Communicating with Your Wine…What did you say?

OK. So, I’ve got your attention… For just a few moments, I’m going to play the role of a self-help guru and point out how by learning to communicate with your wine, you will find that you have a better relationship with your wine and your wine will be all you ever hoped it would be.

Let’s first consider some of our everyday relationships and the significance of effective communication within those relationships.

Relationship #1: You and your dog ‚Äď Rover needs to be let out to do his business. How do you know?¬†Well, you listen him ‚Äď perhaps he makes certain noises that tell you? You watch him. Perhaps he stands¬†by the door to let you know. Your relationship with your dog is based upon visual and auditory cues. A¬†mistake in interpreting these cues could mean an accident that will need to be cleaned up.

Relationship #2: You and your baby ‚Äď You need to understand why it is that your baby is crying. If you¬†happen to be a parent, you know all to well the process of elimination through which we determine why¬†the baby is crying. Does the baby need to be changed? We accomplish this through sensory analysis;¬†touch via the finger test for wetness and smell to see if baby has a ‚Äúgift‚ÄĚ for us. It goes beyond this to¬†evaluating for gas, hunger, or even illness and with a baby the stakes are high.

Relationship #3: You and your significant other ‚Äď This has got to be my favorite to discuss. I say this¬†because it is the one relationship that I‚Äôll mention that actually includes the element of verbal¬†communication. You would think that a combination of body language and direct verbal communication¬†would equate to very effective communication. Yet, how many times have you said to yourself ‚Äď ‚ÄúWhat is¬†this person talking about? What? Huh? I just don‚Äôt understand what this person wants‚Ķ‚ÄĚ The important¬†point of this relationship is that even with lots of information, that information is only as good as our ability¬†to receive it, to make sense of it, and to respond appropriately. If we are not listening and do not know¬†how to respond we are destined to a relationship that is not as good as it could be or even worse ‚Äď a¬†complete failure.

Relationships are about communication. As you can see from the examples presented above, that communication happens in different ways and using a variety of cues. Relationships are improved through adjustment, more of this and less of that. However, the adjustments will only be effective if, in fact, they are the appropriate response to the communication. That requires developing the ability to effectively interpret the communication. Finally, relationships cannot be forced. In other words, there are times when we simply cannot make a person or thing into something that it is not.

I‚Äôm sure that by now you may be thinking ‚ÄúWhat does this have to do with wine?‚ÄĚ. Actually, it has a lot to¬†do with wine. From the time we purchase our grapes, the grapes have information to share with us ‚Äď if¬†we are willing to listen. We open the lines of communication by establishing that we care to know what¬†the grapes have to say. We do this by taking the appropriate measures for Sugar, Acid, and pH. For¬†instance, a must might say that it is a Cabernet Sauvignon, it has a Brix reading is 25, a TA reading of¬†6.2 g/L, and a pH of 3.5. Without fail we ask these questions of our must because we care to know how it¬†is doing and if it is positioned well to develop into a fine wine. We know that it will fair the best in yielding¬†a fine wine if it communicates numbers like the ones suggested above. However, what if your must¬†communicated a reading of 30 Brix, a TA of 4.4 g/L and a pH of 3.9? With these readings, our must¬†would be communicating‚Ķ‚ÄĚI need something from you in order to produce the wine you are looking for¬†and I need your help to do so! Please help.‚ÄĚ. We respond by making the necessary corrections and bring¬†our must into a state where it can communicate desirable numbers and subsequently produce a wine that¬†we can be proud of.

Now, please don’t think I’m suggesting the relationship that you have with your wine will be like those I used as examples. Nor should you anticipate your wine actually speaking to you. If it does, I assure you it is not normal and you might wish to seek some professional help. What I am suggesting to you is that like our other relationships, our grapes have information to share, if we care to listen, and that information can only help us.

It is a perfect one-sided relationship. The winemaker seeks to produce a wine according to certain expectations. We’ll assume the grape develops on the vine for no other purpose than to satisfy the desires of the winemaker. All we need to do is to make sure we maintain our lines of communication. We as winemakers take readings that extract the information the grape has to share. We evaluate that communication to determine if the particular must is capable of meeting our expectations. Perhaps it is capable as is, perhaps it will be capable with only a few adjustments, or perhaps it is simply not suitable for the type of wine we wish to craft. Armed with valuable information, we can take our relationship into a suitable direction.

