We have a mobile cross flow filtration business in the Willamette Valley in Oregon. We use a 2008 Koch machine with hollow fiber cartrdiges which will remove particles to .2 microns. I recently had a winemaker note that he thought the Pinot we filtered took out some of the "greeness" of the tannin profile in his 07 wine. (A vintage known for unripe fruit in some cases.) Is there any science to support this claim, and how does the filtration process affect structure in our Pinots?
I met a wino a few weeks ago who spouted a term at a lecture that described the color deficient qualities of Nebbiolo, Pinot noir and Grenache. He said that they were all "monosomething saccharides". Do you know what the term is (and, hey, do you agree with him)?
PS: Great piece on PSs.
Now that I have sold off the high tech service business, I get to have true fun tasting through and characterizing the AVAs of North America for AppellationAmerica.com, my new day job. I recently worked closely with the folks at PS I Love You and in particular with Petite Sirah guru Robert Brittan to tease out the true nature of this awesome New World varietal.
I apologize to those of you bored backwards out of your underpants with the previous technical discussion. Lest you imagine I spend all of my time on such technical matters, please check out my recent posts at Appellation America concerning Petite Sirah.
I recently attended a seminar by UC Davis professor Dr. Andrew Waterhouse who was giving updates of various research projects at the university. Are you aware of the Tannin Assay that has been recently developed? I had posed a question to him about the assay that wasn't answered to my satisfaction so I thought I would direct it to you. (Let me preface by stating that I am just a lowly MW student, so my understanding of the subject is surely more limited than that of a trained winemaker)
An announcement from the normally level-headed Australian Wine Research Institute regarding research into the selection of yeast strains which could less efficiently convert sugar to ethanol, thus allowing fuller grape maturity with less oppressive alcohol. A nice idea, but I'm afraid not practical.
I am one of the owners of a winery in Paso Robles, and we are planning a wine and live music pairing at our tasting room in October. We are family run and many of the members of our family have been in the music business in one way or another for many years (I am a composer myself). Our tasting room is centered around music, with lots of memorabilia, and a built in stage for live performances by jazz acts as well as the "Family Band" - a 6 piece group made up entirely of our family members.
