Poggio al Tesoro

Bolgheri estate founded by the Allegrini siblings in 2001, farming 64 hectares across four coastal plots to make Super Tuscan reds and Vermentino white within the Bolgheri DOC.

The producer

Marilisa Allegrini arrived in Bolgheri in 2001 with a specific ambition: to build a Tuscan coastal estate from empty land. She and her brother Walter had made their name in the Veneto with the family's Valpolicella and Amarone wines. Bolgheri was a different argument. International varieties on the Maremma coast, a DOC whose reputation had been written by Sassicaia. They bought 105 hectares, began planting in 2003, and Walter died that same year. Marilisa kept building. Her daughters Carlotta and Caterina joined the leadership over time, and the estate Walter helped conceive is now led entirely by women.

The range maps the Bolgheri DOC hierarchy directly. Il Seggio carries Bolgheri DOC status: a red blend aged 15 months in French oak with 30 per cent new barrels, giving earthy mineral aromas, blackberry, peppery graphite, and firm dry tannins. Sondraia carries Bolgheri Superiore status, named after Le Sondraie, the 50-hectare flagship plot. Aged 22 months in 70 per cent new French oak, it runs darker and denser: black cherry, currant, dark chocolate, savory spice, and a saline mineral quality on the finish. A Vermentino white completes the portfolio.

Notable facts

The story

The vines went in the year Walter died

Walter Allegrini helped choose the land in Bolgheri and was there when the estate was registered in 2001. Two years later, in 2003, the planting program he and Marilisa had designed was finally ready to begin. Walter died that year. Marilisa had a half-built estate, bare land waiting for vines, and no partner. She planted anyway. The four plots went in on schedule. Carlotta came into the business, then Caterina. The estate Walter co-founded in 2001, the one whose first vines went into the ground the year he died, is now run by three women: a mother and her two daughters. Every bottle of Sondraia carries his name in its vineyard source, Le Sondraie, the 50-hectare plot that became the flagship and the estate's largest piece of planted ground.

The Producer

Marilisa Allegrini arrived in Bolgheri in 2001 with a specific ambition: to build a Tuscan coastal estate from empty land. She and her brother Walter had made their name in the Veneto with the family's Valpolicella and Amarone wines. Bolgheri was a different argument entirely. The Maremma coast, not the northern hills. International varieties, not Corvina and Rondinella. A DOC whose reputation had been written by Sassicaia, not by the Allegrini family.

They bought 105 hectares in the Bolgheri commune and began a planting program in 2003, mapping the land across four distinct vineyard plots. Walter died that same year. Marilisa did not sell. She kept planting, kept building, and brought her daughters Carlotta and Caterina into the leadership over time. The estate Walter helped conceive is now led entirely by women.

The wines sit within the Bolgheri DOC hierarchy: Il Seggio carries Bolgheri DOC status, the entry tier; Sondraia carries Bolgheri Superiore status, the upper tier. A Vermentino white rounds out the range.

Place

Bolgheri is a Tuscan coastal DOC south of Livorno, in the zone called the Maremma. Its international reputation was built by Sassicaia, the estate that demonstrated Cabernet Sauvignon and Cabernet Franc could ripen fully on the Tyrrhenian coast and age as well as any wine in Italy. That success reshaped the DOC's permitted varieties and its ambitions. Today Bolgheri allows Cabernet Sauvignon, Cabernet Franc, Merlot, Syrah, and Vermentino, and its two label tiers, Bolgheri DOC and Bolgheri Superiore, separate wines primarily by minimum ageing and grape composition thresholds.

The climate is Mediterranean with a maritime edge. The Apennines to the east block cold continental air; the Tyrrhenian Sea to the west moderates summer heat and extends the growing season. Long sun hours push phenolic ripeness in the reds and keep natural acidity in the whites. The result on the label is fruit concentration paired with savory mineral character, a combination blind tasters consistently associate with the appellation.

Poggio al Tesoro's vineyards sit within this zone across four named plots: Via Bolgherese, Chiesina di San Giuseppe, Le Sondraie, and Valle di Cerbaia. Valle di Cerbaia falls within the Bibbona municipality just south of the Bolgheri commune boundary, adding parcel diversity to the estate's fruit sources.

Soil And Site

Le Sondraie is the estate's anchor plot at 50 hectares, the largest single piece of land Poggio al Tesoro farms and the source of the flagship Superiore's name. The planting program that began across these plots in 2003 has continued incrementally, with new plots added each year as the estate builds out its vineyard base.

The estate says long, sunny days contribute to its wines. The four plots span different orientations within the broader Bolgheri zone, giving the winemaking team a range of fruit sources to draw from when assembling the blends.

Story

The Allegrini family's move to Bolgheri was not an obvious one. Their name was built in Valpolicella, the Veneto appellation where the family estate produces Amarone, one of Italy's most internationally recognized red wine styles. Bolgheri required a different vocabulary. Amarone is made from partially dried indigenous grapes, Appassimento, intensity through dehydration. Bolgheri is made from Bordeaux varieties harvested at full ripeness in maritime heat, intensity through site and careful extraction.

Marilisa and Walter bought into the zone early enough that the infrastructure was theirs to design. The 2001 founding preceded the first vines by two years; the estate spent those years preparing the land before the planting program began in 2003. Walter's death the same year the first vines went in meant Marilisa took over the build-out alone. She completed the vineyard program and oversaw the range's development through the Bolgheri DOC hierarchy, establishing Il Seggio as the entry point and Sondraia as the estate statement.