The juicegrape.com web site has more material on gathering and making sense of the information your¬†grapes have to share. My purpose in writing this article was simply to point out that there is a relationship¬†between the winemaker and grape and like any other relationship, the best outcomes occur when the¬†communication is good and frequent. So, take those readings and do so regularly. Write them down. If¬†you don‚Äôt know what the readings mean, refer to the juicegrape.com website and have a good reference¬†book that will assist you in understanding what your grapes are communicating. Finally, have a set of¬†expectations for the wine you wish to craft. Perhaps the grapes you have can meet those ¬†expectations ‚Ästperhaps not. Either way, you are better positioned to work with the grapes in crafting a wine that can fall¬†within your expectations and a wine that you can be proud of.
Salute!

Shedding Light on Red Wine, Sulfites, and Allergies

 

Many people complain of getting headaches after drinking red wine. Although it is very arguable that some of these people simply had a bad experience drinking lousy wine or in overindulgence and now blame all red wines, there seems to be enough evidence to suggest that others consistently experience a real physiological reaction after drinking red wine.

The following article provides an excellent insight into what is known as red wine headache or RWH.

The Puzzling Red Wine Headache – By Marian Burros (originally published in the New York Times 2002)

For some people, a glass of red wine is an invitation to a roaring headache. After a few episodes of headache and queasiness, those who suffer them may banish wine from their tables for life. The symptoms are part of a syndrome known as Red Wine Headache, or RWH.

‚ÄúThe red wine headache is a real if poorly understood phenomenon,‚ÄĚ says an article in the June issue of the Harvard¬†Health Letter. That is a masterpiece of understatement. There are many theories about what causes the syndrome,¬†but few facts. Dr. Fred Freitag, associate director of the Diamond Headache Clinic in Chicago, said no one really¬†knows what leads a patient to develop this type of headache.

It may be caused by ‚Äúcompounds found in grape skins. They are either naturally occurring or produced through¬†fermentation,‚ÄĚ Dr. Freitag said. He would postulate no further. ‚ÄúIt‚Äôs not as if there are hundreds of thousands of dollars¬†for funding‚ÄĚ studies to determine the cause, Dr. Freitag said. There is actually a stigma to studying the subject. ‚ÄúI‚Äôve¬†entertained the idea of looking for grants to study this and I’ve been told, ‚ÄėDon‚Äôt go there, it‚Äôs bad P.R.,‚Äô‚ÄĚ Dr. Freitag¬†said. Bad publicity comes to those who would study drinking? Carry Nation is with us yet.

Sulfites used to take the blame for RWH. About 20 years ago the Food and Drug Administration determined that¬†about 1 percent of the population is allergic to sulfites and equired that wines containing certain levels of the¬†compound be labeled ‚Äúcontains sulfites.‚ÄĚ Many people have assumed, incorrectly, that the labeling is designed to¬†warn people who get a red wine headache. [In fact, sulfite sensitivity is a true allergy. Sufferers experience an allergic¬†reaction, but not a headache. RWH is something else.]

Scientists have pointed out, however, that many sweet white wines contain more sulfites than red wines ‚ÄĒ yet do not¬†cause headaches in those who suffer from RWH Additionally, dried fruits usually contain sulfites but you never hear¬†of dried fruit headaches. Sulfites can cause an allergic reaction [breathing problems], Dr. Freitag said, but they give¬†headaches only to asthmatics.

Other experts think tannins are at the root of the headaches. Tannins are the flavonoids in wine that set one‚Äôs mouth¬†to puckering. The Harvard Health Letter notes several well-controlled experiments showing that tannins cause the¬†release of serotonin, a neurotransmitter. High levels of serotonin can cause headaches and that may happen in¬†people who also suffer from migraine headaches. But that does not explain why people who do not get migraines get¬†RWH. Dr. Marion Nestle, chairwoman of the Department of Nutrition and Food Studies at NYU, added that no one¬†complains about tea, soy, or chocolate headaches ‚ÄĒ though all contain tannins.

A third school of thought blames histamines. Histamines are 20 Р200% higher in red wine than in white, and those who are allergic to them are deficient in a certain enzyme. Some experts believe that the combination of alcohol and that deficiency can cause the headaches. But a study of 16 people with an intolerance to wine, reported in the Journal of Allergy and Clinical Immunology (Feb 2001) found no difference in reactions to low- and high-histamine wines.

A fourth suggestion is that prostaglandins ‚ÄĒ substances that contribute to pain and swelling ‚ÄĒ may cause RWH.¬†[More on this next month!] Yet for most people who suffer from RWH, the hypotheses are irrelevant. They want to¬†know what to do about the problem. Some Web sites suggest prevention: for histamine sensitivity, pop a nonsedating
antihistamine like Claritin or take an aspirin to stop production of prostaglandins.

