Not All Wine Is Vegan And Gluten Free Find Out What’s In Your Wine

What’s in your Wine?
Even if you’re not a vegan you may not relish the idea that the wine you are drinking was mixed with gelatin from pigs, cows, and fish bladders, egg whites, and other distasteful animal ingredients, during the wine making process. And for those of you who are lactose or gluten intolerant, you may be concerned that milk protein and wheat gluten may also have been used.

Why is this done?
Many wineries have a formula for making wine that produces a consistent product from year to year that is less dependent on the quality of the grapes they use. The commercial process that is used to create a clear and stable wine or to fix defects is calling “fining”.

Fining
Fining is the operation of adding one or more compounds to wine to bring it into balance and keep it there. Many of these compounds are from animals, gluten and other surprising materials. Although these compounds are filtered out of the wine before it is bottled and sold, there potentially could be some residue in the wine, albeit very minuscule amounts. Here’s are some examples:
* Isinglass (fish bladder) is used to clarify wine.
* Gelatin (pork, cow and fish skin and bones) clarifies wine and removes excess tannins.
* Plant proteins (either green peas or hydrolyzed gluten) is used to clarify wine and remove excess tannins. Pea protein is appropriate for vegan wines.
* Egg albumin is used to clarify wine and remove astringencies in red wine.
* Potassium caseinate (milk protein) improves aromatic defects and treats oxidized wines.
* PVPP (plastic) is used to treat bitterness.
* Bentonite (clay) is used for rapid clarification and to treat protein-unstable wines.Bentonite is appropriate for vegan wines.

Is Fining Necessary?
Our Turtle Vines Pinot Noir is not fined or filtered. No animal products, plastic, or gluten is used in the production of our wine. It is simply not necessary.

To achieve clarity, we “rack” our wine. Racking is the process of letting the wine settle and then siphoning it into another vessel. This is done three times. Occasionally there is a bit of residue at the bottom of our bottles but that doesn’t bother us – it’s better than adding these odd and distasteful compounds listed above.

To balance our tannins, we “cold soak” our destemmed (and about 5% whole-cluster) grapes for five to ten days before fermentation to bring out the beneficial, water soluble skin tannins.
We prevent excess tannins by ending fermentation and pressing the wine before the wine goes completely dry. This controls excess tannins from the grapes seeds by limiting how long they soak in the fermented wine.

Tannins can also seem out of balance if the acidity and alcohol levels are inappropriate. Acid levels are controlled by measuring and adding tartaric acid when necessary. Correct alcohol levels are controlled by picking the grapes when their target sugar content (and flavor) is achieved. With the proper acidity and alcohol levels, fining is not necessary to adjust tannins.

All these methods of carefully balancing tannins prevents having to deal with astringencies and bitterness.

Controlling aromatic defects is much easier to control when you grow and hand-pick your own grapes. At Turtle Vines we examine every grape cluster continually throughout the growing season, discarding any that have mold or mildew or that are not ripe enough to pick. Many large wineries machine-harvest their grapes allowing more bad grapes to end up in the fermentation tank.

The Importance of Organic Grapes
When you go grocery shopping for grapes, many of you buy those that are organically grown. Every year table grapes are listed as one of the Environmental Working Groups “Dirty Dozen“. Their 2014 audits showed that table grape samples has residue of at least 15 pesticides. But when you buy a bottle of wine, most people don’t even think about whether or not the grapes used to make the wine are organic. Conventionally grown wine grapes can be treated with synthetic pesticides, fungicides, insecticides, and fertilizers.

P1020563

According to the California Department of Pesticides Regulation, 25 million pounds of pesticides were applied to conventionally-grown wine grapes in California in 2010. These wine grapes had far more pesticides than table grapes. According to the USDA Pesticide Data Program, there are up to 34 different kinds of pesticide residues found on conventionally-grown grapes! 

Our grapes at Turtle Vines Vineyards are certified organic by the California Certified Organic Farmers Association. It is not only important for our wine to be free of these toxins to protect you, but we did not want ourselves, our workers, our neighbors, or wildlife to be exposed or subjected to these harmful chemicals.

We do not, however, make organic wine. The difference between organic wine and wine made from certified organic grapes is that organic wine does not allow for the addition of sulfur dioxide. Since sulfur dioxide prevents bacterial spoilage, very few wines are made organically as they have a short shelf life. We feel that the majority of benefits to the consumer are obtained by wine being vegan and made from certified organic grapes.

Is Wine Raw?
During fermentation, temperatures rise but generally stay below 85 degrees so, from that standpoint, wine is considered raw. However, some winemakers add sugar during the wine making process to achieve their target alcohol content (not to make the wine sweeter). Unless the sugar used was raw sugar, some would consider this wine not to be raw.

This process of adding sugar to wine is called “chaptalization” and it is generally done in regions that have poor climate and produce grapes with low sugar content. This practice is illegal in Argentina, Australia, Austria, California, Italy, and South Africa. So you can be assured that wines from these regions were not made with sugar. Our California wines have plenty of sunshine and ample sugar content and don’t need this added sugar.

Our 2012 Turtle Vines Pinor Noir is Now Available
If you are interested in purchasing our Pinot Noir, please go to our main page and send me a note for delivery.
Our wine is raw, vegan, unfined, unfiltered, gluten-free, and made with our hand-farmed organic grapes.

