The Pato family has been producing wine at Quinta do Ribeirinho since at least the 18th century. João Pato started bottling wine from his vineyards in 1970, becoming the first producer/bottler in the Bairrada region after its demarcation.
His son Luis Pato inherited his non-conformist and pioneering spirit and in 1980 produced his first wine, a Baga monovarietal of exceptional quality and absolute rarity, which is today sought after by connoisseurs as a treasure.
In 1985 he starts two revolutions in Bairrada: he makes red wine from destemmed grapes and ages the wine in new French oak barrels. In 1988, he plants Baga on "pé franco" (ungrafted vines) to understand the pre-phylloxera wines and produces the first Old Vines in the country. In 1990 he takes part for the first time as a jury in the International Wine Challenge, a competition he assumes as a wine tasting school and a guide in the way to look and know the wines and the volatility of tastes all over the world. In 1995 he launches single vineyard wines: Vinha Pan, Vinha Barrosa and Quinta do Ribeirinho Pé Franco. In 1998 he buys Vinha Formal to produce his top-of-the-range single vineyard white wine. In 1999, by personal choice, it leaves the Denomination of Controlled Origin and its wines are labelled Regional Beiras. In 2001, it makes its first "precision harvest", harvesting the same vineyard at the end of August to produce sparkling wine and at the end of September to produce a more concentrated red wine. In 2005 he makes his first wine with his daughter Filipa, the FLP, using the cryo-extraction method. In 2008 he presents his first sparkling wine from a single vineyard, made from the Bical and Touriga Nacional varieties of the Formal Vineyard.
In 2009 he makes his first sweet natural wines (white, rosé and red), which he calls Abafado Molecular. In 2010 created the Informal and Quinta do Moinho, white sparkling wines from Baga harvested in the first harvest of a single vineyard: the Informal is from the Panasqueira vineyard and Quinta do Moinho is from the homonymous vineyard.
In 2011, Fernão Pires appears, the first red wine made from white grapes, with 94% Maria Gomes (Fernão Pires) and 6% Baga skin.