Dr. Freitag frowns on this. To lick the problem, he advises a potentially long, painful, and costly experiment. A sufferer¬†of the headaches himself, Dr. Freitag finds that he can drink some reds and not others. ‚ÄúTry different brands, different¬†grapes, different countries of origin. That‚Äôs the only way you are going to find out.‚ÄĚ Drink a half a glass of red wine; if it
is going to give you a headache, it will do so within 15 minutes. If there is no reaction, stick with that wine for the evening, keeping your alcohol consumption to no more than two glasses. Keep a journal.  And don’t confuse RWH with the headache that comes six hours after a full evening of drinking. That’s called a hangover!

A Possible Solution

So, for all those individuals who develop the red wine drinking debilitative RWH, is there any ray of hope? Well, it would appear that a study from back in 1981 provides some potential.  In 1981 Herbert Kaufman, M.D., reported that the prophylactic ingestion of aspirin prevented the red wine headache syndrome, RWH, (Lancet 1981; 1: 1263). He also noted that once RWH begins, aspirin has little or no effect in altering the headache. Five years later, in a non-controlled study, Kaufman reported that aspirin inhibited the
immediate and late phases of RWH, and the proposed mechanism was through interruption of prostaglandin synthetase (Immunology and Allergy Practice; 7: 279-84). In a new controlled study, Kaufman and Dwight Starr, M.D., Mt. Zion Hospital and Medical Center, examined, through blind evaluation, various inhibitors of prostaglandin synthetase (IPS) drugs, aspirin, Acetaminophen, and Ibuprophen, to test if the RWH could be prevented by the prophylactic use of these specific medications.

During the first stage, twelve subjects (nine females and three males) with a history of RWH were challenged with red¬†wine, and all experienced RWH. The subjects returned one week later, stage two, and were given inhibitors of¬†prostaglandin synthetase or placebo one hour prior to wine ingestion. The two who received the placebo were not¬†protected. Kaufman and Starr reported that ten of the subjects who were premedicated failed to develop the RWH;¬†two given Acetaminophen developed a “second phase” RWH 6-10 hours after wine ingestion.

Kaufman and Starr conclude that RWH may be due to a metabolic defect and corrected by prostaglandin synthetase inhibitors. Mechanisms of correction remain unclear.

Other possibilities…

Our online research uncovered some linkage between red wine headaches and the consumption of black tea. We won’t list a reference here simply because the specific association to RWH is associative at best. None-the-less, upon further examination of the claim, one will uncover that black tea contains a bioflavonoid called Quercetin.  Quercetin has the effect of inhibiting histamines and acts as an anti-inflamatory. While this may end up being a solution for some people, it should be noted that red wine is also cited as being a good source of Quercetin. Perhaps the components of wine are antagonistic and so the extra Quercetin will make the difference.

Along the same lines, additional claims linking bloating that results from wine consumption to complimenting the glass of wine with items like dark chocolate and unsalted nuts. Actually, those sound really good (although I prefer my nuts salted). Specifically, the recommendations points to increasing dietary intake of magnesium, which is said to have
anti-bloating effects. I personally do not believe Magnesium alone will do the trick, but it might help and in the forms suggested, probably wouldn’t hurt. Actually, I tend to believe partially from research and partially from experience that an aspirin before and copious amounts of water and a multi-vitamin afterward are your best friends for finding
yourself in top running order the morning after an evening of responsible wine-drinking.

Lest we not forget Sulfites…

The following article text was written by William Bincoletto and was featured in the Words on Wine section of the enjoycooking.com website (http://www.enjoycooking.com/wow_details3.php?wow_id=3).

What are sulfites?

Sulfite is a word used to describe forms of sulphurous acid, including sulphur dioxide. Sulfites have been used since ancient times for many purposes, including the cleansing of wine receptacles by both Romans and Egyptians. As food additives, they have been used since the 17th century and approved for use in the United States as long ago as the early 1800s. They are currently used for their preservative ability, which includes controlling microbial growth, blanching certain foods, and preventing spoilage of certain perishable foods, beverages and pharmaceuticals. It is their antioxidant and anti-microbial properties that have gained them an important role in wine making. The sulfites either inhibit or kill bacteria or wild yeast, thus encouraging rapid and clean fermentation of wine grapes. Sulfites are also a natural and minor by-product of yeast fermentation and thus are produced during the wine fermentation process.

