Fonseca Guimaraens
Port wine house (producer/company)
Fonseca Guimaraens, often simply called Fonseca, is one of the largest Port wine houses in Portugal. Manoel Pedro Gonçalves Guimaraens and his brother João Gonçalves Salgueiro, established the company in 1822 when they acquired control of the Fonseca and Monteiro Company from the Fonseca Family by purchase of the majority of Fonseca owned shares. A condition of the sale of Fonseca's shares was that the name Fonseca remain as the brand name. David Guimaraens, the great-great-great grandson of the founder Manuel Pedro, has been the head winemaker since 1994, and oversees the winemaking and blending for all four Taylor Fladgate Port houses: Taylor Fladgate, Fonseca Guimaraens, Croft, and Delaforce.
Fonseca maintains an estate, Quinta do Panascal, open to the public for tastings and tours. The vineyard Quinta do Panascal in the Douro has been classified as a Grade A producer of grapes. Fonseca currently ships a variety of Ports, including vintage, 10, 20 and 40-year traditional tawnies, a 10-year white tawny, late bottled vintage, non-classic vintages (Quinta do Panascal, Guimaraens Vintage), among others.
It is often confused with the similarly named, but completely unrelated, Portuguese wine producer José Maria da Fonseca, based in the Arrábida IPR on the Setúbal peninsula.
History

Why this record matters
The phrase “port wine house (producer/company)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q5465066. Authority coordinates are 41.160, -7.559. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1822 and 1994.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
