Storage manufacture grape concentrates, other products and waste from the wine industry

A question that crossed my mind lately was whether or not a winemaking kit could actually expire. In this blog post, I will provide my findings on this question and explain how to properly store your kit to make it last as long as possible among other tips for winemaking kits. Wine kits will usually last for a very long time, often between months. Over time wine kits will lose some of their properties, but will rarely have health risks even if you use them after expiration dates.

Vinegar Culture How to make vinegar? And what can you do? Do you have to throw away your entire batch, or is there some way to fix the problem?

When you face something like this, do not feel bad, and do not discard the wine. Regardless of how strangely your wine may behave, you are not the first person to experience the problem. The good news is that the failure rate of kits is very low.

If you follow the instructions closely and have generally sound sanitation and storage practices, along with a healthy dose of patience and the good sense to take and record specific gravity and temperature readings, the chances are that you will make good wine However, failures do occur.

That is when it is time for troubleshooting. We address the major types of problems primarily fermentation and visual and odour issues below, but your first recourse should always be to carefully re-read your kit instructions. Winexpert kits sometimes have instructions and procedures that contradict accepted techniques for fresh grape winemaking.

There are many good reasons for these non-intuitive procedures, but they all boil down to the same thing: our numerous laboratory trials have shown that these methods best produce fermentation, clearing and stabilising. And the number one reason that our Quality Control laboratory sees for kit failure is departure from the steps in the instructions. Logically, it seems that techniques used for grapes would work best for kits as well, but that turns out not to be the case.

Not only does this apply to the difference between the instructions for kits and fresh grapes, but it also applies to instructions between different manufacturers kits.

If you are used to one kind of kit, that does not mean you can apply its typical instructions to another. The best way to ensure the greatest incidence of successful kits for the largest number of users is to follow the instructions that come with a particular kit, as carefully and accurately as possible. Keep two important things in mind. First, you will need a good floating thermometer, a test-jar, and a hydrometer. These are essential for checking temperatures and specific gravity readings under normal circumstances, but you will definitely need them to troubleshoot your wine kit problems.

Secondly, the key to the cure in most cases is prevention. So even after you have fixed a problem with a current kit, the best way to improve your winemaking in the future is to keep good, careful records. Eventually you will be able to diagnose many of your own problems or repeat your successes, and avoid future problems altogether. Fermentation Problems Wine Won't Start Fermenting When yeast is pitched according to kit instructions, you should see activity within 48 hours, or at least see a nice, healthy scum of developing yeast on top of the must.

If you do not, the first step is to take a specific gravity SG reading. If it shows a drop from the original, you are experiencing 'secret' yeast. For several complex reasons, sometimes yeast like to get quietly to work without much foaming or fizzing.

In this case, the immediate solution is to wait and take another SG reading a day later, to confirm the progress of fermentation. If the gravity has not dropped, double-check that you have actually added the yeast.

On the first day, sometimes the multiple activities expected of you adding the right amount of water at the right temperature, stirring in additives, etc. If you find your package of yeast sitting inside the box, or think you may have discarded it, add yeast immediately.

If you can not find the package that came with the kit, make sure you add an identical strain to the one originally in the kit; it is the only way to be sure that your kit turns out the way it was intended to.

Check your gravity for the next three days to make sure that fermentation is proceeding correctly. If you know you added yeast, and it still is not fermenting, check the temperature of the must. Cool the must by freezing a couple of bottles of water, sanitising them on the outside, and dropping them into the fermenter.

Alternately, you can drape a wet towel or T-shirt around the fermenter and direct the breeze from a fan at it this technique is great for unexpected heat waves as well. When the temperature is below the recommended maximum in your instructions, go ahead and pitch a fresh package of yeast. Do not set it on a heating pad or blanket: this concentrates the heat and can cause electrical damage, or even a fire not to mention what it would do to the wine.

Most of the time, the yeast will recover and begin fermenting on its own within 24 hours, but if not, double-check the temperature of the must, and pitch another package. There is a definite window of opportunity for correcting the must temperature or adding a missed package of yeast: if you catch a non-fermenting kit within four days, you can probably get it going without repercussions.

Keep in mind, however, that unprotected grape juice is an excellent growth medium for all kinds of bacteria. If the must smells sour, or looks mouldy see the sections below on clarity and odour problems , you are probably out of luck. In any case, monitor your fermentation for signs of contamination during the rest of the process.

If you have added the yeast, the temperature is fine, and it is still not fermenting within hours, have a careful look for the additive packages that came with the kit.

If you have accidentally added the stabilisers to the kit, you may have a terminal problem on your hands. If you have only added the sulphite, sometimes a very strong yeast starter culture can overcome moderate levels of free sulphur dioxide. Shake the juice and nutrient mixture before adding the package of yeast, as a little dissolved oxygen will help the yeast get started.

After 24 hours, or the onset of very vigorous activity, pitch the entire quart into your must. Do not worry about changing the flavour; any change would not be significant, and a small flavour change is less important than getting your must started as soon as possible. Look in the section on odour problems, below. Another good restarting techniques is to take a wine from another kit that is ready to be racked from the primary fermenter to the carboy, and harvest the yeast sediment remaining after the wine has been racked.

By far the best way to do this is to leave the yeast sediment in the primary fermenter and pour the non-fermenting must in on top of it. Finish up with a good stir, to get all of the yeast cells into suspension.

This will be a rich source of very active yeast, and should restart just about any fermentation it is added to. If, rather than adding the sulphite, you have mistakenly added the sorbate package included in the kit, discard the wine.

