I want to make a wine rack and the old field tile work real well.

I just found this link and am not sure if this will help you, Thanks.

Clay Roof Tiles: Field Tile (http://www.customtileroofing.com/Tiles_Field.asp)

If you are talking about roof tiles than yes, you can find them in just about every Roofing Supply house.

Now, I suspect you are talking about field drainage pipes. Usually, these people use for wine racks. Correct ? They are about 16" long and 5" in diameter... If so, than they are also available in masonry supply yards.

Milo nailed it with clay drainage tile.
If you can't locate any in your area click on: Clay Tile (http://www.sandkuhl.com/html/clay_tile.html)
Or if you're in the Sarasota area stop in to my house and I'll give you enough drainage tiles, (not used) to build a couple of wine racks. Good luck, Tom