By 2021 the estate had formalized its environmental commitments with the start of an Equalitas certification process, which audits sustainability across environmental, social, and economic dimensions. The bio-sustainability cultivation standards recognized by the Bolgheri DOC Consortium reflect the same direction.

Vineyards And Cellar

Poggio al Tesoro farms 64 hectares across its four plots. The planting is oriented toward international red varieties for the Bolgheri reds and Vermentino for the white, a direct reflection of the DOC's permitted range and the stylistic ambitions Marilisa set for the estate.

The two red wines differ most clearly in their time in wood. Il Seggio receives 15 months in French oak, with 30 per cent new barrels, giving the wine enough oak integration to support its fruit without dominating it. Sondraia receives 22 months in French oak, with 70 per cent new barrels, a significantly longer and more intensive élevage that shapes the Superiore's deeper tannin frame and darker fruit character. The gap between 30 per cent and 70 per cent new wood is not a subtle one; it marks a deliberate separation between two wines meant to occupy different positions in the range and on the table.

The estate manages waste through recycling and composting, part of the broader sustainability framework that includes the Equalitas certification process begun in 2021.

Wines

Poggio al Tesoro makes three wines: two Bolgheri reds and one Vermentino-based white.

Il Seggio carries Bolgheri DOC status, the entry tier in both the DOC hierarchy and the estate's own range. It is a red blend from international varieties, aged 15 months in French oak with 30 per cent new barrels. Blind tasting finds earthy, mineral, and peppery aromas alongside graphite, bergamot, and blackberry on the nose. The palate adds berries, stone fruit, and a note of peach tea. Tannins are described by Wine Enthusiast as big and solemn; the producer characterizes them as silky. Both observations are consistent with a young Bolgheri red from a maritime growing season: the tannins are present and framing, not soft.

Sondraia carries Bolgheri Superiore status, the upper DOC tier. Named after Le Sondraie, the 50-hectare flagship plot, it receives 22 months in French oak with 70 per cent new barrels. The sensory profile runs darker and denser than Il Seggio: pepper, savory spices, black cherries, currants, and dark chocolate on the nose; on the palate, berry fruit and chocolate with salinity and peppery heat providing the frame. The longer élevage and higher proportion of new wood push the tannins further and give the wine the density the Superiore designation implies.

The Vermentino white is confirmed in the range. No sensory detail is available in the current research.

In The Glass

Il Seggio opens with a nose that moves between the mineral and the dark-fruited: graphite and gun metal alongside bergamot, blackberry, and pepper. There is an earthy topsoil note underneath, the kind of character Bolgheri's coastal clay and warm summer days tend to produce in Cabernet-leaning blends. On the palate, the fruit registers lighter and brighter than the nose suggests, with berries and stone fruit and a faint peach-tea nuance in the mid-palate. The tannins are firm, dense, and dry at the finish, consistent with a young wine that has had its oak time but has not fully resolved.

Sondraia moves in a heavier register. The nose layers dark cherry and currant over savory spice and pepper, with a dark chocolate note that deepens as the wine opens. The palate carries that same dark-fruit and chocolate character, held in place by a saline mineral quality and peppery heat that runs through the finish. The 22-month élevage in predominantly new French oak gives the wine a density that needs time to settle, and the salinity suggests the coastal site is doing real work on the flavour profile.

A Bottle To Understand It

Start with Il Seggio. It is the Bolgheri DOC entry wine: shorter oak time, lower proportion of new wood, lower price, and more open in the glass than the Superiore. The nose gives you the appellation character cleanly, earthy mineral notes, blackberry, and that distinctive peppery graphite quality that shows up consistently in blind tastings of the zone. The palate adds stone fruit and the berry concentration you expect from long coastal sun. The tannins are dry and framing, which tells you what the wine is made of and where it comes from, without the additional weight the Sondraia adds through seven extra months in barrel and twice the new oak proportion. Il Seggio does not simplify the estate; it introduces it at the right scale.

Anecdote

Walter Allegrini helped choose the land in Bolgheri and was there when the estate was registered in 2001. Two years later, in 2003, the planting program he and Marilisa had designed was finally ready to begin. Walter died that year. Marilisa had a half-built estate, bare land waiting for vines, and no partner. She planted anyway. The four plots went in on schedule. Carlotta came into the business, then Caterina. The estate Walter co-founded in 2001, the one whose first vines went into the ground the year he died, is now run by three women: a mother and her two daughters. Every bottle of Sondraia carries his name in its vineyard source, Le Sondraie, the 50-hectare plot that became the flagship and the estate's largest piece of planted ground.

Final Word

Poggio al Tesoro is a Bolgheri estate built from scratch by a family that already knew how to make serious Italian wine elsewhere. Marilisa Allegrini brought the Veneto knowledge and left the Veneto varieties behind. The range maps the Bolgheri DOC hierarchy clearly: Il Seggio at entry level, Sondraia at the Superiore tier, each wine separated by élevage, oak proportion, and fruit intensity. The savory, mineral, dark-fruited character that blind tasters find consistently in the wines is the appellation doing its work on international varieties in long coastal sun.
