Cleaning vs. Sanitizing in Winemaking

What is the difference between Cleaning vs. Sanitizing?

This is a discussion we have with customers constantly. Cleaning your equipment means that you have removed all of the visible dirt and residue on your equipment. Sanitizing means you have treated your equipment with a chemical solution that will eliminate, or prevent the growth of spoilage organisms. You MUST clean your equipment before sanitizing the equipment, since you cannot properly sanitize equipment with visible residue on it.

Below is a video from our online classes – WinemakingInstructions.com that talks about and shows you step by step how to clean and sanitize your equipment.

How to Make Syrah Wine from Chilean Wine Grapes

Chilean Syrah from Colchagua Valley has received high praise from publications like Wine Enthusiast, earning 93+pts. It’s a wine variety that is often overlooked from Chile and is a wine worth making this season. Chilean Syrah boasts flavors of plum, wild berry, and earth aromas. I highly suggest introducing this wine to oak barrels or an oak infusion. The medium acidity and powerful aromas are complemented by the French Oak flavor profile.

Yeast Suggestion: CSM yeast

Oak Suggestion: French oak barrels or chips

Wine Flavor Profile: Bold, medium tannins, blackberry, plum, wild berry, leather, smoke, chocolate, and oak

How to Make Syrah Wine from Chilean Wine Grapes:

  1. Crush Syrah grapes into a sanitized bin or tub. (Each 18lb crate will make 1.25 gals of finished wine).
  2. Apply 50ppm of Potassium Metabisulfite and stir well. Allow to sit for 8-12 hours.
  3. Apply .5ml of Color Pro Pectic enzyme per box diluted into a 10% solution with water to the must and stir. Allow to sit for another 8-12 hours.
  4. Mix Booster Rouge, FT Rouge, and Opti-Red, with spring water until it is the consistency of pancake batter and pour over top of crushed grapes. Mix in well.
  5. Add rehydrate CSM yeast (1g/gal) with Go Ferm rehydration nutrient and warm water. Allow to sit for 15 minutes and pour over top of crushed grapes.
  6. Punch down grapes 3 times per day throughout the duration of fermentation and monitor temperature and Brix levels daily. Use a hydrometer to test sugar content in a strained juice sample. Make sure the temperature does not exceed 85F.
  7. One day after adding the yeast, add Fermaid O, mixed with spring water into the pancake batter style slurry. Dump into grapes during a punch down.
  8. After the depletion of 1/3 of the Brix (when the Brix level is between 16-11), add Fermaid O that is mixed with spring water into the pancake batter style slurry. Dump into to grapes at a punch down.
  9. Add Malo-lactic bacteria the same day as the Fermaid K. If you are using liquid cultures, just pour over the grape must and mix. If you use the dry cultures, rehydrate them in warm spring water according to their specific directions, utilizing any rehydration nutrients recommended.
  10. When the Brix have dropped below zero, press the wine into a sanitized tank, carboy, or demijohn. Make sure the vessel is topped up all the way to the top of the neck and sealed properly with a bung and airlock.
  11. Rack after 48 hours and then again in a week. Allow MLF to complete before adding sulfites.
  12. Allow the wine to age and rack it every 2 months and add sulfites when racking.
  13. Add oak infusion after 2nd or 3rd racking. Taste test along the way until the oak profile is where you want it to be.

What is Bud Break?

Happy first day of Spring Winemakers!

Our California grapes are starting to go through bud break.

Here is a nice view of our Cry Baby Thompson Seedless and Grenache grapes “waking up” 🍇

What is Bud Break?

Bud break is the start of the grape vine’s annual cycle. It is a relaxing time in the vine’s life as long as they don’t experience any intense weather occurrences, such as frost. Frost can kill the buds or delay their growth.

Product Spotlight: CSM Yeast

csm yeast

Product Spotlight: CSM Yeast

CSM yeast was derived from Bordeaux and helps create a vibrant aromatic profile. CSM aids in adding complexity to the palate and pairs well with malolactic fermentation.

Why you want to use it:

It’s the perfect yeast for the Chilean fruit. It reduces vegetal aromas, adds complexity, stabilizes color, and helps increase the aromatic profiles of berries and spices.

Use Tips:

Fermentation starts quickly with this yeast. Be prepared to see Brix drop 24 hours after inoculation. It can stand up 14% ABV and can handle temperatures from 59–90°F. However, I highly suggest keeping your fermentation temps lower than 75°F. Once you hit 80°F you lose aromas and “burn off” flavors. Keeping your wine between 59–75°F during fermentation is a best practice.

