Depending on the brand, MillerCoors beers may be heat-pasteurized or cold-filtered and sterile-filled. Heat pasteurization involves slowly warming the beer to 140 degrees, then cooling it to room temperature to eliminate impurities. Our cold-filter and sterile-fill processes use cold storage and a series of filtration steps to prevent any potential compromises in beer flavor and quality.
We do our best to minimize packaging--for environmental reasons and to keep costs down for distributors, retailers and our customers. We've set ambitious goals for reducing packaging and waste associated with our products—and these goals get more ambitious every year. We offer a variety of packages and container sizes to accommodate the tastes of customers. Not all brands are available in all packages, and not every package is available in all areas. We color most of our bottles brown or green to protect the beer from light. For beers sold in clear glass bottles, we use patented light-stable hops that prevent beers from becoming "light-struck."
MillerCoors codes our cans, bottles, carriers and kegs with easy-to-read “sell by” dates. This helps you know our products are fresh. The codes can also indicate the date the beer was packaged, and the brewery, location, production line, and time it was brewed.
