A look inside a mobile wine bottling facility.
I’m one of those people who likes to see and do as many things as I possibly can. Life, to me, is a quest to learn and experience as much as possible. Each day I get to do or see or learn something interesting is another day worth living.
Yesterday was one of those days. I got an opportunity to photograph, video, and help out in a mobile wine bottling facility.
The Truck
Big wineries — like the ones everyone has heard of — have their own wine bottling facilities. These are likely big rooms filled with very expensive, highly specialized equipment. Big wineries can afford to buy and maintain these machines. After all, they’re producing thousands of cases of wine every year and may run the bottling line dozens of times a year.
Smaller wineries can’t afford such luxuries. Not only is the cost of the equipment usually beyond their means, but they also lack the space to house it and the funds to maintain it. Besides, they’re producing much smaller quantities of wine and only need to bottle once or twice a year. It just doesn’t make sense to make such a huge investment when there is another alternative.
That other alternative is a mobile bottling truck. This is a big rig truck with a trailer on the back. The trailer is completely outfitted with all the equipment needed to fill, cork, cap, and label bottles of wine.
The truck is driven and operated by a single technician who travels from one small winery to another. He knows exactly how to operate the equipment — which is both mechanical and computerized — and how to fix it if something goes wrong. He sets it up for the bottles, wine, corks, foil caps, and labels the winemaker provides. He then gets the line running while a handful of laborers the winemaker provides do the few manual tasks required to complete the process.
To say it was amazing is an understatement. Watching this thing in action was awesome.
The Bottling Process
Wine is pumped from a vat into the trailer.
This machine sterilizes the bottles and places them on the line in single file.
The bottles are filled with wine as they move.
Bottles move into the corking equipment where they are corked.
Two workers add foil caps to each bottle.
This machine presses the foil caps onto the bottle tops.
The bottles move past the labeler, which applies front and back labels with one pass.
This look from the front of the trailer’s inside shows the bottles on the right heading back toward the door.
Two people load the bottles into cases. They’re loaded neck down to keep the cork wet during storage.
Cases of wine slide down a track from the back of the trailer.
It all starts outside the trailer, where wine is pumped from its storage vat into the trailer itself though sterile hoses. From there, it goes into the filling equipment where it waits for the bottles.
Meanwhile, at the back end of the trailer, a forklift brings palettes of empty bottles to the open door. The bottom of each case of 12 bottles is unsealed. A man standing just inside the door takes a case, being careful to hold the bottom of the box closed, places it on a wide conveyor belt, and lifts the box, depositing the bottles, neck end up. He’ll do this four to six times a minute as long as the line is running.
The bottles then move, jiggling and clinking, into a rotating mechanism that sterilizes the bottles and places them on another belt where they enter the equipment in single file.
From there, the bottles are placed on tiny elevators that lift each bottle to a filling machine that moves the bottles along the line. The machine senses when the bottles are filled and stops adding wine.
The bottles then go into a corking machine that puts a cork into each bottle. Then the bottles move past two workers who place foil caps on top of each bottle. At the line’s speed, it would be nearly impossible for just one person to handle this task.
From there, the bottles move into a machine that pressed the foil caps down onto the top of the bottle, providing a secondary seal over the cork. Both the corks and the foil seals are customized with the winery’s logo.
Next, the bottles move past the labeler. The labels come on rolls that alternate front and back labels. The machine uses a vacuum to pull the labels off their backing, exposing the sticky side. As the bottles move past the vacuum pad, the sticky side of the label is pressed onto each bottle. The spacing of the labels is finely tuned for each bottle size.
At this point, the bottles of wine are complete. But they’re at the front of the trailer and need to be in the back. So they make the long trip all the way down the side of the trailer, in single file, to where two people wait. Stationed right beside the man who puts the empty bottles on the line, they have the empty boxes he discards in piles at their feet. The first person places a box on a workspace and fills it with six bottles as they file past. She then moves the box to her companion who places another six bottles in, closes the box, and pushes it through a machine that tapes it shut. Both workers are performing their tasks nonstop to keep up with the flow of incoming bottles.
After being taped shut, the box rolls down a ramp where other workers apply a label to the box and stamp the date on it. The boxes are then stacked on palettes. When all cases of a variety are bottled and stacked, the palette is wrapped with shrink wrap. It’s then transported into a temperature controlled storage area by forklift and an empty palette is prepared for the next variety.
The Results
At full speed, the equipment can process about 60 bottles per minute. The bottling tech told me we were running a little slower, maybe about 55 bottles per minute. That’s still pretty damn fast.
We bottled seven varieties of red wine yesterday, including one rosé. We used three different bottles, each of which required the machinery to be recalibrated for proper movement, corking, and label positioning. We started at about 8 AM and were finished by 2 PM. We took about an hour for a lunch break.
We bottled a total of 818 cases of wine.
Afterward, the six volunteers (including me) got to sample some of the wine that wound up in partially filled cases. Despite its bottle shock, it was pretty darn good. I think the Petit Verdot was the best of the bunch and really look forward to its release. And yes, I grabbed a bottle of that and a bottle of Zinfandel as my reward for a day’s work in the truck. I’ll wait until Pete officially releases them before I open them.
The Photos
I took a lot of photos during this process — the ones you see here are only a sampling that illustrate the main part of the process. The photos include shots taken on Sunday during the filtering, which I cover in a separate blog post.

The road climbed south slowly into the mountains on a narrow strip of park land. We found a parking area right before one of two tunnels and Mike parked the truck. There was a view to the northeast and we could clearly see the Juan De Fuca Strait, which runs between Washington and Canada’s Vancouver Island. It was relatively hazy and the conditions weren’t good for photography.
We were hungry and planned to dig into some of the cheese we’d brought along when we got to the observation point near the end of the road. But the road was closed for some kind of construction. So instead, we turned into the Altair Campground, which was mostly empty, and pulled into the first campsite, which was right along the river. We carried the cooler over to the picnic table, opened it up, and had a great meat, cheese, cracker, and cucumber lunch.
As we got closer and closer to the point, we could clearly hear the ocean waves crashing against rocks. There were a handful of short side trails to points where you could see the rocky shoreline. Some of them had been built up with rustic log rails to prevent a fall into the water below.
At the end of the trail was a platform that looked out to the northwest. There was an island out there with a lighthouse on it. To the north, was the opening of the strait and Vancouver Island; a container ship slowly made its way in toward the ports. Waves crashed on the shore against odd-looking formations called “stacks.”
