Wine defects and faults
Good to hear from you. reefman, as home winemakers your subject to a lot of flaws in both our sanitation and the preparation in making the wine. For those of you who make fruit wines or are using fresh grapes. This becomes even more of a problem if the sanitation in the process is not handled properly. Even and especially racking and bulk aging, if the tools you're using are not up to the task which they were assigned to do then you have a problem, I'm going to try to address some of these problems. I myself and subject to some, but the more I do the wine and understated what my shortcomings are and I try to overcome those, so bear with me will go through some of the ones that hurt us the most.
A wine fault or defect is an unpleasant characteristic of a wine often resulting from poor wine making practices or storage conditions, and leading to wine spoilage. Many of the compounds that cause wine falls are already naturally present in wine but at least insufficient concentrations to adversely affect. In fact, depending on reception, these concentrations may impart positive characteristics to the wine. However, when the concentrations of these component greatly exceed the sensory, replace or obscure the flavors and aromas that the wine should be expressing. Ultimately the quality of the wine is reduced, making it less appealing and sometimes undrinkable.
Okay, let's take this for example I have a bucket of fresh juice. I bring it home and I know that it's at least a 45°, the yeast cannot start to activate at that temperature. So I let it set for a day or so and him him not paying too much attention to it, do a temperature reading and pitch my yeast. So far so good, right?
Check the specific gravity readings. Everything looks good time. The transfer from the ferment fermentation bucket to the carboy, so far so good. But I didn't have the time to sanitize the carboy. But hey, I'm in a hurry, yeah things to do so as a moving along. I pushed put this fresh batch of grape juice into a dirty carboy, not dirty as though you could see dirt and not sanitize didn't take the time to sanitize with one step or be bright, hey but that's okay I'm in the jar was empty. All they did was put the fresh juice into it. How wrong could that be? For my airlock in with water in and away go.
Every is going great. Up to this point, two weeks later I go back to the carboy. There is just right left it only know I see some white floaty things on the top and I wonder how this happened but that bong isn't sitting in the whole right it's like very loose, is that would cause the weight floaty things in the top or maybe it's because I've had about 6 inches of space or maybe more, but hey what's that got to do with it. I did put the airlock in it should are kept in the air out, shouldn't it?
There are many causes for the preparation in wine falls ranging from poor hygiene at a winery, excessive and or insufficient exposure of the wine oxygen, excessive or insufficient exposure of the wine to sulfur, overextended maceration of the wine either create or post fermentation, faulty finding, filtering and stabilization one, the use of dirty Oak barrels, or extend the barrel aging and the use of poor quality corks. Outside of the winery, other factors within the control of the retailer are and user of the wine can contribute to the reception of flaws in the wine. These include poor storage of the wine that expose it to excessive heat and temperature fluctuations as well as these of dirty stemware during wine tasting that can introduce materials aromas to what was previously a clean and full free wine.
So you see, I'm a mistake straight up,
and oxidation is a primary cause and the most common of all wine faults.
. Oxidation of wines. Perhaps most, common of wine faults, is the presence of oxygen and a catalyst are the only requirements for the process to occur. It is also known asmaderized wine. From Madeira wine, which is intentionally oxidized. Oxidation can occur throughout the wine making process, and even after the wine has been bottle. Which leads to loss of color, flavor and aroma, sometimes referred to as flattening. In most cases compounds such as sulfur dioxide and other acidic compounds are added to the wine by winemakers, which protect the wine from oxidation and also buying with some of the other oxidation products reduce their affect.
It's a little scientific doesn't, but it wasn't was my fault that I let the wine sit too long, I was busy and I did put the bong and the bubbler in the bottle it just was a bad fit, how was I supposed to know? Well, as a winemaker the truth is I'm supposed to have all my tools ready in my toolbox. I'm also supposed to have a plan and know when and how to implement that plan. If I had done these things had taken my time to plan my work and work my plan and had all my tools ready. I would not have asked gallons of fresh juice with white floaty things on top and airlock the doesn't fit and two weeks worth of oxygen after fermentation flattening my wine, what to do?
We do have reasons why things go wrong and sometimes we can find the answers, but most good winemakers know how to plan the work and work your plan. Oxygen, in the role of wine making is a double-edged sword to little and there's no fermentation, too much and the wine takes on a totally different characteristic.
Faults continued.
