I started on the reading material for my class last evening. The first chapters are the “technical” ones, first biology : the vine, its parts, how it lives, what it needs, photosynthesis and all that. Then, it’s chemistry : fermentation, alcohol, sugar, blue meth,… It’s all well and good if you ignore the fact that I hate science. Chemistry and physics were the two classes I always dreaded in school and to this day I feel nothing but apathy at best and loathing at worst for science.
But, wine science serves a greater good, so studied on I did. I was reminded of a quote by Rabelais, 16th century French philosopher ( a class I didn’t dread in school) about “Science sans conscience n’est que ruine de l’ame.” Science without conscience is just ruin of the soul. If you switch “conscience” with “purpose” in the quote, then you get something. Science for wine isn’t too bad, it serves a purpose, the purpose tastes good. I’m willing to see science as a necessary evil if it leads to grapes being fermented. Also, topically, Rabelais is often associated with good food and wine, especially Chinon wines from the Loire Valley, coincidence ? I think not.
Having reconciled myself with science, I kept studying. A big challenge is going to be the vocabulary, since I’m learning english words whose French translation I don’t know. It’s a process, nothing a little googling can’t solve. I am now familiar with buds, nodes, canes, spurs, shoots, tendrils and of course, permanent wood (not to be confused with transient wood which just phases in and out of reality). Okay, vines are plants, roots go down, sun comes in, photosynthesis happens, the plants grows. Everybody wins.
It gets more interesting when the lesson moves on to grafting. Basically, every vine producing grapes for wine is the result of grafting. Grafting is the process of joining 2 species of vines together to get qualities from both. Example : vitis vitifera is a vine that can produce wine grapes, which is good, but it is really fragile against the phylloxera parasite, which is bad. In fact, it those little bastards almost destroyed european vines in the 19th century. Enters vitis berlandieri, its grapes are unfit to produce wine, which is sad, but its roots can stifle phylloxera parasites by filling their greedy little mouths with sticky sap, which is good (and also really funny). Grafting the top of vitis vinifera on some vitis berlandieri roots, you get a vine that produces good grapes and can resist phylloxera. Jesse, you take this one.
Thanks Jesse. Now I’m starting to look at the scary part for me : chemistry. Compounds and reactions, fermentation, stuff turning into other stuff because stuff happens. I’m not kidding, “stuff” is an accurate snapshot of my knowledge level here. I’ll have to take copious amount of notes. I can’t wait to get to the part of the class where there are maps. I like maps, I understand maps. In the meantime, onward, for science !
