Ernst Loosen was born into a great tradition of German winemaking. Since the Dr. Loosen estate on the Mosel River has been in his family for over 200 years, you’d think it only natural for Ernst to take up the family legacy as a profession. The truth is, though, that as a youngster Ernst was more fascinated by the numerous Roman ruins in the area than by the family vineyards. So he went off to college to study archaeology.

In the mid-’80s, however, Ernst was faced with a decision. His father was ready to turn the estate over to the next generation and none of his brothers or sisters was old enough or interested enough to take it on. We could be melodramatic and say that it was time for Ernst to face his destiny, but really it was more of an odd-man-out decision. Happily, as it turns out, Ernst found his true calling among the broken slate of his family’s vineyards rather than the hewn stones of an old Roman ruin.

Ernst dove into winemaking with his customary fervor. He completed studies at Germany’s renowned winemaking school in Geisenheim and then launched into a selfdirected review of the great wines of the world. He traveled to Austria, to Burgundy and Alsace, even to California. He went wherever great wine was being made, seeking out the best winemakers to find out what they had in common. What he discovered was that they all share a dedication to producing intense, concentrated wines that boldly proclaim their heritage. They also have a worldly outlook that allows them to maintain respect for tradition while tempering it with reason. This gives them the freedom to acknowledge that not all traditions deserve to be doggedly observed, and allows judicious use of modern winemaking techniques when it will improve quality.

It is this global market view to which Ernst heartily ascribes. It is a philosophy that balances the old with the new. It is a way of thinking that has allowed him to move beyond the easy and familiar, the tried and not necessarily so true, to make wines that stand out as truly distinctive and world-class.

Bob Bertheau joined Chateau Ste. Michelle in June 2003 as its winemaker of white wines, after 16 years of winemaking in Sonoma County, California. He was promoted to Chateau Ste. Michelle head winemaker in August 2004.

“I am amazed at the difference in grape growing in eastern Washington,” says Bob. “We have such unique growing conditions here: low rainfall, extra sunshine during the growing season, cooler days at the end of harvest for longer hang time, and a pioneer spirit of the local growers and winemakers. These conditions help us grow world-class fruit and make wines of character, complexity and quality.”

Bob has maintained Chateau Ste. Michelle’s legacy of crafting awarding-winning Chardonnay, Riesling, Merlot and Cabernet Sauvignon, while putting his own signature on the wines. “My goal is to use winemaking to bring out the natural varietal character and the regional expression in the wines,” says Bob. “I have learned from Ernst Loosen, our German winemaking partner on Eroica Riesling, how to protect fruit purity and produce fresh, fruit-driven Rieslings.

"For Chardonnay,” Bob adds, “I’m using more Burgundian yeasts and have changed our lees stirring and oak regimes for better integration of oak flavors and more harmonious, soft Chardonnays. Washington’s red varieties have great structure and intense fruit. My goal with the reds is to harness the tannins for more accessible red wines from Chateau Ste. Michelle.” Prior to joining Chateau Ste. Michelle, Bob made his mark at Hambrecht Vineyards and Wineries with their Belvedere and Bradford Mountain labels. In his formative years out of UC Davis, he gained valuable mentoring from such renowned winemakers as Bob Sessions at Hanzell Vineyards and David Ramey at Chalk Hill. Wanting to gain an even broader experience with a wide variety of grapes and viticulture areas, Bob also worked at Gallo of Sonoma for five years, helping to bring a smaller winery mentality to the larger facility.

For Bob, the move to Chateau Ste. Michelle in 2003 was not only the chance to make wine for one of Washington’s most acclaimed wineries, it was also a chance to come home. He was born in Seattle, went to school in nearby Idaho, and has most of his family living in the Seattle area.

Bob has a degree in chemistry from Boise State University and an MS in food science and enology from University of California at Davis. Founded in 1934, Chateau Ste. Michelle pioneered vinifera grape growing in Washington state and has been producing classic European varietal wines under the Chateau Ste. Michelle label since 1967. The winery combines an ongoing dedication to research with a commitment to classic winemaking traditions.


Launched in 1999, Eroica is a labor of love for two of the world’s great Riesling producers. One from the Old World, Dr. Loosen estate of Germany, and the other from the New World, Chateau Ste. Michelle of Washington state. It’s an intermingling of Old World and New World philosophy and technique to craft an extraordinary Riesling from Washington state grapes. Named for Beethoven’s Third Symphony, Eroica reflects not only its variety and site, but also its heritage: bold and forward from its Washington roots, elegant and refined from German inspiration.

Chateau Ste. Michelle has championed Riesling for more than 40 years and was among the first to plant Riesling in Washington state. Ste. Michelle catapulted into the national spotlight when our 1972 Johannisberg Riesling won the now-famous Riesling blind tasting sponsored by the Los Angeles Times in 1974. Today, Chateau Ste. Michelle offers up to seven different Rieslings, each showcasing the versatility of Riesling and the regional styles within Washington’s Columbia Valley, which produces more Riesling than any other American wine region.

The Dr. Loosen Estate in the Mosel Valley has produced fine Riesling for over two centuries. During the last two decades, proprietor Ernst Loosen has traveled the world promoting the fine quality and long tradition of Riesling as a great wine in Europe, and now the New World. In 1999, Ernst Loosen approached Chateau Ste Michelle with the idea of joining forces after discovering the winery’s Cold Creek Riesling.

Estate Vineyards / AVA

There is perhaps no other grape variety in the world that captures the taste - the terroir - of where it's grown better than Riesling. And although Riesling is synonymous with the growing regions of Germany, Alsace and Austria, it finds an idyllic home in Washington state, where warm sunny days ripen the fruit while cool evenings preserve the crisp fruit acids essential for quality Riesling. Eroica represents a unique exploration of Washington Riesling.

The early Eroica blends were made predominately with Riesling from our Cold Creek Vineyard, a warm site producing a tropical, unctuous style of Riesling. Bob and Ernst’s quest for enhanced acidity and minerality eventually led them away from such a warm site to cooler climate vineyards in the Yakima Valley. Today, cooler vineyards that are consistent candidates for Erioca include Viewcrest in the Yakima Valley, Evergreen Vineyard, near the town of George, Washington, and our own Horse Heaven Vineyard in the Horse Heaven Hills AVA.

Beyond finding the best sites, Bob and Ernst also make sure the vines are being managed to produce the highest quality fruit possible. The team collaborates on site selection, irrigation management, crop levels and canopy management. They work with vineyard managers to adjust yields and manage fruit exposure to prolong the ripening season for added flavor development of these cooler climate vineyards. Over the past ten years we have changed not only where we are getting our Riesling fruit, but how these Riesling grapes are grown.

At the blending table, Ernst Loosen and Bob Bertheau considered dozens of small lots, each reflecting a slight difference in character, depending on the site. It is this blend of the finest Riesling fruit of the vintage that gives Eroica its remarkable complexity and character.
