The dust was given to me in a mason jar by my girlfriends father, complete with no instructions. Just toss it across the whole of the vine like he does his peach trees. So that is what I did. If you don't have anything more constructive to offer than your sarcastic critisism, please keep it to yourself. = Paul = Sheesh.....besides poisoning our world, you are too effing careless to effectively use even a sockpuppet, Ima Paul Dudley Goodguy. I'm sure as hell glad you aren't my neighbor, Poisoner of Bees, Spiders, Butterflies and Other Helpful and Harmless Living Creatures.....such as your Neighbors!! Charlie Get a life, Charlie. Offer CONSTRUCTIVE advice or join the ranks of the "holier than thou" For example, there are a LOT of bee keepers who use chemicals every bit as risky as the OP used. Has ANY one of you doom and gloomers ever given the advice such as CONTACT YOUR LOCAL AGRICULTURE EXTENSION AGENT and ask for THEIR advice and opinion. Of course not. You have your own agenda. |

I have written gardentech.com ( the company that forced me to use their dust ) and am waiting their reply. = Paul = Paul, since you are making wine I offer the following information. "Organic wine" may be hazardous to your health - depending on the wine makers practices. For example, if SO2 is not used, if the pH of the must is above 3.5, if there is extended contact with the lees, If cultured wine yeast and ML bacteria are not used then the probability of the formation of carcinogens is enhanced. Here is a post I contributed to the wine making news group: +++++++++++++++++++++++++++++++++++++++++++++ I always look for articles indicating positive health benefits of drinking wine and indeed there are many. I recently came across an article in "Practical Winery & Vineyard" by Robert Tracy with the heading of "Human health concerns associated with wine microorganisms" (pp 96-98). The partial information I summarize below is NOT an attempt to start religious wars over technique or scare anyone but to raise some concerns that we as wine makers/growers should know. Personally, I believe there are "probably" more health related issues in a can of soda than some of the material discussed below but perhaps we can make better wine if we are aware of some of these facts. Summary and quotes: "From a winemaking perspective, there are two types of compounds produced by wine microbes that have health implications for the consumer: biogenic amines and ethyl carbamate.**Biogenic amines have been shown to cause negative physiological effects in allergic humans (such as headaches, nausea, hot flashes), while ethyl carbamate is considered to be a probably carcinogen to humans.**The*probable*carcinogenic properties of ethyl carbamate are based on studies with experimental animals, there is not direct evidence of it causing cancer in humans." "The concentration and type of biogenic amines vary greatly in wines; however, generally red wines contain significantly more than white wines.**In*addition,*there*appears*to*be*a*direct correlation between elevated biogenic amines in wine, wine spoilage constituents (such as acetic acid, ethyl acetate, butyric acid, acetoin, and higher alcohol compounds), and malolactic fermentation." Because ethyl carbamate is a probable carcinogen, it is becoming the focus of international regulation, and so its formation must be managed properly both in the vineyard and during the winemaking process." "Even though both yeast and bacteria can generate precursors for ethyl carbamate formation, urea produced from wine yeast is thought to be the major precursor." Factors that affect formation "Throughout the winemaking process, a whole host of factors can influence the formation of biogenic amines including: 1)**initial*microbial*populations*present*on grapes; 2)**presence*of*precursor*amino*acids*in*grape juice; 3)**ageing*of*wine*on*wither*yeast*lees*(sur*lie ageing) or lees following malolactic fermentation; 4)**extended*grape*maceration; 5)**spontaneous*malolactic*fermentation*by indigenous lactic acid bacteria; 6)**number*of*lactic*acid*bacteria*that*are decarboxylase-positive: 7)**wine*pH; 8)**concentration*of*sulfur*dioxide*(SO2) following malolactic fermentation and during ageing; 9)**winery*sanitation*practices; 10)**yeast*strain;*and* 11)**fining*practices*(fining*white*wines*with bentonite may remove biogenic amines). Among these factors, it has been demonstrated that malolactic fermentation is the primary stage for biogenic amine formation during the winemaking process. Ethyl carbamate formation is affected by the following factors: 1)**argine*content*of*grapes; 2)**concentration*of*ethanol; 3)**nutrient*additions*to*must,*during*both alcoholic and malolactic fermentaitons; 4)**yeast*straiin; 5)**spontaneous*malolactid*fermentaion*by indigenous lactic acid bacteria; 6) ageing wine on yeast (lees (sur lie ageing); 7)**temperature*of*iwne*during*ageing*and shipment; 