We carry a diverse selection of Lavazza's whole bean coffees, and sometimes the bags are puffier than others, so we asked our importer to give us the lowdown on bean packaging.
It's fundamental to their freshness that they are packed in manner that will give them a long shelf life -- if they're allowed to oxidize, flavor compounds and aromatic properties will slowly degrade. To preserve freshness, Lavazza immediately packs their beans directly after roasting in high-barrier multilayer material that guarantees perfect vacuum packaging.
The roasting process, however, allows for the release of carbon dioxide and this represents 90% of the gas that forms inside of the package. To keep the bag from bursting, one-way valves are sealed into the package to allow the gas to escape without letting any air in. This one-way valve system guarantees vacuum packaging, even though the bag may sometimes be "puffy" and not compact.
