We want to get a sense of just how much variation there is in pricing and availability of spirits across the Washington region. Is a bottle of whiskey in Maryland or Virginia really more expensive than the same bottle in D.C.?

We’d like your help: We’re identifying two different 750 ml bottles of whiskey: Catoctin Creek Roundstone Rye and Jack Daniels No. 7 Black. The next time you’re at your local retail establishment, check out whether they have those two bottles and send us the posted prices.

You can use the Twitter hashtag #kojowhiskeyindex, email them to kojo@wamu.org or post the information in the comment section below.

On today’s show we’ve got Scott Harris of Catoctin Creek Distilling Co. and author Garrett Peck discussing the economic forces — seen and unseen — that impact the selection and price of liquor around our region.
