I’m much less experienced than most people on here, but in addition to the ones you named, I really love Alamaviva (and to a lesser extent Almaviva’s 2nd wine “Epu,” although, that’s very hard to find outside of South America) and Clos Apalta Petit Clos (Clos Apalta’s 2nd wine, which is think is a great wine and great value).
I have been happy with most of those listed above but have been repeatedly let down by Don Melchor. Another one to seek is a unique local grape blend under the label BoRoBo.
Prices there will be much higher than here IIRC since they subsidize the export market price a bit. If this is still true, the Lapostolle wine quality is very good across all price points.
To name a few:
Errazuriz Max Reserva Cabernet Sauvignon
Montes Folly Syrah
Vik 2015 Milla Cala Millahue Red
Neyen Espíritu de Apalta Carmenère-Cabernet Sauvignon
Concha y Toro Don Melchor Puente Alto Vineyard Cabernet Sauvignon
Santa Rita Casa Real Estate Bottled Cabernet Sauvignon
Bodega Volcanes de Chile Tectonia Red
Santa Carolina Herencia Carmenère
Oh, I just noticed that you’ll be in Santiago. I highly recommend you eat at Borago if you like out-of-the-box fine dining. 99 Restaurante is also great. I’d bring back more Almaviva Epu if I went again, since I can’t find it in the States, but a lot of the other wines that they actually export are less expensive in the states (from what I saw).
I’ve been really into Pipeños, I reccomend Aupa from Viña Maitia. Also A los Viñateros Bravos make great Cinsault from Itata, as well as Pedro Parra’s Pencopolitano.
Von Siebenthal has a great lineup, I like his Petit Verdot called Toknar. Tabali makes a great Pinot Noir called Talinay, and Errazuriz Las Pizzaras Chard is great.
Borago is quite the experience and is worth going to over 99. If you have time, 99 is worth going to for lunch (that’s what we did, since we also had scheduling problems). It was a casual, yet wonderful and sophisticated 3 or so course lunch. However, on Sunday, be prepared for 99% of restaurants to be closed. It’s kind of mind boggling.
Borago is awesome and had some excellent wines on my visit there (I do recommend the pairing option), including a stellar oxidative riesling hand bottled for the restaurant from Sierras de BellaVista. I dig natty unusual wines and loved Bodegas Re’s Pinot Noir velado - another oxidative style wine, more rose than traditional pinot, and 2012 was the current vintage release as of earlier this year.
Not wine - but I really dig Fuente Las Cabras for casual meals with good Pisco sours, a modern spin on old school Santiago diners. They might be open on Sunday afternoons. Baco was my Sunday go-to restaurant. Get the machas meunière! A table next to mine one night was drinking a 69 (I think) Dom they brought and offered a sip! The wine list is just OK, again the Pisco sours are very nice : )
Is Don Melchor too expensive these days for what it is or out of vogue? I remember picking it up at Costco for $50 something but those days are probably gone.
Almaviva is the best I’ve tried out of Chile but the Purple Angel is nice too.
Nothing really mind blowing out of the region IMO.
