Hand grinding grind size for Blue Mountain coffee   How to store Jamaican Blue Mountain coffee beans for a long shelf life

Blue Mountain coffee is an extremely classic coffee.With such fame that even non-coffee drinkers have heard of it, Blue Mountain coffee remains a favorite among many coffee enthusiasts.Mandheling coffee is a representative of bitter coffee and also embodies the classic flavor of black coffee.Blue Mountain coffee is known for its balanced acidity, sweetness, and bitterness, but poor brewing techniques might lead to a disappointing cup.

This refers to coffee bean products only, not considering other products on the market such as freeze-dried, instant, or pod coffee, nor does it include grinding services.

,.When making Blue Mountain coffee, many factors need to be considered, among which grind size is an extremely critical element.Different brewing methods require different grind sizes.Here, we take the pour-over method as an example.Since Blue Mountain coffee is deeply roasted and grown at lower altitudes.Therefore, the beans are softer, and deep roasting causes Blue Mountain beans to carbonize more than typical high-altitude hard beans, making their internal structure more brittle and loose.Therefore, it requires a coarser grind.Coffee is generally made by grinding roasted coffee beans and then brewing them.

As mentioned earlier, coffee tastes better when freshly ground and brewed, and this is related to the nature of coffee itself.

The flavor compounds in coffee are released through the roasting process, which includes volatile and oxidizable flavor substances.And we can’t finish drinking coffee in one day, so typically 15g of coffee beans per serving is enough for a good brew.Therefore, it's also important to pay attention to the coffee beans’ shelf life and storage methods.

Of course, the shelf life of coffee beans is actually different from that of ordinary food.Coffee is all about the optimal flavor window, so the "age" of coffee beans does not refer to their production date but rather their roasting date.The optimal tasting period is after resting the beans for 4–7 days, and this period will last for some time, typically within 30 days post-roast.That’s why Qianjie Coffee recommends not stocking up on beans. It’s best to buy, grind, and brew them fresh. Storing them for up to 30 days is simple—just use the original professional packaging.
