This past weekend I paid a visit to the Weinert bodega (vineyard + premises) in Lujan, an area south of the center of the city.
The winery is family-owned, and we were treated to an amazing Brazilian meal consisting of feijoala (sp?) and bobó do pesce (another spellcheck, please) courtesy of our chef friends and son of the winery owner. This was in preparation for next week's Brazilian Carnival expat luncheon to be held on the premises on Saturday.
We drank the 2005 Malbec (one of my favorites so far of the Malbecs I've had), the Merlot (didn't catch the year), the Cabernet Sauvignon, and then came my unlikely favorite (with dessert in the form of traditional Brazilian 'brigaderos'):
The Cosecha de Otoño Sauvignon Blanc
My new friend informed me that they sell in the US, and particularly in Texas, so keep an eye out.