Who is allergic to sulfites?

The FDA in the US estimates that one in 100 people is sulfite sensitive to some degree, but for the 10% of the population who are asthmatic, up to 5% are at risk of having an adverse reaction to the substance. More importantly, the most significant sulfite sensitivity reactions occur in susceptible asthmatics. From a public health standpoint, the
sub group of greatest concern is the sulfite-sensitive asthmatic population. Of those, the ones in whom the most severe reactions have been reported are steroid-dependent and are taking such drugs as prednisone or methylprednisolone. Most of these individuals have been cautioned by their doctor to avoid sulfite-containing foods or beverages. The number of asthmatic patients that are included in this sulfite sensitive group is estimated to be 500,000 in the United States. The USFDA requires labeling of foods containing 10 ppm or more of sulfites.

What are the symptoms of a sulfite reaction?

The symptoms of a sulfite sensitivity reaction vary from mild to life-threatening. The most common symptoms are mild and involve a skin rash accompanied by redness, hives, itching, flushing, tingling and swelling. Respiratory symptoms include difficulty breathing, wheezing, and stridor. Gastrointestinal reactions involve nausea and stomach cramps.
Much less common but more serious signs and symptoms of sulfite sensitivity are low blood pressure, shock, extreme difficulty breathing, and loss of consciousness. As noted above, these symptoms of a severe reactions are most apt to occur in the steroid-dependent asthmatic person.

I get headaches, stuffy nose, and rosy cheeks from red wine. Is this an allergic reaction?

Technically, this is not an allergic reaction. What is being described is usually referred to as the ‚Äúred wine headache¬†syndrome.‚ÄĚ This is not related to the sulfite content of the wine but probably due to other substances contained within¬†the wine such as histamines, tyramine, and phenolic flavonoids. Aside from the discomfort of the headache, these¬†symptoms do not appear to be a risk for progression to a more serious reaction. Studies have suggested that these¬†headaches can be avoided or minimized by taking either aspirin, ibuprofen, or acetaminophen prior to drinking wine.

I can drink only white wines. Do red wines have more sulfites?

Actually, red wines may have less sulfites. In 1993 the European Union passed regulations permitting higher levels of total sulphur dioxide in dry white wine than in dry red wine and an even higher level in sweet white wines and rose wines. The higher level in the sweet wines are necessary to prevent the further fermentation of the higher levels of
residual sugar. If you have a problem with red wines as compared to white wines, it may be related to the ‚Äúred wine¬†headache syndrome‚ÄĚ [which was described last month]. Or, you may just be unfortunate enough to have an¬†idiosyncratic allergy to one or more naturally occurring chemicals in some red wines. Experiment with small quantities
of various wines until you find some that don’t bother you.

To sum this up, it would seem that if a person were sulfite sensitive, their first experience would not have been from the consumption of wine. For those people who claim to both be sensitive to sulfites and only able to drink white wine, this is a contra-indication in that white and sweet wines will generally be ones to possess more sulfites.

I personally have a mold allergy that results in periodic sneezing from my initial consumption of alcoholic beverages and followed by various degrees of congestion. I get the same response for initial sips of brandy, beer, wine, and yes…even a recommended dose of cough syrup.

Be it RWH, sulfite sensitivity, or some other cause such as an allergy, it is certainly helpful to try to better understand the adverse physiological response and why it occurs. For those who truly enjoy wine and experience such adverse effects, perhaps the enjoyment outweighs the physiological effects and perhaps the cause is not what you once
thought.

Regardless of the cause, if you have experienced moderate to severe adverse effects from drinking or consuming any product, it would be best for you to seek medical evaluation before resuming consumption of that product or any of its variants. Your continued well-being is of the utmost importance.

Drinking Wine with Purpose…

Most of us are familiar with social context surrounding the consumption of wine. In most cases, wine is consumed with a group of people at a gathering of some sort, at dinner, or
perhaps as a relaxing way to begin a romantic rendevous…

Certainly, drinking wine is about improving the social experience, and allowing each individual the opportunity to travel to other places and experience richness they might not
otherwise know and without even needing to leave their home.

I could go off on a tangent as to how wine simply ‚Äúmakes things better‚ÄĚ, but that‚Äôs not the¬†focus of this article. In this article, I‚Äôm specifically examining how drinking wine can
impact a winemaker’s ability to craft wines that are both stylistic and received well by those who consume the wines.

