Winemakers/Cellar Rats: Is there a way to create one mixing tank by using multiple smaller tanks?

Moved into my own space now, but it's a very small facility and space is a premium, so have a question for the professionals. Problem: I need to have a blending tank for bottling and homogenizing purposes. Probably around 1100-1200gal capacity. But then I found these square and stackable Stainless IBC tanks (see link), that would really help me maximize my space. But the biggest one is on only 550gal. So let's say I have two or thee of those - is there a clever way of pumping across, transferring and continually blending until you have a completely homogenized lot? Feels like almost a math problem - and I sucked at math.

I don't mind if it's a little more labour intensive, as it only happens a few times a year, but it does need to blend the wine fully.

PS. When I think of this problem I keep recalling that scene in Die Hard 3 when they need to get 3gal into a jug to disarm the bomb, but they only have a 5gal or something.

There's always a way! You just need a tape measure, and a remote for your pump with a long enough cord so you can be at the top of each of your tanks with the tape measure and stop the pump when you get to the correct measurement. Or, you need to have two people: one with the tape measure on top of the tanks, and one standing by the pump. If you don't use pumps, there's still a way to do this with smaller tanks, but it always involves a tape measure. Flashlights are very helpful, as well as the calculator on your phone. You could also make 3 completely different blends, in each of the 3 smaller tanks, but put the same label on the 3 blends. I'm sure it happens!

Would what you're looking to do work by blending the wine at bottling? You could use a hose connector fitting that will hook up hoses from each of your 2 or three tanks into a single hose that will then go through a pump and to the bottling line. As long as the volumes in each tank are equal, the wine should blend in the hose. Not as effective and precise a method as what Ed suggested, though.

OK, thanks.

Bare with me for this mathematical exercise and question:

1. In tank A I put the contents of barrel 1 and 2.
2. In tank B I put the contents of barrel 3 and 4.
3. Into a separate tank C, I transfer half of tank A and half of tank B to mix. Tank C is now full and has an equal amount of liquid from all barrels, right?
4. Now tank A is half full and I can transfer tank B into tank A to make that full and leave tank B completely empty. Now tank A has an equal amount of liquid from each barrel.

So far so good. Now that tank C and tank A are full, but are they really identical, tho? Or do I need to mix this even more?

This is my question to the brain trust.

Sounds like that would work. Since you still would have an empty tank, I suppose you could always repeat the process once more but I don’t know that it would be necessary.

Your approach is what I do with much smaller quantities in carboys but it’s the same theory. Works just fine and no need to do more than once.

I think you split the line with a T or Y during both movements -- both when you rack into tanks and, as Ken suggested, when you come out of tanks to bottle. If you rack separate barrels to the separate tanks, you have to move the wine more in circulating between tanks or racking an extra time. Even if you want to add in one of those extra steps, you're further along in mixing by splitting the line during racking.

Brian, Stewart - thanks.

Makes sense to have a T or Y split from the barrels, so they're already going half in each.

Cheers.

Note that you can also get those tanks with glycol - something to consider in the case you want to use one for cold stability or controlling temperatures in the future.

Cheers.
