Hello:
I am getting ready to start my first batch of wine from concentrate. I am a little confused about the sanitizing process for large pieces of equipment. The directions say to dissolve so much sanitizing stuff to one gallon of water. Does this mean a gallon will do the job? With a 6 gallon tuft tank or a 6 gallon glass carboy, for example, do you pour the gallon in the container and slosh it around? If so for how long? Directions say to soak corks from 5 to 10 minutes. Small items such as hydrometers can be submerged, but I am a little vague on doing the big items and some of the other details?
Thanks
Mike H.

Hello Mike,
Thanks for the great question… It is important to understand that all the equipment that comes into contact with the wine should be sanitized. This includes wine making equipment you may have gotten from us, as well as any stirring spoons, hoses and pans you may be using from around the house.
Before sanitizing you need to make sure that all items are soapy clean and void of organic grime from previous uses. This process is no different than washing dishes. After everything is soap-clean, then it can be sanitized.
These three items: sodium metabisulfite, potassium metabisulfite, and Campden tablets can all be used in the same way. Mixed with water they make a very good sulfite sanitizer. Just use one teaspoon per gallon, or in the case of the Campden tablets, use 16 tablets per gallon.
Not only does direct contact with these solutions sanitize, but their vapor will sanitize as well. What I will typically do is put all my hoses, gravity hydrometer, rubber stoppers and other smaller wine making products in my plastic fermenter bucket. Then pour in 2″ or 3″ of the solution. Place the lid over the top and let it sit for about 20 or 30 minutes. Longer times do not hurt. This will sanitize your smaller equipment as well as the inside of your plastic fermenter.
You can sanitize the inside of glass jugs and wine bottles in the same way. Just pour in an inch or two of the sulfite solution, and let stand for 20 or 30 minutes. Lightly drain the jugs or bottles, and they are ready to be filled with wine.
With larger wine making products that will not fit in the fermenter, a contact sanitizer such as our CleanPro SDH or One Step No-Rinse Cleanser should be used. Unlike the sulfite solutions, these sanitizers require actual contact time. You can use your kitchen sink, however it should be soap-clean and sanitized first.  To sanitize just fill the sink with a gallon of the sanitizing solution. Use this solution, liberally, with a clean rag to wipe down all the sink’s surfaces and any counter-top areas you plan on using.
Now you are ready to sanitize your wine making equipment. Drain the sink and mix up a fresh batch of sanitizer in the sink, again use a clean rag to wipe down the equipment. Keep submerging different parts of the equipment while wiping down exposed parts with the rag. Do this for 15 to 20 minutes and it will be ready for use.

Hi there,
I am a recent homebrewer turned winemaker. I was wondering if it was appropriate to filter the wine before bottling. I am making a European Select Verdicchio at the moment. I have a 10 inch sediment filter unit with either a 0.5 or 1.0 micron filter. Can I put wine through this and is it worth it? Thanks, any help would be great.
Regards,
Dean R.

Dear Dean,
There are many advantages to making wine using our concentrated juices such as the European Select you are using. One of the more significant ones is that all of the solid particles in these juices have been removed. What this means for you, as a home winemaker, is that the only sediment that you will need to deal with is what is created by the yeast.
If given enough time, these yeast cells will settle to the bottom of the fermenter with the additional aid of some clarifiers that are included in these juice kits. So, filtering is not necessary just as long as the wine is not rushed along and given enough time to clear on its own. This is easily accomplished by following the time-table provided in the directions that come with these juices.
Where wine filtering can play a real beneficial role for concentrate wines is in the visual aspects of the wine. While these finished wines will look completely clear and beautiful as is, running them through a wine filter will add a polish or luster that almost seem illuminating.
I personally do not filter all my wines, but I do make sure that any wine I plan on passing out as a personalized wine gift is filtered. I put custom wine bottle labels on them and they are ready to pass out and impress.
To sum this up, when it comes to learning how to make your own wine, filtering is not on the top of the list, and a wine filter will probably not be the first piece of homemade wine equipment you should purchase, but you will certainly want to consider filtering your wines, eventually, particularly if you plan on sharing them as wine making gifts with decorative wine bottle labels and such.

[Editor’s Note: For those of you not familiar, an ice wine is a wine made from the juice of frozen grapes. Most of the water in the grapes is frozen but the sugar is not. When a winery runs them through the grape crusher and grape presses, the result is a very, very sweet grape juice that will make a wine with high alcohol and a lot of flavor.]