Making wine and making it well, as with anything else, requires starting off with a clear goal of what it is you are setting out to do. What are you trying to make? Is it a Cabernet, or is it a Cabernet that can be described as a series of adjectives (related to taste and after-taste, aromatics, mouth feel, etc.)? Let me make another example…If I were a builder and you wanted me to build your house, would you get better results by requesting that I build you a Colonial or by requesting that I build you a Colonial and providing me with explicit blueprints for how that Colonial should look?

Simply put, the more information we have pertaining to the intended outcome, the closer we can come to arriving at that¬†outcome. Of course, in winemaking there are some elements outside our control ‚Äď particularly the elements of the grape¬†that come directly from the terroir.

As a winemaker, even if someone were to come to you and say ‚ÄúI want you to make me a full-bodied, fruit forward, and¬†soft tannin Shiraz‚ÄĚ, you would be hard pressed to know what that would equate to if you had not developed a mental¬†library of such characteristics. And how would you accomplish that? The answer is by the purposeful tasting of wine.

The American Wine Society (AWS) has developed a wine evaluation sheet for individuals to use at wine tasting events. It¬†is a good sheet that helps a ‚Äútaster‚ÄĚ perform a thorough evaluation of one or more wines. The goal of the sheet is to¬†provide guidance and metrics by which one wine can be compared to another for the purpose of competition. For a
winemaker looking to develop such a frame of reference, I personally believe he or she needs to gather much more¬†information ‚Äď much of which comes directly from tasting.

It can be argued that a good winemaker should spend at least a portion of his or her time approaching a glass of wine like¬†a detective. Prior to tasting, information like Country of Origin, Province of Origin, Intended Style, Varietal Composition¬†and Analytical measures like pH, TA, and Residual Sugar can all be recorded ‚Äď setting a backdrop for the tasting to
follow. Many commercial wineries now post readings like TA, making it even easier to obtain that information.

The ‚Äútasting‚ÄĚ that follows involves sight, smell, and taste. I believe this is where the ‚Äútaster‚ÄĚ and ‚Äúwinemaker‚ÄĚ diverge.¬†While both will access the overall appeal of the wine, the winemaker will process the characteristics to essentially¬†reconstruct the winemaking process that may have led to the wine being tasted. In some cases, the general characteristic
is not enough for the winemaker. For example, to say something is ‚Äúoaky‚ÄĚ may be insufficient for the winemaker to¬†translate into something of value. He or she will need to take that to the next level and describe the ‚Äúoakiness‚ÄĚ in more¬†detail‚ĶIs the oak taste more char-like? Is the oak more ‚Äúwoody‚ÄĚ? Is there vanillin present? The winemaker uses this
more detailed information to reverse engineer the wine ‚Äď in this case the type of oak that should be used to recreate a¬†similar wine.

My experience in this critical tasting suggests the tasting be done either alone or with fellow winemakers who have the¬†same mindset for a critical dissection of the wine being tasted. That is not to say that the end consumer has no value to¬†offer. On the contrary, they are likely to tell you they like or dislike a wine. The key is to uncover the specific¬†characteristics of the wine that have led to that conclusion and the tasting level or sophistication of the end consumer, and¬†to file that information away in your notes or mental library ‚Äď if you still have room.

After tasting and listening, a winemaker should be constructing a frame of reference for wines of a given area, given type,¬†given varietal, and what end consumers tend to like or dislike given their ‚Äúlevel‚ÄĚ or sophistication as wine consumers.

What remains for the winemaker, is to make sense of all this information and seek to connect the desired characteristics for the wine to be crafted with the cellar techniques that lend themselves to such characteristics.

That connection or bridge is quite comprehensive and falls outside the scope of this article. What I would suggest, for starters, is as follows; the next time you have a wine that you find exceptional, ask yourself what characteristics about the wine made it that way. Then, take one characteristic and begin to research what winemaking techniques might lend
themselves to such a characteristic. For instance, you might find you enjoy the smooth buttery mouth feel of a Chardonnay. Look to better understand what can make a Chardonnay smooth and buttery…

In closing, winemakers need to take sometime to critically evaluate wines to improve their ability to craft wines of a particular type or style. They also need to understand those characteristics in favor by those who would consume their wine. From time to time you will see that we at M&M make suggestions for wines to try based upon origin or variety. In
doing so, we are encouraging you develop a frame of reference. Once you have that frame of reference, you will then be ready to make the connection to winemaking techniques.
Do take some time to also just sit back and enjoy wine ‚Äď though the bug to evaluate it will soon overcome you.
Salute!
