His foundation was producing Penfolds famed red wine, Grange, which he oversaw from 1984 until his move to the USA in 1990. Daryl makes regular trips back to South Australia to oversee all winemaking operations for Groom to ensure the highest quality product.

Daryl’s passion for wine sees him judging and 6 international wine shows. Daryl has a guest on the NBC Today Show and has also been a repeat guest on E television in the USA.


Lisa started her career in the wine industry as a 17-year-old, working for Penfolds Wines in the Barossa Valley. During her 10 year tenure (which may have been longer, had she not married the winemaker), she involved herself in many facets of the company. She found a love for production control and its integration to sales and marketing. She was actively involved in creating the GROOM package. Lisa now manages the importation, sales, marketing and distribution of Groom Wines in the USA.

Lisa has an additional passion. She actively tends a one acre garden full of a huge variety of fresh produce. An additional one acre of fruit trees, along with eight chickens completes the picture. All organic, you name it, she grows it!

4th Generation Vigneron – Barossa Valley, South Australia
Barossa Valley Vintage Festival – Hand Grape-Picking Champion
Angaston Show – Most Successful Grape Exhibition

David has wine and grape juice, not only on his hands, but in his blood - a passion inherited from his grandfather, Ernst Mengler, a wine pioneer establishing his winery in 1899 at the foot of Mengler's Hill in the Barossa Valley. The building still stands today, although now converted to a private residence.

Outside of harvest, EB Marschall & Sons specialize in vineyard establishment, which they do across the state of South Australia.

David’s ultimate goal, of owning and growing his own grapes was realized by the Marschall Groom venture. Years of experience, training, and of course, the passion provides the foundation for a successful venture. In our vineyard, if vines had individual names, David would know them all personally!

Jeanette has many years of experience in payroll, real estate and office management. This grounding, along with a keen financial and business sense, has given her a wealth of knowledge in many areas, all of which has helped ensure stable financial practices for Marschall Groom Cellars as we move forward.

Jeanette’s spare time away from the financial side of the business is spent managing sales within the Australian market. Aside from all that, she spends time with her 6 kids and gets her hands dirty tending the vines. It is not uncommon to see the entire Marschall family, often along with Grandma and great-Grandma, planting, pruning, tying-on or even picking the grapes!