The 2012 Pinot is about 80 percent Pommard and 20 percent 667 with a lower alcohol content of 13.0%. This produces a feminine style wine with a taste of ripened strawberry, currant, and cassis. It is a very versatile and food friendly wine which complements almost any dish from pasta to chocolate truffles!

If you mention Foods For Long Life, you will get additional 10% discount. Stock up for the holidays!

2014 Winemaking – What are we doing different?

2014 winemaking

Every year we look at what we did the previous year, if it worked, and what to do differently.

We are very happy with the how the 2013 Pinot turned out based on the sampling we did at bottling.  I’m hoping it progresses to a wonderfully complex wine in the next 9-12 months.

That said, here is what we did last year and changes this year.

Vineyard – Pick when flavors are optimal, usually around 23.5-24 brix.  Mix of Pommard and 667.  2014 – Will ferment/pick Pommard and 667 separately.  Depending of flavors we will bottle 1 to 3 wines.

Fermentation – Inoculate with Assmanhausen yeast after 5 day cold soak.  2014 – 7-10 day cold soak and then allow fermentation to begin for 1-2 days before inoculation to allow complexity from wild yeast.

Oak – 1 Xoaker per gallon of wine.  2014 – 1.33 Xoakers per gallon of wine to add slightly more oak flavor.

 

 

 

Kelvedon (winner of Taste of Tasmania) vs Turtle Vines

Kelvedon

 

When we were in Australia last year, we attending the Taste of Tasmania.  It was a fantastic festival where we got to taste Wines from Tasmania with 40,000 of our newest friends.

Last week we had guests over and decided to see if anyone could tell the difference between the winner of the festival, Kelvedon, and Turtle Vines Pinot.  Interestingly enough, they both had the same flavor profile and only 2 of the 5 people correctly named the wines.

The morale of the story is…we are on the right track with wonderful tasting wine!

One last note of interest.  Almost all of the Australia wines had screw tops and many were made with Flextank technology.

 

 

 

Don’t press wine with a white shirt!

Dirty shirt after press

 

Sometimes you can plan when to press and pick…sometimes it plans for you.  Last week we had a hot spell and the Pinot for Turtle Vines had to be harvested.  This week I thought I had another day of fermenting the Pommard clone…but when I checked at noon on the 9/17…it was ready!  So…I really should have changed my white hemp shirt…but we just started pulling out and cleaning the pressing equipment.   Three hours later we had 96 gallons of pressed juice.  On 9/18 I inoculated with malolactic and will rack on 9/19 and add Xoakers (oak balls).  The 667 clone will get pressed on 9/19.  I think that will go to plan as the temperature had cooled off.

Rain now?

Rain on press

It rained today, September 18th here in Sebastopol.  Not a surprise in most parts of the country, but here it is big news during harvest as the moisture can ruin your crop.  We picked our Pinot last Tuesday/Wednesday/Thursday so that is safe.  Our Sauvignon Blanc is still hanging for another month or so…so I blew them off and sprayed them today.

On Sunday we will pick the seconds from the Pinot and some rogue Merlot to either make a Rose or a low alcohol field blend.  Will have to see how it tastes.

As to the picture…we have the press on the left, 1100 pounds of fermenting Pinot in the middle (clone 667), and 95 gallons of pressed Pinot (clone Pommard) on the right.  I’m really looking forward to how the Pinot’s turn out this year as I let them naturally ferment before inoculating with yeast.  Should add complexity.

California Wine Month, or hug your local winemaker!

Ca wine month

 

California Wine Month in September celebrates one of our signature agricultural products and all that vintners and growers bring to the economy, culture and lifestyle of the Golden State.

Whether you are drinking Russian River Valley Pinot, Napa Cab or White Zinfandel, chances are they were grown and made in California.  So…find what you like and think of us here in California fondly!  Better yet, contact me for some Turtle Vines Pinot Noir.

2014 Harvest at Turtle Vines

2014 crew

September 2nd, 2014 was the start of our harvest activity.  Friends of ours came over and picked 1300 pounds of Pommard (Pinot Noir clone).  The next day, with the help of Bernadino, he and I picked 1100 pounds of 667 (another Pinot Noir clone).  Then on September 4th, Rob’s crew came in and picked the rest of the Pinot Noir that was sold to Horse and Plow, 5100 pounds.   Since my truck and Bill’s trailer only hold 2 tons, I had to make two trips to the winery.

So for those following the last few years…we planted 3130 vines in 2010 and had our first harvest in 2012 of 1400 pounds.  2013 was 5200 pounds and this year was 7500 pounds.  Next year we should be close to a fully mature vineyard and will get close to 10,000 pounds.

By the way…a few months ago I predicted 7780 pounds.  Pretty close when you add in the 100 pounds I will pick for Rose this week and the 200 pounds I dropped due to mildew damage.

Thinning Fruit

P1130062

 

We have about 2 weeks until the nets go up and we have a lot of work to do.  Last week we started thinning some fruit that I didn’t think would ripen in time and we will finish that in a few days.  Next, we will do a second pass to ensure the right amount of leaves have been removed to enhance the flavor of the grapes.  We also will tuck the vines in the wires one more time and spray with potassium bicarbonate to hopefully eliminate the possibility of bunch rot.  Then the nets go up and we stress the vines by reducing the water and hopefully mid September we have almost 4 tons of Pinot noir.

As soon as veraison is complete, I will take a pH reading on the grapes to see if the improvements we made last year helped to make the grapes more acidic.  Let’s hope as it will make wine making much easier.
