Inputs are imported too

Ted Diamantis, an importer of Greek wines who is based in Chicago, has been helping his suppliers stock up on bottles, labels and printing ink. The barrels, though, have him worried.

In two or three weeks, some of Greece’s winemaking regions will begin their annual grape harvest. The wineries Mr. Diamantis buys from age their wine in barrels from Italy and France, but Greece’s capital controls make it difficult for them to send money out of the country to pay for the barrels they need for this season. No barrels means no wine for Mr. Diamantis.

“Without the ability to access your capital, you can’t buy anything,” said Mr. Diamantis, who is in Greece meeting with his business partners. “The marketplace is frozen.”

That is from Stacy Cowley at the NYT.  Similar examples illustrate why Greece leaving the euro, even if a better idea for the longer term, would not have been such a picnic in the short run.  Exports would have collapsed, not boomed.