Sorbate prevents yeast breeding, and virtually all efforts at starting fermentation in the presence of sorbate end in failure. If you have avoided all the above conditions, and your wine still would not ferment, your yeast may have been inactive; a fresh package should get things on the road. Make sure it is the same variety and type of yeast included in the kit, or you may not get exactly the results intended.

One thing that may seem like a good idea, but actually does not work with wine kits, is adding extra yeast nutrient. Winexpert adds very nearly the maximum amount of yeast nutrient a kit can handle. It is not going to be a low-nutrient situation that hampers your fermentation, and extra nutrient not used by the yeast will stay behind in the wine, and will leave a salty-bitter flavor. Try the wet towel trick described above, to cool it down.

The trouble with hot fermentation is that yeast tends to generate its own heat after a certain point, and you could have a heat-related yeast die-off and a stuck fermentation later. If your wine ferments to dryness in less time than specified in the kit instructions, please wait the minimum amount of days indicated in the instructions before racking to the secondary fermenter.

For example, if the instructions say to wait 5 to 7 days, until the gravity is below 1. This will ensure that an appropriate amount of sediment is left behind in the primary, and could prevent problems with fining and clearing later. Once in a while we see a kit that has been racked to the primary too soon, while having a large amount of oak chips still in suspension. These can collect in the airlock and block it off, causing pressure to build up, until suddenly the whole thing bursts.

If you do find your wine shooting out of the airlock, you have racked it into the carboy too soon. Rack it back into the primary and wait for it to hit the correct gravity.

Do not be fooled if it calms down immediately after racking. All that has happened is that the CO2 has been knocked out of solution by the agitation of racking, but the wine will soon be foaming vigorously again. If your fermentation is proceeding too slowly, try warming your must up to the recommended temperature, and practice patience.

Do not rack the wine on day 7 if the specific gravity is higher than recommended in the instructions. Wait for the appropriate gravity. One thing we frequently see hampering fermentation schedules is repeatedly fluctuating temperature.

Most of us never think about it, but when we leave for the day we turn the furnace off, dropping ambient temperature in our fermentation area, and when we come home, we warm our house up. This drives yeast crazy, and it can often cause it to go dormant, while it waits for more favourable conditions. You may need to isolate your fermenter in an area with a more steady ambient temperature. Wine Won't Quit Fermenting Sometimes a carboy will continue to bubble and bubble, long after it should have stopped.

First of all, check your specific gravity. If it is high, give the wine a good stir, make sure the temperature is at the high end of the specified range. Then practice patience yet again. If the SG is in the right range, as listed in the instructions, you may be experiencing one of two phenomena. First, your wine may actually be finished fermenting, but due to changes in temperature or barometric pressure it is out-gassing carbon dioxide at a rate that looks quite like active fermentation.

This could be exacerbated if your wine fermented quite slowly as in a cool fermentation , and is saturated with CO2. How this works with temperature: CO2 is soluble in a liquid solution in inverse proportion to the temperature of the solution.

When a can of soda is ice-cold, it barely hisses on opening. When it is hot, it gushes from the can as the trapped CO2 tries to exit as rapidly as possible. If your wine finishes fermenting cool, and then warms up, it may expel the gas quickly enough to mimic active fermentation.

How this works with barometric pressure: The sixty-mile deep layer of air above you presses down and keeps the pressure on you and everything around you at about 15 pounds per square inch at sea level. This pressure of air also squeezes the carbon dioxide in solution in your wine kit.

Under high pressure conditions clear skies, sunny the CO2 stays in solution. If there is a change in the weather dropping barometric pressure, cloudy skies or rain then the pressure lessens, and gas comes out of solution, again mimicking active fermentation.

Troubleshooting Wine Kits and Instructions, Prevention and Measurements

By Jun Wang, Arun S. With high moisture and sugar content, fresh grapes respire and transpire actively after harvest, which contribute to quality loss. Drying can process grapes into raisins for longer shelf-life as well as dehydrated grapes, which can be used for wines or juice production.

The intensification of the Vitis vinifera crop over recent decades has led to a continuous vineyard renewal, which has caused the disappearance of many indigenous minor grape varieties. Nevertheless, consumers today are looking for particular wines with enhanced varietal aroma. In fact, different landrace minor varieties have been recently authorized for winemaking in various Spanish Appellations of Origin AO ie.

The beverage industry consists of two major categories and eight sub-groups. The non-alcoholic category is comprised of soft drink syrup manufacture; soft drink and water bottling and canning; fruit juices bottling, canning and boxing; the coffee industry and the tea industry. Alcoholic beverage categories include distilled spirits, wine and brewing. Although many of these beverages, including beer, wine and tea, have been around for thousands of years, the industry has developed only over the past few centuries. The beverage products industry, viewed as an aggregate group, is highly fragmented.

Grape Drying: Current Status and Future Trends

The tradition of wine-making goes back thousands of years. In fact, the earliest historical evidence of wine production points all the way back to about the year B. It appears that the ancient Egyptians imported grape vines from the areas that are present-day Israel and Jordan to develop their own wine industry. This can also be said for the production of fruit juices. Fruit juice may, however, be thickened to a concentrate and re-diluted during the production process. This is done to save on storage and transportation costs. Besides these high-grade fruit juices, other beverages are also produced that only contain a portion of real juice and are diluted with water and sugar. These are less expensive to manufacture than pure fruit juices. Whole stone fruit with pits such as cherries, apricots and plums can be conveyed, as well as frozen raw product mashes or any other type of mash, pulp, yeast, distillate, concentrate or marc. Our industry specialists will assist you in selecting the perfect pump for your specific conveying needs.