Hi,
I have some lake niagara grapes that I am interested in trying to make an ice wine recipe.  They are in the freezer currently.  Do I make it the same as a grape wine or is there some other step in the process that I have to do?  Any info you can give me would be appreciated.
Thanks,
Mark O.

Dear Mark,
What you are actually attempting to make is an icebox wine not an ice wine. The difference being, you are using artificial cold to freeze the grapes as opposed to leaving them on the vine and waiting for Mother Nature to do the freezing for you.
To answer your question, there is really not too much difference between making an ice wine and making any other grape wine. The basic steps are the same, except for the fact that you will be putting the grapes through a grape crusher and your grape presses before fermentation. The skins will not be in the fermenter at all. This is because the ice is with the pulp at this point.
The whole goal with ice wines is to get as much sugar out of the grapes while getting as little of the water. Freezing the grapes works out good for this purpose. Water freezes at a higher temperature than sugar does, a phenomenon known as fractional crystallization.
By bringing the grapes down in temperature to around 15F. to 20F. you are freezing mostly water. The grapes are then ran through the grape crusher and pressed as quickly as possible. An extremely sweet juice comes out of the press while the skins, pulp and ice stay in the press and are later discarded.
Having a refractometer to monitor the sugar concentration of the grape juice at this stage would be beneficial. You are looking to get a brix reading of at least 35 degrees. This is the minimal level used by commercial wineries in Canada — Canada being the biggest produce of ice wine in the world.
I hope this information helps you out. Just remember that it is really no different than how to make white wine, only the grapes are cold and stiff.
Best Wishes,

Have you ever wondered where all the sediment in the bottom of your fermenter comes from?
We’re not talking about the strands of pulp and other bits of the fruit, but that creamy, brown-looking stuff at the very bottom. Is it the broken-down solid remnants of the fruit? No, it even shows up when you make your wine from pulp-free concentrates! Could it be sugar that was added to the juice? No, the sediment’s there even when no sugar at all has been added to the must. So what is it? Where did it come from?
Here’s A Shocker. Remember back when you started the wine and you were adding all the wine making ingredients, just like the homemade wine instructions said to do? One of the ingredients that you added was in a little foil packet about 1-1/2 inches square–the wine yeast. That little packet is what produced all that sediment.
Once the yeast begin to ferment, they start multiplying by a process known as budding. In fact, in a 5 or 6 gallon batch of wine, the wine yeast will typically multiply themselves by about 100 to 150 times the little packet you added. This means you could have well over a pound of sediment just from the yeast alone. Wow, that’s freaky!
Well It Gets Freakier: Even if you add two packs of wine yeast you do not get two times the sediment. You will get more for sure, but only a minor, marginal amount. This is the nature of wine yeast. It propagates itself only to the level necessary to complete the fermentation.
This makes it near impossible to add too much wine yeast. Whether you add one, two or three packs to a 5 or 6 gallon batch of wine, the results are virtually the same.
So now you know…

Hello Kraus,
I made my first batch of homemade blackberry wine and it was too dry, so I put in a bottle of your Wine Conditioner, tried it and it was still too dry.  So my question to you is if I mixed up some sugar water and put it in would it re-ferment again or not .
Thanks Bill
———-
Dear Bill,
Wine Conditioner is one of those wine making products that makes the winemaker’s job so much easier. It is fructose and glucose sugars that have had Potassium Sorbate added to them. The Potassium Sorbate acts as a stabilizer that will keep the wine from fermenting again with the newly added sugars from the Wine Conditioner.
The amount of Potassium Sorbate needed to keep a wine stable is not dependent on the amount of sugar that has been added to the wine. It is dependent on the volume of wine that is being stabilized. In the case of Wine Conditioner, as long as you have added 1/3 of the bottle to a 6 gallon batch, there is enough Potassium Sorbate in the wine to keep it completely stable regardless of how much sugar you add.
So to answer your question, you can add all the sugar syrup mix you like without worrying about a re-fermentation because of the Potassium Sorbate you’ve already added by way of the Wine Conditioner. This is one of those neat, little wine making tips for the home winemaker who is trying to economize a little bit. As long as enough Wine Conditioner is used, you will not have any issues with re-fermentation.
I would like to point out here that wine making products such as Wine Conditioner are made specifically for wine. The fructose and glucose sugars sweeten the wine differently than regular, store-bought cane sugar does. This is something you need to keep in mind when deciding whether or not to utilize economizing wine making tips such as this one. Flavor may be an issue.

