How to clear and fine your wine with chitosan and kieselsol
What is clearing or fining wine?
Wine, both red and white, contain tiny particles that suspend themselves in the wine after fermentation. Most people agree that this is unsightly and completely not an option for quality wines. I agree with them. Clearing, or fining wine, is the process of gathering these tiny suspended particles and making them fall to the bottom of your container to be easily removed or left behind with racking. Despite what many first time wine makers think, this process is very simple and requires little to no experience with wine.

Different types of fining agents.
When asking how to fine your wines, many people are often given very difficult or complicated methods to fine their wines. Egg whites is the most common answer given to new wine makers asking for tips from older wine makers. Times and technology have changed and given us better and easier methods to fine wine. I personally do not recommend using egg whites. This can be messy and not the most sanitary method available. This can also often leave unpleasant tastes in your wine that some people can pick out.
Another method of fining your wine is by using a filtration system made for wines. This again, I do not recommend solely for the fact that if you do not get most of the suspended matter out before you filter, your filter pads will become clogged and not do their job properly. This can become a concern. However, after you remove the bulk of the suspended particles in the wine, filtering becomes a very good idea, especially in kit wines. I don't really recommend filtering wines made from fresh crushed grapes or fresh juice because they have a much higher aging potential and filtering could remove some of the good stuff for aging. This really depends on the type of wine being made and the quality of the grapes or juices. Just a quick thought.
Bulk aging is another very good method of fining a wine. If a wine is left undisturbed the fine particles will slowly but surely fall out of suspension to the bottom of the aging container. If you can wait long enough and have enough patience, you will surely have a great cleared wine. There are some things that are required for the bulk aging method to work. First, the wine clears best if the wine is degassed. If you have an oak barrel, the wine will degas efficiently and the particles will drop. This will require racking the wine also every couple of months to a new barrel or carboy while you clean your aging barrel. If you use a carboy for aging, you will need to degas using a method like the vacuum pump method (will discuss this in a future article). Again, racking is necessary if using a barrel or carboy. Letting a wine clear itself like this makes the best quality wine possible as there is no additive to leave an off-taste or flavor. 100% wine.
However, there are sometimes that a wine just refuses to clear. To clear a stubborn wine you need to add an additive that has the opposite charge to the suspended particles. Introducing Chitosan and Kieselsol.
Chitosan and Kieselsol are my golden clearing agents that I personally use to clear a stubborn wine. I find that this is the best method for clearing a wine that will not clear with time. I have used this many times on many different wines and have never been disappointed. Within 3 days time you will have a crystal clear white wine or a pristine red wine. You can pick this stuff up at almost any wine making store and it comes with simple instructions on how to use it. I recommend this 100%. Use this before filtering if you can also.
I have listed some of the most popular methods of fining or clearing a wine. By no means is this the complete list. I could go on for days about different methods people have used over the centuries, but I will not oblige you with this. That is a story for a different day. I have however, listed some of the easiest methods available that yield promising results. Like stated above, I really recommend you use chitosan and kieselsol as your first choice past bulk aging if your wine will not clear. I cannot stress this enough. It really does work wonders. Also, use the chitosan and kieselsol about a week before you bottle. This gives the wine enough time to drop particles while you are bulk aging and the particles can naturally give the wine better flavors while aging.
In order for bulk aging to properly clear your wine, it is recommended that you give your wine proper time to be able to clear. This time frame includes approximately 12 months with adequate racking approximately every 2-3 months time. Try to minimize air contact with your wine while racking. You don't want to oxidize your hard work.
