Le Cru
Disclaimer: Le Cru is pricey. It’s pricey because it’s a European-producer-based subscription service. To be specific, smaller European producers who don’t make the volume or perhaps have the resources to export to the States (making wine is expensive). A curated case of six bottles from say, Catalonia or Piedmont starts at $155, and shipping is free. If this sounds interesting, visit Le Cru’s excellent website, which has details on the various vintners it supports, along with approachable videos explaining the particulars of the regions it buys from.
