Seña — Eduardo Chadwick & Robert Mondavi
A California–Chile partnership set out to change expectations. Follow Eduardo Chadwick and Robert Mondavi into Aconcagua, then let a dated blend explain the wine beyond the famous names.

Two wine worlds meet in Chile.
Seña traces its partnership to 1995, when Eduardo Chadwick and Robert Mondavi joined forces. The first vintage, also 1995, was released in 1997. Their ambition was to show the potential of Chilean fine wine, with Aconcagua as its growing place.
The producer’s account begins earlier, with Chadwick showing Robert and Margrit Mondavi around central Chile in 1991. Later, Tim Mondavi and Chadwick searched for the project’s own vineyard, seeking a cooler site. Robert’s California experience is the international founding connection here; he was not a Bordeaux winemaker.
Ocoa, within Aconcagua Valley.
Seña identifies its hillside vineyard with Ocoa in Aconcagua Valley →. Its account describes a setting influenced by the Pacific, with well-drained, rocky and gravelly soils and a mix of exposures. The question becomes how each part of that site contributes to the final wine.
Aconcagua is a valley extending from the Andean side toward the coast. It contains different growing situations. Seña is one estate within that landscape, not a synonym for the whole region. Compare its vineyard account with a second producer before assuming a single Aconcagua style.
A 2022 blend, clearly dated.
The official Seña 2022 sheet lists 60% Cabernet Sauvignon, 25% Malbec, 9% Carménère and 6% Petit Verdot. It is a Cabernet-led red blend from Aconcagua. Carménère supplies a recognisable Chilean connection within the project’s Bordeaux-inspired idea.
| Follow this clue | What it tells us |
|---|---|
| Grape composition · Seña 2022 | 60% Cabernet Sauvignon + 25% Malbec + 9% Carménère + 6% Petit Verdot. |
| Ageing · Seña 2022 | 18 months: 85% in French oak barrels and 15% in foudres. These percentages divide the ageing vessels, not the grapes. |

A foudre is a large wooden vessel. The sheet does not specify its capacity, so none is assigned here. Nor does “85% in French oak barrels” mean “85% new oak”: barrel share and the proportion of new wood are different measures.
Read the growing season beside the farming philosophy.
Seña describes its vineyard approach through biodynamic farming. Its 2022 report also discusses a dry season, water availability and irrigation decisions. Those physical conditions belong beside the producer’s philosophy when we ask how a vintage was grown.
A farming approach is not itself a tasting result. Read what the producer says was done, then distinguish it from what you notice in a glass. Weather, vineyard work, picking and cellar choices all deserve room in the account.
A partnership story reaches beyond one bottle.
Seña connects an established Chilean wine family with a Napa Valley pioneer. Follow Robert Mondavi → for the California story, then compare Almaviva → for a different international partnership in Maipo. Both can involve Bordeaux grape connections while remaining distinct Chilean projects.
The most useful comparison is concrete: identify the estate, locate the vineyard, date the wine and read its blend. Famous names can start the discovery; the growing place and the wine’s details let it continue.
A small Cork Dork discovery.
Let the maker’s account join your tasting.
Compare Seña 2022 with Almaviva 2022. List the grape proportions first, then the valley and ageing vessels. Notice Malbec’s role in Seña. If tasting, write your impressions before reading the producer’s description. Which differences can you document, and which remain your own observations?
