I'm hoping the other "two guys" in the "Three Guys Wine" venture won't be upset with me, but I had to make an executive decision. See, due to very reasonable but unforeseeable circumstances, we haven't been able to coordinate a good time for the first racking. And when it was looking like middle or end of March was going to be our first chance, I got worried that we were waiting too long. So this weekend, I bought a pump, and I did the first racking myself. Given the choice, we wouldn't have used a pump, but this was the only way I could pull this off on my own. I used very gentle pressure and had lots of patience waiting for the pump to move these volumes, so I don't think doing without would have been much more gentle.
Shown here is the 5-gallon carboy of Cabernet Sauvignon being racking into another carboy. Due to constraints of space and available vessels, this needed to be racked into a 6-gallon carboy, the original one cleaned, and then racked back into the 5-gallon carboy. One of the nice things about the pump was its large mesh pre-filter; meaning that I could suck up more liquid and the pre-filter would catch the sediment, leaving my racked wine relatively clear and wasting the least about of wine.
It's not all that easy to see clearly through a glass carboy, and taking a photo is even harder. But here is the leftover sediment after the first racking. The sediment is primarily made up of the "lees" or dead yeast from fermentation. But throughout the aging process, more solids will form and "fall out of solution" as the process continues. Based on the very little racking experience that I've had, the pump really helped get more of the wine out of the vessel. If you look closely to the right, you can see the wine on top of the sediment. That becomes waste, but when I racked a Chardonnay by manual siphon last year, I had a heck of a lot more waste.
One the 5-gallon batch of Cabernet was racked back onto it's carboy, there was about 1.5L of headroom that needed to be filled. This is essentially the difference in volume between the liquid and the solids, but also includes the wasted wine that can't easily be siphoned off. Generally, a wine maker keeps some extra must or varietal wines around to fill the headroom in any vessel like this. Or you can rack into smaller containers. Either way, some calculation and effort are needed. No problem here, I've got another 60L+ in the next steel tank, so I'll use that to top this one off.
Uh oh! Houston, we have a problem! Once I removed the "sealed" lid from the steel tank, it was obvious that this batch had gone bad. The air-filled rubber seals on these tanks are, shall we say, finicky. Getting them in place and sealed nicely is nothing short of a miracle and definitely more art than science. Never mind the fact that they are very difficult to clean and it only takes one grape skin getting moldy on the seal to cause all sorts of trouble in the tank. After pulling my hair a little, scratching my head, and contemplating next moves, I decided on the following course of action.
I looked through my wine making books and did a few Internet searches. Based on a few random and very unscientific observations, I guessed that this was mold and not a bacteria. Without getting into details and without being absolutely certain, this was based on there still being a reasonable alcohol level. I could be totally wrong, but I had limited time, drew a conclusion and acted on that information. I racked this wine off into a new vessel and left more waste wine to avoid carrying the surface mold into the fresh tank. Samples from below the surface showed no obvious signs of mold. This photo is the tank after the "usable" wine was racked.
Truth be told, this whole batch may be a complete loss. I did suck it up and taste the "clean" wine. It wasn't awful and I didn't keel over and die instantly, but I'm just not sure there is anything there to make an interesting drink from later. That said, there's no harm in keeping it to see if it can be saved. I blasted this batch with a decent potassium metabisulfite solution in the hopes of killing off the culprit.
This is getting long winded, but there was a lot that went on during this process. Next was the Cabernet Franc and I was SOOOOOOO happy to see nothing offensive on the surface when I removed the lid. In fact, after racking and tasting, I was very pleased with what we've got there. I'm sorry we only have about 100L of this, but we'll make the most of it. Seeing as how the tank aged C.S. may be dead, I instead used the Cabernet Franc to top off the first carboy of C.S.
Finally, I racked the Merlot, leaving about 40L of clean wine. Nothing terribly wrong with this batch, but hard to say if it will improve or not. Time will tell. We'll always have Franc.