You also want to use nutrients when using CSM; nutrients such as Fermaid-O and Fermaid-K. CSM tends to produce H2S (rotten egg smell) if there aren’t enough nutrients during fermentation.

Avoid cold shocking the yeast at inoculation. You’ll want to get the must and the yeast starter within a few degrees of each other before pitching the yeast starter. But without temperatures falling lower than 55°F. Temps below 55°F could stall fermentation and/or kill the yeast.

Goes best with:

CSM was cultivated to help ferment Cabernet Sauvignon, Cabernet Franc, Grenache, Merlot, Sangiovese, Petit Verdot. However, we have seen it used on Carmenere, Malbec, and Syrah from Chile with great results.

Dosage:

6gm/gals

Flavor Profile:

Cherry pit, raspberry, blackberry, spice, violet, bark, and sweet pepper

Montepulciano 2020 By Joseph A. Picone, DMD

Montepulciano 2020 By Joseph A. Picone, DMD

I had the pleasure to obtain 10 (36lbs) cases of Montepulciano grapes from Musto Grapes (Frank Musto) on October 10, 2020. Making wine using the many varieties of first class Musto sourced grapes has been an Annual fall event for the Picone family and our friends for the past 30 years or so. Over the years, I have made Cabernet Sauvignon, Merlot, Old Vine Zinfandel, Sangiovese, Malbec, Reisling, Chardonnay, Sauvignon Blanc, Moscato, and White Zinfandel to name a few. Each having their own unique qualities to enjoy. Frank and his crew are great in providing all the resources and guidance needed for the first-time wine maker all the way to the seasoned-pro. I was fortunate to have taken a one semester class years ago at Naugatuck Community College on Wine Making given by Bob Herold which together with Frank’s support team has allowed me to create some delicious wines over the years.

I would like to share my experience with you on making this year’s Montepulciano 2020.

The grapes were outstanding. The Brix reading on the refractometer was 25. The clusters were full and the berries were a beautiful deep purple. The boxes were well packed with few if any leaves. We crushed the 360lbs of grapes and immediately added some potassium metabisulphite to kill any wild yeasts. My crusher is also a destemmer, so all the stems were separated from the must during this process. The pH of the must started at 3.70 which wasn’t surprising due to the high Brix reading. I added an appropriate amount of Tartaric acid to bring the pH to a more desirable 3.41 the day of crush. 25 ml of Color Pro enzyme was added at this time as well.

At approximately 24 hours post crush, the Must was inoculated with 35 grams of yeast BM 4X4 in a solution containing GoFerm yeast nutrient. The temperature of the Must at the time of inoculation was 60 degrees F. The yeast solution was well constituted throughout the must. Periodic punching down of the “cap’ was done every 6-8 hours throughout the primary fermentation time.

At 48 hours post crush, the Must temp was 66 degrees F at the Brix reading was 23.5. Fermaid O was added.

At 72 hours post crush, the Must temp was 75 degrees F and the Brix reading was 20. Fermaid K was added.

At 96 hours post crush, the Must temp was 82 degrees F and the Brix reading was 16. I added oak chips to the vat.

At 120 hours post crush, the Must temp was 78 degrees F and the Brix reading was 8.

At 144 hours post crush, the Must temp was 72 degrees F and the Brix reading was 4. 0.9mg of Malolactic culture VP41 was added to the Must and thoroughly mixed in.

At 168 hours(7 days) post crush, the Must temp was 70 degrees F and the Brix reading was 3. The Must and remnant skins were carefully pressed using a bladder press. The raw yield was approximately 27.5 gallons. The Must was placed in cleaned and sanitized demijohns utilizing airlocks to allow CO2 to escape while fermentation progresses, albeit very slowly. The residual skins were heavily consumed during the fermentation leaving behind very little structure. The color extraction was excellent and provided a deep rich purple wine. More Oak chips were added to each of the glass carboys/demijohns.

The slow fermentation in the demijohns went uneventfully and at 2 months, careful racking was accomplished and an appropriate amount of Potassium Metabisulphite was added to help kill off any more yeast cells(30ppm).

At 6 months post pressing, another racking was accomplished without the addition of any sulphites.

At 9 months, I have just begun bottling and I am very pleased with the wine. It is a crystal clear, deep purple, medium to full body, somewhat fruity flavored wine. I expect it to pair well most any dish but have enjoyed it with pasta, pork, veal, and chicken thus far.

