you step-by-step—from basic equipment selection to hands-on brewing parameters—on how to showcase this bean’s wine-fermented aroma, citrus acidity, and rich finish through pour over.
Pour over involves evenly pouring hot water over coffee grounds, using a filter paper and dripper to separate the grounds, typically taking three to four minutes to complete extraction. During this process, the flow rate, angle, and temperature of the water are all controlled by the brewer, so even with the same beans, different brewers may produce vastly different results. Especially for beginners, mastering equipment handling and parameter combinations is a key area that requires time and practice.
Let’s start with the basics: when choosing a pour over kettle, the spout design is paramount.A narrow-spout kettle allows for more precise water flow control,making it ideal for beginners to practice a stable pouring rhythm; drippers come in three main types—fan-shaped (slower flow, fuller body), cone-shaped (faster flow, brighter flavors), and wave-shaped (balanced flow)—with the V60 cone dripper being the most common choice; filter paper must match the dripper model, and unbleached natural filter paper may carry a subtle paper aroma, which you can choose based on personal preference; the grinder should be adjusted to a coarseness similar to No. 2 sugar (approximately medium-coarse grind), as the uniformity of each coffee particle directly affects extraction efficiency.
Hartmann Estate is a century-old coffee family in Panama. Since its establishment by Ladipo Hartmann in the 1940s, it has been passed down to the third generation. The estate sits at a high altitude of 1250–1700 meters and cultivates a variety of cultivars including Typica and Caturra, while also maintaining soil health by producing compost from fruit pulp and cherry skins. In terms of processing methods, in addition to traditional natural and honey processes, it has recently gained fame for its wine process—by mimicking the temperature and humidity control of wine fermentation, it imparts the coffee beans with richer aromatic layers.
The Hartmann Estate wine-processed beans used this time are a blend of Caturra and Typica, sourced from the Palo Verde block. Recommended brewing parameters: coffee dosage15g, coffee-to-water ratio1:15(total water volume 225g), water temperature91°C, paired with a V60 dripper and medium-coarse grind (such as BG#6S). The specific steps are as follows: First, perform a 30g bloom with water for about 30 seconds to allow the coffee grounds to fully expand and release aroma; after blooming, pour the second stage of about 95g of water (scale reading 125g) and wait for the water level to drop to half the height of the coffee bed; finally, when the coffee bed is about to be exposed, add the third stage of about 100g of water (total 225g) and let it drain completely. The total extraction time is best kept within1 minute and 50 seconds.
This coffee delivers highly layered flavors: upon opening, a distinct fermented wine aroma is immediately noticeable. The first sip brings bright acidity of citrus and kiwi, followed by the mellow notes of nuts and chocolate in the mid-palate, and a sweet finish reminiscent of brown sugar, accompanied by the delicate texture unique to wine fermentation. Ideal for those who enjoy a balance of fruity and sweet profiles, it’s especially recommended to savor each sip’s subtle changes with a cupping-level standard of attention.
