Day 2 through 15

So I've been a bit lax in my blogging of the experiment due to a family emergency, but I have been progressing according to schedule on the wine front. 

On Days 2 and 3, I left the control batch and Tim batch alone as the instructions indicate.  Fermentation was not foamy, as I usually see with Winexperts kits, but lots of movement and little bubbles.  The Jack batch I had to stir daily, and remove the cheesecloth closure and attach an airlock at the end of Day 2, which I did.

Due to circumstances beyond my control, I did not manage to rack the Tim batch into a carboy on Day 5.  However, Tim mentions in his article regarding the extended time frame that his Day 5 transfer to the secondary is arbitrary, so I decided it would be okay to transfer both the Control batch and the Tim batch to the secondary on Day 7.

On Day 7, the specific gravity (SG) of the control was 0.996, and the Tim batch was 0.997.  High time to get those wines to the secondary!  Interestingly enough, the Tim batch filled up more of its carboy than the control batch.  This leads me to believe that the 23L marking on my primary is incorrect. To compensate for this inconsistency, I've decided to top up all the wines with water, something I don't normally do.  However, Tim Vandergrift, who is involved with the making of the wine kits, says they make them 4% stronger than necessary, so that topping up with water is alright. 

As for the Jack batch, the SG was at 0.998 on Day 7, so I began to add my room temperature one gallon of reserve must at a rate of 1 quart every 15 minutes.

Beyond that, there hasn't been a lot of activity in the experiment.  I will be beginning to degas, stabilize and clear the control batch in a couple days, and 5 days later, begin the same on the Time batch.  For the Jack batch, I don't have to do anything until Day 28.  This means a lot more contact with the gross lees, and the oak is all still in there, although chips usually give up their flavor very quickly.

The Tim and the Control batch visually look the same at this point, but the Jack Keller deviates dramatically.  It's got foam on top, and is a much more murky color--and thus lighter in color--than the other two, which are very inky.  The picture below doesn't quite illustrate the difference, but one wouldn't think they were the same wine started at the same time.

More to report in a couple days as I begin degassing.

Day One: The Experiment Begins

After a marathon 4 hours of wine making, I am finally sitting down to a glass of Winexpert's California Trinity White, and my first blog post.  Ahhhh!  Delightful!

This blog has come about after I proposed an experiment on the incredible forum.  The proposal was to take three identical wine kits, make one exactly according to the instructions, then make the other two according to two other wine kit "schedules":  the first proposed by Tim Vandergrift of Winexperts, and the second espoused by Jack Keller, a Texan of noted wine fame in both grapes and other fruit. Tim's schedule is 90 days until bottling, Jack's is 180. 

The chosen kit is a 6 week kit: Winexpert's Selection International Australian Shiraz. All have had the yeast pitched within 2 hours of each other. The overall idea behind the experiment is to determine which time frame/method actually produces the best wine.  I will have a number of personal tastings, then have an "official" tasting with about 10 people at the two year mark.

Before I continue, I must credit a few folks.  This experiment could not have taken place without the generosity of Tim Vandergrift and Harvest Brewing in Edmonton, Alberta, Canada. To my utter delight, they provided the wine kits for this experiment.  All the lot numbers on the packaging are within about 15 digits, so we are definitely comparing apples to apples.

The various instructions or rather "tweaks" in the case of the two extended schedules have their own differences.  Tim Vandergrift's instructions deviate negligibly from the standard instructions (which, to be fair, he writes) with the exception of time frames.  Jack Keller's set of instructions, however, deviates on many levels.  In an effort to compare the methods as fairly as possible, I am trying to follow each list of instructions to the letter.  For example, on both the "Control" (aka: kit instructions) and the "Tim" batch, I had to add bentonite to the primary.  Since Jack's instructions do not call for the addition of any bentonite until Day 29, I did not add it at the time of yeast pitching.  Additionally, both "Tim" and "Control" batches are fermented in a primary fermenter, whereas Jack's instructions have one ferment in a carboy with one gallon held in reserve until vigorous fermentation subsides. 

A few personal notes:
  • Holy oak Batman!  Each kit contained 60 grams of toasted, and 60 grams of "premium" (read: untoasted) oak. I've not personally seen this much oak in a kit, but I'm interested.  I like oak.
  • Jack Keller's schedule is really fussy and is much more involved than standard kit instructions.  His directions were 5 pages (!) long after printing.  Having said that, if it makes a much better wine, I'm not complaining.  Plus I've never fermented in a carboy, only a plastic "primary fermenter" so that's an immediate interest factor.
  • One of my main concerns is making sure everything is degassed properly.  That can affect many perceptions in wine.  However, I'm also determined to play by the instructions, so I'm not using my brake bleeder in this experiment. If anyone would like to come over and help stir "vigorously", let me know.
  • Another concern is to keep each wine distinguished from one another.  Careful labelling of all the additives, primaries, carboys, etc, will definitely be necessary.
  • I will filter each wine. As a formal tasting will take place after a suitable amount of time, I do not want appearance to be affecting the tasting panel's perception.
