Where to buy Maraschino liqueur?
We are the national importers of Luxardo Maraschino, and that is an absolute must in the Aviation (personally, one of my favorite cocktails).
DeanGold is right about Constantine being the distributor and you can have a liquor store order from them.
Also, there is a great retailer in DC called The Wine Specialist. I called there just now, and they are out of stock, but they can get it in next day. Their number is 202.833.0707.
In VA, we do sell the Maraschino, but it is not "listed" so stores have to special order from the state. The State has the Luxardo Maraschino in stock, so your local liquor store should be able to order it quickly.
