September Brix Readings - Part 2

The Birds are coming! Pretty much every row we did not net became food for the Birds - they are very efficient pickers too. Luckily they did leave enough fruit to allow me to do more Brix readings. Brix were measured by testing 3 to 4 grapes at various locations on each row. So as of September 19:


WHITES

Siegerrebbe: 20.5 

Muscat harvested  Sept. 24 at 20.5 Brix

L'Acadia Blanc: 21.5

Osceolo Muscat: 19.5

Epicure: 19

Petit Milo: 21

48-05-49: 20.5

Leon Millot harvested Sept. 24 at 21.5 Brix

RED

48-05-83: 17.5

Labelle: 21

Baco Noir: 16

Zweigelt: 20

Leon Millot: 20.5

Pinot Noir:17.5

Regent: 18




Let the wine making begin! A few members selected varieties to make wine from and harvest on L'Acadia Blanc (46lbs), Petiti Milot (34lbs), Leon Millot (108 lbs, with a bit of Pinot Noir) and Osceolo Muscat (125 lbs) was done on Sept. 24. 

48-05-83 and Baco Noir are also slated for the carboy, but they need a bit more time on the vine to ripen up still.

Pretty low yield on the L'Acadia as the bunches were very loose and not very populated. This is likely from poor weather in late spring during bloom. Hopefully it will improve next year. The yield on the Petit Milo was very good, but as it was not netted, there was not much fruit left by the time it was harvested. The two types were mixed into one batch of wine and with final Brix of 23 it should make a very nice wine.

September Brix readings

As of September 4 most of the hanging fruit is looking nice.  Varieties that members are hoping to make wine from have al been covered with bird and insect netting. good job all! 

A quick walk through with the refractometer provided the following sugar content numbers.  Brix were measured by testing 3 to 4 grapes at various locations on each row. 2015 measurements were gathered on September 7 and are shown in brackets. A few are progressing very nicely. but we will need a pretty good September to get the other numbers up.

Summer Update - Reds

As mentioned in the previous blog, an update on the Red status is below. The data for this post is from August 14 2016 so I am a bit slow in posting. I will do an update soon with some Brix numbers now that we are into September.

Blattner

48-05-83: small-med berries in fairly loose bunches.  No signs of powdery mildew (PM) or other issues. Veraison is present on most vines (about 70%)

Labelle: Small berries in loose bunches.  About 80% of the fruit is showing veraison.  The vines look good, no signs of PM and not overly vigorous.

Cab Libra: This was an under performing vine that was removed in the Spring of 2016.

Remaining Varieties

Baco Noir: small-medium berries in loose bunches.   It still struggles a bit with low vigor. No PM visible and vines look healthy. About 80% of the fruit is showing veraison.

Zweigelt

Zweigelt: medium sized berries in tight(ish) bunches.  About 60% have achieved veraison.  Overall vines look healthy but low vigour. No PM visible, but many leaves have turned bright red. 

Leon Millot: Small berries and semi-tight bunches.  100% have achieved veraison.  Note this was achieved by August 7.

Leon Millot

Pinot Noir: Small berries in tight bunches.  No PM visible and vines look healthy. About 50% are showing veraison.

Regent: Small-medium berries in loose bunches. No PM visible and vines look healthy. About 50% are showing veraison.

Baltica: This was an under performing vine that was removed in the Spring of 2016.

Marquette: This was an under performing vine that was removed in the Spring of 2016.

Summer Updates - Whites

August is nearly half over now and the vines are quite happy with recent wave of sunshine and heat. Our spring was really great, but the early part of the summer was sadly quite wet and cooler than normal. as a result the vine growth has fallen back to about the same as last year.

Fruit Set: It appears that vines that had bloom quite early were better of this year as vines with later bloom did not have great fruit set. I suspect this is a result of cooler temperatures and heavy rains that may have  impacted the pollination process.

Powdery Mildew (PM): Despite a fairly aggressive and consistent spray program, PM still reared its ugly head.  We have trimmed all the fruit from Chardonnay, Auxerrois, Mad Angie and Mad Sylvaner. Siegerrebe is looking like it has some impact as well and may need some culling shortly

Some PM on the fruit

Blattner

Petit Milo

Petit Milo: small-med berries in fairly tight bunches.  No signs of powdery mildew (PM) or other issues. Very nice growth and canopy seems to manage itself. As of August 14, veraison has started on most fruit.

