Coffee roasters discuss a lot the sourcing, roasting curves, humidity levels and their new batch profiles. However, consistency, actual and reproducible consistency, often boils down to one much more mundane thing: the storage of the beans before and after roasting.
The majority of professionals use Ecotact Multilayered Hermetic Storage Bags because they eliminate the undesired variables that usually destroy a good deal. Having 9 layers that preserve food grains such as coffee, our bags are the most flexible ever in terms of food safety, high-barrier plastic packaging and storage options.
Roasters do not always publicise it, but behind the consistent flavour profile is a carefully managed storage operation. And with the growing specialty coffee market, the tolerance of inconsistency is getting smaller at an ever-increasing rate.
The Reason Inconsistency occurs More Frequently Than Roasters Admit
Green beans are delicate; they can easily get wet and go brown when the air touches them. When stored in normal bags, it is spoiled. Even the warehouse smells can penetrate through the packaging unless it is well sealed.
When a flavour goes wrong, most roasters refer to the roast curve, but the problem usually begins much earlier. Therefore, it all depends on storage, how it is performed, how stable it is, and how long it preserves the beans before they are loaded into the drum.
High Performance Storage Technology Levels the Playing Field
A skilled roaster will be able to fix slight variations, but not in the case of random variables in the materials. Due to this reason, hermetic multilayered solutions have become an industry standard swiftly. Their three advantages surpass all the rest and are as follows:
Non-slip Moisture Control
The majority of the storage bags breathe excessively. Even a slight change of 1-2 per cent in moisture will lead to the threat of moulding or loss of taste.
The solution to that problem is to seal with hermetic layers. Once it is sealed, the atmosphere will not change, and the beans will retain the desired percentage of moisture content. The roasters do not have to struggle with the loss of moisture or the surplus of humidity anymore.
Directly Affecting Flavour Oxygen Protection
The greatest enemy of consistency is oxygen. An excessive amount of beans will be tasteless before they are roasted. Excessively low, and the danger of becoming fermentation-like.
Higher technology of multilayer assists roasters to maintain oxygen levels at predictable levels, thus not being caught up by dull aromas or unexpected brightness in the cup.
Increase in Freshness of Green Beans
The majority of roasters require flexibility. You may roast a certain origin every week or once every two months. Storage technology will provide the breathing space.
Beans maintain their nature over a more extended period, enabling the roasters to plan their schedules, create blends, and maintain cafes in stock without further notice.
The Reason why Brands such as Ecotact are Exceptional
Ecotact is designed to address the daily problems of roasters. Their long-lasting stability, multilayer packaging, and sterile sealing help preserve flavour, even in cases of long-travel distance or prolonged storage of green beans.
Roasters depend on Ecotact, not only to get good packaging, but to get the same, predictable outcome. And consistency is what counts in speciality roasting.
To answer the question about the importance of good storage, studies have shown that the water activity and oxygen exposure directly affect the shelf life of green beans. It validates the perspective of roasters in their day-to-day existence: micro environmental shifts alter the end cup.
The Final Stage: Safeguarding Roasted Coffee Too
Roasters usually concentrate on the green beans storage; however, roasted coffee requires protection as well, particularly during shipping or prior to final packaging.
Hermetic Vacuum Packaging Bags comes in at this point. Vacuum sealing assists in trapping aroma, oxidising slowly and inhibiting contamination. In the case of roasters who sell coffee to cafes or retail clients, it guarantees that the coffee has been delivered in the same state that it was at the roastery, fresh and full of flavour.