Hello:
I recently read an article on your website that said not to use distilled water, but bottled water labeled spring water. Should I treat the water with sodium metabisulfite before beginning the primary fermentation in my plastic fermenter or is the bottled spring water okay to use straight from the bottle?
-Shawn S.
———-
Dear Shawn,
Deciding if you should add Sodium Metabisulfite before the fermentation or not isn’t determined by the type of water you use. Regardless if it is bottled spring water or just plain tap water, it does not make a difference. Either water is fine and does not require the addition of sulfites.
What does matter is whether or not you are making wine from fresh fruits. When making wine from fresh fruits, sulfites should be added before the fermentation to destroy any wild molds, bacteria, etc. If you are making wine from a packaged wine making juice of some kind, then there are no wild molds or bacteria to be delt with, so no sulfites are needed.
Sodium Metabisulfite is added 24 hours before you add the wine yeast. During this time the sulfites release into the must and then slowly disipate into the air. This is why you only want the fermenter to be covered with nothing more than a light towel. Once 24 hours has past, you can then add your wine yeast. If you add the yeast before this time, you run the risk of killing the yeast with the sulfites.

Hello
My name is Rachelle–my boyfriend and I are hobby wine makers and recently discovered your website last fall–WE LOVE IT 🙂  We do have a question, however, regarding the proper technique during bottling that we can’t seem to find a straight answer to. 
We have been bottling directly from our wine filter, and are first wondering if that is okay, or if we should let the wine sit a few days after filtering before bottling?
The second question, should we try to minimize the amount of “bubbling” during bottling.  I mean should we try to bottle by allowing the wine to gently fill down the side of an angled bottle so that there is little surface disruption/aeration, or if we can just point the hose down, shoot and fill it up so there is oxygen mixed with the newly bottled wine.
If you could please let us know, it would be greatly appreciated.  We have a few more weeks until our next bottling, but would like the input.  Thank you kindly.
Sincerely,
Rachelle

Dear Rachelle,
Both of your questions can be answered with the same reasoning: you never want to splash a finished wine in a way that allows air to saturate into it. This is particularly important when learning how to make white wines. Air is the fuel for oxidation, a condition that can cause a wine to turn brown or orange. In the case of white wines oxidation is easily noticeable, but it can also be troublesome for reds.
Relating this issue back to your question about bottling homemade wine straight from the wine filter, doing so is very difficult to do in a gentle way. Wine is more easily wasted with this method as you move from one bottle to the next, and splashing is certainly more prevalent.
It is much better to transfer the wine from the wine filter to something like a plastic fermenter that has a spigot. Once you are done filtering the wine you can attach a piece of vinyl hose to the spigot and start filling the bottles from there.
Regarding your second question about how to get the wine into the wine bottles, the ultimate way is to fill the wine bottle from the bottom up. In the instance of using a piece of vinyl hose attached to a spigot, shove the hose all the way to the bottom of the wine bottle when filling. The idea is to keep the end of the hose down into the wine. This will eliminate virtually all the splashing. You can turn the spigot off between bottles to save making a mess.
We do have additional wine making products that make bottling homemade wine a little easier. One of them is a filling rod that can turn the flow off automatically between bottles. It’s call a Bottle Filler. It’s a long piece of clear, rigid tubing that fits on the end of the vinyl hose, like a wand. The other end has a button on the end that you press against the bottom of the wine bottle to start the flow. Once you lift up on the bottle filler, the flow automatically stops.
I hope this information is what you where looking for, Rachelle.
Happy Wine Making

Hi E.C.,
I’m making my first wine ever with your starter kit and my own wild grapes. I have your plastic fermenter that came with the kit, but I bought one of your glass jugs for secondary. I just started the secondary fermentation and I am not sure if I should continue to stir daily. I assume once the air lock is on I should just leave it alone?
Thanks,
Luke
———-
Dear Luke,
Once all the wild grape pulp has been removed from the fermentation, there is no need to stir the fermentation daily. Removing the pulp is something you should have done when you moved the fermentation from your plastic fermenter into the 5 gallon glass carboy for secondary fermentation. This is done simply by syphoning the wine into the secondary container and leaving the pulp and sediment behind. This is a process called racking.
The purpose of stirring the fermentation is to make sure that the pulp does not form a dried cap on the surface of the liquid. The dried cap can interfere with the wine yeast’s supply of oxygen, making it hard for the yeast to multiply itself into sufficient numbers. By stirring daily, any cap can be broken up and mixed down into the juice. In the secondary fermentation there is no pulp and therefor no reason to stir.
Best Wishes,
