Andrea Robinson (think that's her name) who delta touts as their in house som, must be getting paid well because I would be ashamed at the quality of Delta's wine as a professional som. Domestic has become undrinkable in many cases. One would think Delta would have decent quality (quality does not mean expensive) wines flying across country, especially going to any of the Bay Area. Some good Napa or Sonoma wines. Guessing they choose their wines by the budget that are given and large quantity producers fit that bill.
I fly to Greece and Italy yearly. Just once would I like to have a decent Italian/Greek red wine on board when flying to these destinations in Delta One. Before anybody says it, there are high quality Greek reds out there and available in the US
