I love Marta’s Vinyard Malbec Reserve 2006 Lujan de Cuyo.
Came across it at a food and drink show and this was by far the nicest wine there and by no means the most expensive.
ABout £10 in the UK so I would guess around $15 in the US

Not sure where you can obtain it in the US, you could try contacting them through the website.
