From the Ithaca Journal comes this story about Winter CSAs, which are much more difficult to find than summer-month CSAs.
From the article:
Around Cincinnati, Turner Farm offers a winter CSA, but that's the only one I'm aware of. (If anyone knows of others, please speak up!)
A recent wintertime distribution had potatoes, kale, carrots, beets, parsnips, cabbage, leeks, rutabagas and salad mix.
Wintertime distributions generally contain less variety than summertime distributions because they include root vegetables that the farms have stored in humid cellars, in addition to freshly harvested produce. Kale grows outside unprotected in the winter because it can survive freezing temperatures, but other items, such as lettuce varieties, are grown inside a greenhouse in tunnels covered by poly-blend fabric.
