You can find half-wine barrels in a lot of hardware and gardening stores (at least in California) and use them to create a cute wine rack, and easily transport it inside or outdoors!
In California, you can find a half barrel as low as $15 and if you pay more than $25, you paid too much.

Step 1: Materials

Use safety glasses while operating the drill, jigsaw and hacksaw used to make the wine barrel wine holder. Use work gloves and latex type gloves where appropriate.
Materials needed:
1- Half wine barrel
2- Marker
3- Wood glue and all-purpose adhesive
4-A pair of pliers or a screwdriver whichever is needed to loosen the top ring of the wine barrel.
5- Jigsaw
6- Drill and large drill bit(approximately half inch)
7- Wood panels for construction of the top
8- Heavy Duty handles (2, one for each side)
9- Screws/nuts for assembling the handles. The size of the screws/nuts depends on the type of handles you choose to use.
10- Wine rack insert. You can use a ready-made one or construct your own. If you plan to construct your own, you need 10 feet of 4” diameter pipe and a hacksaw to cut it into 8" long pieces.

Step 2:

Choose a half barrel with its 2nd ring as close as possible to the bottom ring.

Step 3:

Wearing safety glasses, locate the nails or screws holding the 3rd ring and remove them. If you see something that looks like a big nail-head, but larger (circled in the picture), it is most likely the rivet holding the ring together. Do not remove it. Wear gloves to remove the nails or screws. The 3rd ring should slide down and be easily removed. You can make garden art using this ring!

Step 4:

Mark the slats that you want to remove. The section to be removed should be less than half of the circle. I would suggest removing 3 or 4 slats less than half of the circle.

Step 5:

On the 1st slat that you want to remove, and at the location just above the 2nd ring, drill a hole big enough for the blade of the jigsaw to pass through. Using the jigsaw, cut through the first slat (just above the ring) to be removed and stop at the last slat to be removed. As you pass through each slat, it will fall off.

Step 6:

Now it is time to make the tabletop. You can be as creative as you want choosing any type of wood or suitable material. I used left over Pergo laminate flooring panels. After snapping 3 panels together, I used a marker to trace the perimeter of the tabletop from underneath and then cut off the excess material using the jigsaw.

Step 7:

Using Gorilla Wood Glue (or general purpose adhesive) glue the tabletop to the top of the wine barrel. Make sure you use a pair of latex type gloves and wear a safety goggle while applying the Gorilla Wood Glue to keep your hands glue free and your eyes protected.

Step 8:

It is a good idea to attach two heavy duty handles for transportation. If you are doing this, make sure to drill holes through the wood and use both a screw and nut on both sides of the wood to secure the handles.

Step 9:

Now you can use a ready made wine rack as an insert.

Step 10:

If you want, you can make your own custom-made wine rack insert.

Use a 10 foot long pipe with a 4” diameter. You can use PVC (around $25) or do what I did. I used much less expensive pipe (about $7) that is used for leach lines. Using safety glasses and a hacksaw, cut the pipe into 8” long pieces and use 14 of them for the project. Use Gorilla All-Purpose Glue and glue the pieces together as shown here. Remember to wear latex type gloves to keep your hands glue free.

Place your insert inside the barrel. If the bottom row is too low, you can use one or two of the slats you removed to raise the wine rack insert.

Step 11:

If you like the rustic look, leave the wine barrel as is. If you prefer a more polished look, prime and paint your barrel, paint with several coats of wood varnish, or stain it.