Vine Bloom and Fruit Set

June is nearly over and it has been a very wet and cool month.  This is not unusual for June, just a stark contrast to some of the early weather we have had.

Bloom on Chardonnay

The vineyard has continued to grow despite the weather and we are still a bit ahead of previous years. All varieties have completed bloom and moved into fruit set.

So what is bloom and fruit set?
The grape flower does not have conspicuous petals like other plants. Instead, the petals are fused into a green structure commonly referred to as the cap. The cap encloses the reproductive organs and other tissues within the flower. A flower consists of a single pistil (female organ) and five stamen, each tipped with an anther (male organ).  The cap separates from the base of the flower, becomes dislodged and usually falls off, exposing the pistil and anthers (bloom phase). The anthers may release their pollen either before or after cap fall. Pollen grains randomly land upon the the pistil, allowing pollination. The  subsequent growth of berries is called fruit set. 

Whites:
Siegerrebbe, Chardonnay, Madelein Sylvaner and Angevine:
A bit behind other whites.  Full bloom has occurred with partial fruit set beginning.

L'Acadia Blanc, Osceolo Muscat, Auxerrois, Petit Milo, Epicure and 48-05-49: 
Full bloom has come and gone and full fruit set is in place.

A bit behind other reds.  Full bloom has occurred with partial fruit set beginning.

Labelle, Baco Noir, Leon Millot:
Full bloom has come and gone and full fruit set is in place.

As always, comments and feedback is encouraged.  Hopefully we get some sustained sunshine and heat and get our fruit on!

June 2016 Update

As we move in to the heat off summer, the vineyard continues to impress this year.  From my last post we were roughly 3 weeks ahead of previous years and the trend has been maintained.  By May 1 100 % of all varieties had active growth.  By June 1 a few vines (Osceolo muscat, Leon Millot) are already at bloom. Fruit set is not far off.


We have also been maintaining the spray program as well as the weed control and the efforts are paying off as the vineyard looks quite established.

We had a pretty wet May and with the heat of June, things really took off.  Volunteers have been busy suckering, pruning and tucking vines into the trellis wires and doing weed control.  Keeping on top of the vines and weeds is critical this year as we really want to have the best representation of our fruit.



We will be doing a fundraising event concession in Burton during the Burton City Daze on June 18. The concession will be open for lunch between 11AM and 2PM so come on out to visit Burton, partake in some activities (Burton relay Race, Kootenay Sufferfest etc) and have some fun.

Hope to see you all there!

Spring Update 2016

This spring we made the difficult decision to cull a few of the under performing varieties.  We felt that after 3 years these vines were far behind where they should be and without significant more work to pinpoint the reasons (soil, nutrients, climate etc.) things would not change.

So goodbye to Marquette, Baltica and Cab Libre.  In addition we also removed Ortega.  Ortega performed well, but its susceptibility to powdery mildew proved  to difficult to control and always ended up spreading the mildew to the neighbouring vines.  While it is sad to pull up living vines, this is what he research was for.

With a down turn in our volunteer pool the last while, we also decided to shorten some rows to make it more manageable.  We kept five full length rows (Siegerrbbe, L'Acaida Blanc, Osceolo Muscat, 48-05-83, Leon Millot) and shortened the rest to about 15 vines.

On the good new front - we are way ahead of last year at this point. As of April 21 the vines showed the following progress:

Osceolo Muscat on April 21

Whites:

Osceolo Muscat, Chardonnay, L'Acadia Blanc, Siegerrebe, Madeleine Angevine, Petit Milo: all had achieved 100% bud burst with 1" growth already. Osceolo and Petit had closer to 2" shoots.

Auxerrois, Madeleine Sylvaner; , 48-05-49: These were ranging from bud swell to advanced bud swell.

Epicure: Still in the bud swell range.

Labelle on April 21

Reds:

Labelle, Baco Noir, Leon Millot,  Zweigelt:  All had achieved 100% bud burst with 1" growth already. Baco had closer to 2" shoots.

Regent, 48-05-83, Pinot Noir mainly in the advanced bud swell stage.  pinot are closer to advanced bud swell

Weed control

At this point last year we were still in bud swell only, as it was in early May before we had any bud burst.  It is interesting to note that the order the vines are progressing at is the same, Epicure and Regent for example are always later than other vines.


You can see our weed control has already started for this year.  Our Vinegar solution proved effective and the hope is to hit the weeds a few time early in the season and then cover with a mulch to control them.  this would hopefully reduce the amount of weeding and weed whacking we had to do last year.
