A new wine app called Corkscrew collects wine lists from restaurants, makes them searchable and, whenever you choose a wine, garners enough information over time to predict which wines you might like on the next list you open.

At launch this week, the app allows users to navigate wine lists at more than 8,000 restaurants in over 50 cities.

The free iOS app doesn’t have every Los Angeles restaurant wine list in its sights yet, but it has enough to be useful. Fire up the app downtown and you get a list of nearby restaurants. That includes BadmaashLA Indian restaurant just down the block, Orsa & Winston, Bottega Louie and Drago Centro. No Bestia yet, but there are wine lists for L & E Oyster Bar, Elf Cafe, Mohawk Bend, Cliff’s Edge and Barbrix and many more — all organized by distance from where you are at the time. Further along, comes Little Dom, MessHall Kitchen, Patina, Drago Centro, République and Pizzeria Mozza.

Click on a restaurant and you see two tabs, one of “suggestions,” and one for “full list.” At Patina, the third suggestion is 1998 Chateau de Beaucastel Chateauneuf-du-Pape Homage a Jacques Perrin — at $1,185. This is a legendary wine, but not the most expensive of the suggestions, which are mostly in the three and four digits.
