Description
A 5,000 L variable capacity tank earns its place when lot sizes don\’t line up with the tank farm. The floating lid rests on the wine surface and the inflatable gasket seals against the shell, so one vessel holds a full 5,000 L lot or a 2,500 L topping volume without headspace turning into an oxidation problem. We build these for cellars that press small blocks, keep variety lots separate, or need flexible storage through malolactic and barrel-alternative programs.
Construction details
Shell and lid are 304 stainless; we switch to 316L when wash water runs high in chloride or the cellar sits near the coast. Shell thickness starts at 2.0 mm with a 3.0 mm dished bottom, while the lid runs 1.5 mm so one person can lift and reposition it during a racking. Interior welds are TIG, ground, and passivated. Standard finish is 2B mill with an optional 320-grit polish on wine contact surfaces. The gasket is food-grade EPDM, inflated to roughly 0.2 bar from a foot pump or a regulated shop-air line — never straight off a compressor.

Questions we get before quoting
Will the lid seal at partial volume? Yes, down to roughly 40–50% fill; below that the gasket has too little wall contact to hold.
Do I need a cooling jacket? For storage in a cellar held at 15–18 °C, usually not. Add a jacket when you are running malolactic or cold stabilizing before bottling.
How is it cleaned? A CIP spray ball handles the shell with caustic and rinse cycles. Pull the gasket and wash it by hand — that is where wine residue hides.
Can it hold pressure? No. These are atmospheric vessels with a vent or airlock, not pressure-rated fermenters.
Tell us your batch size, wine type, number of tanks, and available floor space. We can recommend the tank volume, cooling area, and fitting layout for your cellar.

Although there were a few minor issues, thanks to Polly’s help, it looks brilliant and has brought my little distillery quite a few new customers.
Very good！！I see now in my texting to you that in my excitement over having the installation here in the USA I totally forgot to give you and the company of ACE a very big compliment on the quality of the whole Installation!! It all looks fabulous and the way you packed it in the container was extraordinary!! I am very impressed with your company and want to say a big thank you to everybody who worked on my order!!
We have been using this still for a few batches now making whiskey, gin and a few other spirits and we are very happy with the results so far. The gear works well and gives good control during distillation. The spirit comes out clean and consistent from batch to batch and we have gotten the flavor profile we were looking for. It has also been easy to operate and maintain. It has been a great addition to our distillery and I’d definitely recommend it to other craft distillers looking for reliable equipment.”
