More Preparation for Grape Harvest

We had thought that we’d be picking our grapes on Labor Day weekend, but we ended up postponing it just a bit more.  Our total Brix readings were just around 20, and the pH level was around 3.1.  None of the grapes seem to be rotting, shriveling or dropping off, and the netting seems to be very protective.   And there is no rain in the forecast to dilute the grape juice.  So we continue to measure sample grapes for sweetness and acidity, as the sugar levels still go up.

So rather than picking grapes, we spent more time cleaning up the barn where we are planning to ferment the grapes.  We scrubbed one of the stainless steel tanks, which we converted from its former use in a milking parlor to a wine fermenter.  We had to lay it on its side, in order to crawl into it – first to remove a piece of metal that had been welded into the bottom of the tank (a “vortex diverter” for the automated washing system).  This was done with a dremel cutting tool, which was incredibly effective.  Duff took care of the cutting – Tina took are of the scrubbing.   

While the tank was outside the barn, we completely emptied out that section and pressure washed it down.  The press is sitting outside, where it still will need to be cleaned and sanitized as well.   Now we have the tank moved back, and it is sitting upright.  We still need to level it before we can use it, but everything is coming together!

Preparing for Grape Harvest

Pre-harvest preparations started with the onset of veraison (when the grapes begin changing color) about 2 weeks ago.  We are taking periodic samples of grapes, crush them and then measure the pH, Brix and total acid content of the juice.  We are also getting all the equipment ready for harvesting and crushing.  At this point, we are thinking that next weekend may be the ideal time to pick – which would be perfect as most of our family will be visiting for labor day – and laboring they will be 🙂

One of our newest acquisitions is another stainless steel tank – again thanks to Zach and his connections to dairy farmers who are outgrowing their smaller milk tanks.   We had to build a small platform with  a step, so that we can easily look into the tank, clean it and later dump grapes into it.  We’ll try to use it as a fermenter this year, if we get enough grapes.

Netting for Grapes

Last year, we lost of lot of our first potential harvest to a flock of migrating black birds – something we are trying to avoid at all means this year.

We had looked a different types of vineyard netting but they tended to be rather expensive, so for this year, we purchased a 7000 ft long  and 5 ft wide roll of nylon netting used for round hay bales.  Jeff build a “spool box”, which we mounted on the back of the four-wheeler. Jeff also made a box full of small “S” hooks from left over fence wire (while watching a movie). 

We fastened the netting to the end post of the row, and then while Jeff slowly drove the four-wheeler, Lars and Tina unrolled the netting and fastened it with the “S” hooks to the top trellis wire.  It was easy to keep up with the slow speed of the four-wheeler.  We put the netting on both sides of each row, and it took us about 2 hours to finish all 5 rows (200 vines).    We should know in a few weeks if this method is successful – it certainly was easy to put up and not very expensive to do, and we have enough netting left to do twice as much.

Mid August Grapes

The Chambourcin grapes have started to turn colors – they look amazing:
