Back-ups at shipping ports have caused a season of shortages for plenty of holiday must-haves like toys and food and now, the latest issue could be with alcohol.

Liquor store owners say they've been receiving fewer shipments of liquor, wine and beer.

New data shows 11% of alcoholic beverages have been sold out in stores nationwide since the end of November.

But the shortages don't stop at the drinks themselves. "There's a shortage in glass, there's a shortage in cork, there's a shortage in all materials necessary for bottling," says Aaron Warren, a liquor store owner.

Liquor store owners also say the shortage has forced them to raise prices by about $1 to $2 per bottle.
