It seems some members of the press have, unlike 2010, already grabbed a hold of the 2011 Willamette Valley vintage and are attempting to run it into the ground. GDD are tracking about a week behind 2010, which was itself a difficult year to get phenolic ripeness of any type. There were a few properties that were able to ripen fruit, but the overwhelming majority came in under-ripe and needed substantial chaptalization and subsequent chalking out of the high acidity, mostly well before ML fermentation began. Make sure you read the comments to this article and take their opinions with a grain of salt. While they seem to remain optimistic as one of the most challenging vintages in Oregon's history looms, they are also producers who live and die by press like this. I'd love to take the advice of a "farmer in the field," unless that farmer had as much skin in the game as these do. But, we'll see how this rounds out when fruit begins arriving this/next week.

Full disclosure: Highest brix and pH we've seen so far on any Willamette pinot noir property: 20.1 brix, 3.05...and that was yesterday. For reference, in 2008, fruit began to come in at 24-25 brix and around a pH of 3.5 in the last part of September. God have mercy on our souls.

Hi Thread. I'm relatively new to wine and I'm still trying to get my footing on being able to differentiate between different types and varieties. So far I've enjoyed red wines like cabernet, though a lot of wines still are mainly hot or quite acid. I remember beer being similar, though more tasting like piss and ear wax, but the revelation of being able to taste the hops and malts came from after brewing up a batch and smelling/tasting the hops by itself. After that beer tastes amazing. So I've decided to so something similar with wine by making some.

My dad used to be an avid beer/wine maker many years ago, so I've inherited (stolen) his brewing equipment in the cellar and cleaned it up. I started looking online at different wine making kits or whatever, but soon discovered that it was grape harvesting season soon so I decided to buy some grapes instead. I've also read this 150 page free ebook online cover to cover, describing the different techniques and procedures for making the wine, covering the many sugars and acids in grapes and how they affect taste/stability of the wine, the chemistry of pH, free SO2 and how they protect wines, processing and fining, primary and secondary ML fermentation, and a bunch of other stuff. Feeling well-armed with my new found knowledge, I decided to buy 3x 36 lb cases of petite sirah and 4x cases of cabernet sav. I also got a (I think) decent pH meter and cheap materials to build a free SO2 AO test apparatus. I bought the grapes this past Sunday.

When I tested the grapes before fermentation, the petite sirah came out to: pH 3.4, brix ~19.5, TA 0.58%, and the cab sav came to pH 3.59, brix 21.5, TA 0.48%. I put in some K metabisulfite and pitched the yeast the next day and let her rip.

Now some questions. (I hope it's ok to ask wine making questions here...I've read the entire last thread and there weren't any but I devoured all of the wine making posts) Is it bad that I didn't adjust the must before initiating primary fermentation? I've read to adjust it before pitching yeast, but I've also read people adding sugar a little at a time throughout fermentation if the brix level is a little low. Same question applies for adding tartaric acid after fermentation? It seems like it would be better to adjust it to taste after the grapes have fermented. I added 500 grams of dissolved sugar to the petite sirah today to bring it up ~ 1%. I know that the alcohol will be a little low but that's ok I think, wine in general seems too hot for my palate atm. We'll see how it goes I guess. So far the whole process has been a blast!

The grapes are fermenting in my bedroom atm since it's somewhat temperature controlled. It's been holding steady at ~75F. Also my room smells amazing. Hearing the grapes fizz at night makes me smile.

The optimal time to make sugar additions if you don't do them en masse prior to inoculation is in equally spaced intervals during the steepest part of the fermentation curve (during which the second third of the sugar is consumed in fermentation). In fact, there have been some recent papers suggesting that lengthening this phase of fermentation actually encourages glycerol production. That said, adding it too late could potentially leave you with some unwanted residual sugar once the yeast begin to shut down. So, I would recommend adding early and often.

I'm assuming you are planning on innoculating the batch with an ML culture once primary fermentation is done(unless you have already done so). If you have to add more tartaric (I personally wouldn't this with these varietals at that pH/TA), add it between the end of primary and the start of secondary. Alternatively, you could add the tartaric acid just prior to bottling, but it won't "integrate" as well as if you adjusted it prior to primary. I would just recommend against it in general with the fruit that you currently have. Be sure keep the pH > 3.5 so that the ML ferment doesn't struggle. You'll also want to wait to add any significant amount of KMB until after ML is complete. Otherwise, good luck. Also, for home winemaking purposes, I would recommend against any extended maceration. There have been several recent articles in the industry journal that basically show the net effect as negligible (across different [EtOH]). In the future, any improvements you would like to see in phenolic extraction and color stability should be made via cold-soaking, and even that should probably never exceed 3 weeks.

Also, as a rule of thumb, the general conversion factor for brix to %abv is roughly .55. I've seen yeasts produce more and less EtOH, but this is close enough. So figure that, with your current brix, you'll get 10.7% and 11.8% abv, respectively.

I tried a couple different Texas vineyards around here in the Hill Country. None of them were particularly amazing. I suppose I'd better give them a few more decades to refine their techniques or something, I just really like supporting local businesses.

I worked there for 3 years as a winemaker in the Hill Country. Texas wine has about as much of a chance to compete nationally as Missouri, Virginia, or other states where you shouldn't grow winegrapes. As far as contemporary winemaking goes, Texas has been making wine about as long as Oregon or Washington, but can't seem to figure out issues like disease control or varietal/rootstock optimization.

As a general rule, you'll find that the average Texas winery lacks the level of talent that wineries in the larger wine producing states possess, which compounds issues with producing wine with sub-par fruit. That said, they all aren't terrible producers; Becker, Grape Creek, and the high-tier Llano Estacado all have great wines for where they are made. Just manage your expectations and understand that you'll be paying a premium for a local product and not superior quality.

My teeth stain really bad when I drink red wine. Less so if it's something light like Pinot Noir, but if am tasting a line-up of cabs or something, by the end of the tasting my teeth look horrible. I am usually able to wipe a good amount of it off with a wet paper towel. I agree though, it's annoying.

My lips also stain easily. If I get really drunk on red wine my lip skin will stain so deeply it beds in like a tattoo. For the next day or two until that skin dies and goes away I have obvious red wine stains on my lips like I have been sipping wine all day. Kind of sucks when you have to go to work looking like that.

A dilute solution of Oxiclean for the lips and some kind of peroxide based whitening toothpaste should clear that right up. I use oxiclean for my hands during harvest. They turn black otherwise.