Sincerely,

Joseph A. Picone, DMD

King’s River Ranch Harvest Update

King’s River Ranch – 2020 Harvest

kings river ranch-wine grapes-musto wine grape-winemaking-home winemaking-how to make wine-winemaking instructions-grapes for winemaking

Nestled in Sanger, CA, southeast of Fresno, and on the way to Squaw Valley, Tahoe and the Sierra Foothills; is 40 acres of meticulously manicured vineyards known as King’s River Ranch. This season we are hearing that harvest is about 2 weeks earlier than last season coming out of King’s River. The grapes are developing well and they are having some great temperature swings in the vineyard.

The vineyard is made up of white ash & sandy loam soil. The vineyard has been in existence since 1954 and the family has grown everything from grapes for wine, raisins, peaches, plums, and apricots on this little piece of paradise. However, they ultimately decided to focus on what they love most – boutique style wines. The vineyard was planted in 2012 and produces Cabernet Sauvignon (Clone 337), Petite Sirah, Syrah, Barbera, Cabernet Franc, Tempranillo, Merlot, Sangiovese, Primitivo, Albariño, Muscat, Teroldego, and Pinot Noir. Each block is diligently managed. They thin leaves, drop fruit to secure intense flavors, and drip irrigate as to not over-water the vines.

Veraison in the vineyard and how it affects winemaking

Currently our grapes are going through veraison in California. Veraison occurs when the berry transitions into the ripening stage. From now forward the berry will increase in sugar concentration until it is harvested at the desired brix level. Grapes for sparkling wine or champagne are harvested around 17 brix and grapes for still wine are harvested around 25 brix. The brix level will determine the alcohol level in the wine. For example, a grape picked around 25 brix should create a 12.5% alch by volume wine.

Harvest will be here before we know it! It’s to time start getting organized. Click HERE to see our upcoming events and classes that will help you get ready for harvest.

2018 Chilean Harvest Update

This year’s growing season should produce some intense and complex wines!

We are very excited and fortunate to be sourcing our Chilean grapes and juices from the “Heart of the Chilean Wine Industry” known as the Curico Valley.  Curico has been a wine grape growing region since the 1800s. With its fertile soil, microclimates, and the ability to grow over 30 different wine grape varieties, it’s no wonder this prestigious region is considered the heart of the wine industry.

Soil Content: Sand, clay, decomposed granite, and volcanic-alluvial.

The second region we will be sourcing from is the Colchagua Valley. The Colchagua Valley is known for growing bold red wines, such as Carménère, Cabernet Sauvignon, Cabernet Franc, and Syrah. It has a mediterranean climate and is located along the southern end of the Rapel Valley. This topography creates a climate that receives around 23.3 inches of rainfall per year and little to no rainfall during their summer months. This helps keep the grapes safe close to harvest and ensures that the grapes are fighting for water therefore creating a more intense fruit.

 Soil Content: Sand, decomposed granite, and clay

This year’s harvest has gotten off to a great start. The white grapes are coming off the vine and will be in transit soon. Our early red grapes such as Pinot Noir and Merlot will start harvesting around March 30th.

Arrival Dates: White grapes should arrive around the last week in April and the red grapes should start to arrive around the first week in May. Get your crushers ready!

Grapes Still Available: Carmenere, Chardonnay, Pinot Grigio, Sauvignon Blanc, and Viognier

Sold Out: Cabernet Sauvignon, Cabernet Franc, Malbec, Merlot, Petite Verdot, Pinot Noir, and Syrah

Juices Available: Carmenere, Cabernet Sauvignon, Cabernet Franc, Cabernet/Merlot Blend, Malbec, Merlot, Petite Verdot, Pinot Noir, Syrah, Chardonnay, Pinot Grigio, Sauvignon Blanc, and Viognier

Fresco Juices Available: Cabernet Sauvignon, Carmenere, Merlot, Malbec, Chardonnay, Sauvignon Blanc, Viognier, Chardonnay/Semillon Blend

IMG_9027

  • Sauvignon Blanc – For the SB the most important thing is the yeast that express the thiols aromas. Try VIN13 to bring out such thiol aromas like tropical fruits.
  • Carmenere & Merlot – Try a yeast that expresses the black fruits like CSM
  • Cabernet Sauvignon –You want the fruit and earthiness to shine. Try D254, BM4X4, or CSM. Maybe think about blending yeasts for more complexity!
  • Pinot noir – RC 212 is one of the best yeasts for Pinot Noir.

Manuela’s Favorite Blend:  Merlot-Carmenere

Why does Sauvignon Blanc wine taste so good from Chile? (According to Manuela)

  • “The different temperature between day and night is very important to the aroma expression, we have that kind of climate in our Valley (Curicó) so our SB is very aromatic and with a good acidity. We ferment at 58-50ºF to preserve the aromas.”
