Specs 2 (1)Just in time for Thanksgiving, Instacart, the popular food delivery service, announced Tuesday it has partnered with select liquor stores to offer alcohol deliveries in as little as an hour.

The San Francisco-based startup has partnered with Spec’s Wine, Spirits and Finer Foods to offer delivery of fine foods, wine, liquor and beer.

Right now, the service is available in Austin and Houston.

“Historically, Spec’s has been a destination shopping experience,” John Rydman, President at Spec’s Wine, Spirits and Finer Foods, said in a news statement. “But in today’s on-demand world, we need to offer same-day delivery so that our customers can enjoy the breadth of our alcohol and food selection whenever they want it.”

In Austin, the service competes in a crowded marketplace with Drizly, BrewDrop, Couch Potato Austin, TopShelf and Minibar all providing alcohol delivery via a mobile phone app to residences and businesses.

In San Antonio, Minibar just launched its alcohol delivery service last week. Although others have mentioned they are expanding into San Antonio, Minibar is the only one providing service right now.

For the Instacart delivery, customers must provide their date of birth at checkout to confirm they are 21 or older. they must also be present to sign for the delivery and to show proof of legal age with a valid photo ID.

“Spec’s initial delivery includes select zip codes of downtown Houston and South Austin with expansion in both cities coming in the following weeks,” according to a news release. It costs $3.99 for two-hour delivery on Instacart or $5.99 for one-hour delivery for orders over 435. The minimum order size is $10.