8)**duration*of*wine*ageing; 9)**wine*pH;*and 10)**wineery*sanitation*practices." "Recommendations to prevent formation of biogenic amines and ethyl carbamate Biogenic Amines if possible periodically monitor microbial populations on grapes to determine risk for biogenic amine producers. if possible, assess concentration of primary precursor amino acids in grapes and must. avoid spontaneous alcoholic fermentations and use commercial strains of Saccharomyces cervisiae that lack or have minimal decarboxylase activity. Avoid extended ageing of wine on yeast or malolactic lees. Try to minimize extended grape maceration. Avoid spontaneous malolactic fermentations and use commercial strains of Oenoccus oeni that lack or have minimal amino acid decarboxylase activitry. Try to avoid higher pH wines (above 3.7) since they allow proliferation of Lactobacillus and Pediococcus. When pH of wine is high, lysozyme can be added to remove the natural lactic acid bacteria. Immediately following malolactic fermentaion and during wine ageing, maintain molecular SO2 levels of at least 0.4 to 0.5 ppm to prevent or minimize growth of lactic acid bacteria. Maintan good sanitation practices during wine production. Ethyl Carbamate Avoid argine content of 1000 mg/L in juice. Avoid excessive nitrogen fertilization of vineyards. Periodically monitor nitrogen status of vines and soil. Test nitrogen status of juice. Avoid adding excessive nitrogen supplements; do not add urea. Use commercial strains of Saccharomyces cervisiae that are known to produce low levels of urea (Premier Cuvee (PdM) or Lallemand 71B) when juice has a high arginine content. Avoid ageing wine on yeast lees (sur lie ageing), which can liberate amino acids and proteins. Avoid spontaneous malolactic fermentatons and use commercial strains of Oenoccus oeni that do not have ability to produce high levels of citrulline. Avoid elevated temperatures during ageing and shipment of wine. If wines are going to be aged for an extendd period of time, it is advisable to periodically monitor ethyl carbamate levels. Try to avoid higher pH ines (above 3.7) since they allow proliferation of Lacto bacillus and Pedioccus. Immediately following malolactic fermentation and during wine ageing, maintain molecular SO2 levels of at least 0.4 to 0.5 ppm to prevent or minimize growth of lactic acid bacteria. Maintain good sanitation practices during wine production." I realize that amateur winemakers do not have the resources to monitor all of the above but we can control a good amount of them.

For example, there are a LOT of bee keepers who use chemicals every bit as risky as the OP used. Golly, I guess that makes it just hunky-dory okie-dokie to spread poison about the planet. Thanks for the heads up and the excellant argument justifying the use of such, Paul. Tell me, how do you feel about irradiated food? :-) I gots me all sorts of them kinds of questions I would like to ponder you head with, but I thinks I gots yer number already, son. ;-) Has ANY one of you doom and gloomers ever given the advice such as CONTACT YOUR LOCAL AGRICULTURE EXTENSION AGENT and ask for THEIR advice and opinion. "I'm from the gummint and I am here to help you".....uh huh, oh yeah! They do have some good plans for hogsheds, though. This statement of yours shows your lack of understanding or care about such things as three-legged frogs and declining bird populations and cancers and all sorts of funky shit that is happening on account of, well, you know. But I didn't get this information from monsatano or dow or bayer or any of their front guys, like the usda and fda and....so I guess it is just doom and gloom bullshit. Of course not. You have your own agenda. Yep, that agenda being the speaking out about the use of toxins that contribute to the toxically over-burdened planet and that contribute to the bodily toxic load we and our children and grandchildren must suffer on account of the ignorance and greed of people such as yourself and the sockpuppet and all the minions of the agrochemical cartel who advocate the use of toxins. Hmmm....I wonder how wine was produced before the advent of carbaryl? Doom, Doom, Doom....can you hear the drums, Paul? Charlie "You just caught me on a good night. I'm doing what I was made to do - and I've got a feeling I'm going to do it even better this time" - Captain Billy Tyne Charlie I gave the OP advice on how to obtain the answer to his question - NOT - NOT I repeat my personal opinion. To summarize I have said: 1) Contact the manufacturer. If they say it is safe that does not mean that one should stop there. If they say chuck the grapes then by all means do it. 2) I suggested calling the viticulture experts at Virginia tech and or making the wine and sending them a sample for testing. 3) Contacting the OP's local agriculture extension agent. YOU have given YOUR personal opinion based on nothing but shit house rumors and NOT science. |
