The Winemaker’s Think Tank: Vol 7 – Grape Yield

Wine expert testing wine silhouette image

What’s the Winemaker’s Think Tank? 

Every Thursday we will post about a few frequently asked questions that our winemaker has answered. If you have a winemaking question you would like to have answered, please email us at support@juicegrape.com and we will try to get into next week’s post. Cheers! :)

When it comes to making wine, often there is nothing more exhilarating than sampling the fresh grapes as they come in and selecting the varietals that will best suit your individual winemaking needs. Once you have selected the varietals that you would like to make that season, the most often the next question is “How many grapes will I need to make my desired amount of wine?”. The answer changes slightly depending on the origin of the grapes. South American producers fill their crates with 18lbs of grapes. This typically requires the winemaker to purchase 4 crates (18lbs each) to yield 5 gallons of wine. The same formula roughly applies to South African grapes as well, with their grapes being packed 20lbs per crate. Obviously this will yield the winemaker a bit more juice, but the overall formula is applicable.

Fall harvest from the northern hemisphere gives us slightly different guidelines to follow for estimating yield. North American producers have larger crates, packed 36lbs/crate. On average, each crate yields 2.5 gallons of juice, the winemaker needing two crates per five gallons of desired wine. Seasonal growing conditions apply to the yield as well, rainfall having the most profound effect upon juice yield. Also, premium growing areas where the grapevines grow under stressed conditions, resulting in premium fruit will yield significantly less juice than grapes grown in irrigated fields. We suggest purchasing one additional crate per desired 5 gallons of finished product. The two crates per five gallon rule is a safe assumption when estimating juice yield, as it is more of a conservative estimate of juice yield. We often hear reports of a higher yield rate for certain west coast varietals. Berry size will affect the yield of juice as well. Pinot Noir and Grenache berries are significantly larger than Cabernet Sauvignon and Petit Syrah berries, often yielding up to 10% more juice. While a certain level of experience and research can aid in the estimated juice yield from your grapes, the basic rule of 4 crates per 5 gallons for South American/African produce and 2 crates per 5 gallons for North American produce is an easy means of determining how much produce you will need.

We hope this information helps with your winemaking. If you have any follow up questions or winemaking questions in general, please email us at support@juicegrape.com.

Paso Robles Update

paso cab

Paso Robles is one of California’s emerging AVA’s. It has grown from a sleepy town to a high end wine growing and wine producing region. Paso Robles Wine Country is ideally located along California’s Central Coast, conveniently between San Francisco and Los Angeles. Over the past decade the number of wineries has more than tripled, and Paso Robles is now home to nearly 200 wineries. Winemaking on the Central Coast began when the Franciscan Friars traveled through California establishing Missions. The Missionaries started planting grapes in 1790. You can still see these vines growing today. Since the original plantings of the Missionaries, Paso Robles has become a top destination for farmers to plant grapes. Many famous people have planted vineyards and started wineries in this region. For example, Ignace Paderewski, the Polish pianist purchased 2,000 acres in the 1920’s. He planted Petite Sirah and Zinfandel and eventually opened York Mountain Winery; which is still in existence today.

Paso Robles is comprised of 26,000 acres of wine grapes. It is one of the fastest growing wine regions in California and on the Central Coast. It has a diverse topography. There are rivers, roiling hills, flat lands, and mountains. The soil is comprised of bedrock, weather granite, marine sedimentary rocks, and volcanic rocks. Because of the many different soil components one vineyard block could contain several different soil types.

 

In terms of grapes, Paso Robles is known for growing Zinfandel, but has gained recognition for Bordeaux and Rhone varieties. The AVA likes to produce non-traditional blends. It is a valley that doesn’t follow the rules and expectations of tradition winemaking. The winemakers of Paso Robles like to make their own rules.

Musto Wine Grape Company will be offering the following wine grapes from Paso Robles: Cabernet Sauvignon, Cabernet Franc, Merlot, Pinot Noir, Petite Sirah, Syrah, Zinfandel, and Old Vine Zinfandel.

  • The Paso Petite Sirah resides on the East side of Paso Robles. Days are hot for a longer period of time than the west side but the temperature will drop down to 50 degrees and below at night. The grapes ripen while maturing slowly to produce  a wine with aromas of blueberry, raspberry, and black coffee.  The wines from this area show deep color, are full bodied, and have a smooth tannic structure.
  • The Paso Merlot, and Syrah are sourced from Tolosa Winery from their “Meeker Vineyard” blocks.  The Syrah is the Shenandoah Clone and on 5BB rootstock. Finally, the Merlot is Clone 3 and on 5BB rootstock.
  • The Paso Zinfandel and Old Vine Zinfandel are sourced from the Steinbeck Vineyard. The Zinfandel resides on east-west rolling hills. The soils are calcareous and are farmed by a multiple generation vintner.
  • The Pinot Noir is sourced from Opolo Vineyards of Paso Robles. The Pinot Noir vineyards are located in the Willow Creek AVA. This region cools down earlier than the East side. The area is known for getting any varietal ripe and mature. The soil is very calcareous which produces a very elegant Pinot Noir.
  • The Cabernet is sourced from Parrish Templeton Vineyards. These grapes go to wineries such as Opolo and Justin. It is located in the “Pomar Junction” area of the Templeton gap. The soil consists of clay topsoil, over-lying a fractured calcareous base. This vineyard was created to produce high end Cabernet.
  • Varieties from Paso Robles:
    • Cabernet Suavignon
    • Merlot
    • Pinot Noir
    • Petite Sirah
    • Syrah
    • Zinfandel
    • Old Vine Zinfandel

We are currently taking orders for ALL Paso Robles grapes. The Pinot Noir will be arriving on 9/9/16. Make sure to secure your grapes today!

A taste of Italy from Lanza Musto Vineyards

{Lanza-Musto Brunello Clone Sangiovese going through veraison}

Can’t make it to Tuscany this year? Don’t worry, you can make some fabulous Sangiovese right here in the US! Lanza-Musto Vineyards has been producing Brunello Clone Sangiovese for the past 4 vintages. One of the big reasons we planted this varietal is because the valley provides hot days and cool nights. The temperature can swing over 50 degrees depending on the time of year. Sangiovese eats this type of weather up! This high producing varietal soaks up the sun and enjoys the break under the cool night air.

When producing Sangiovese wines keep in mind that even though it is a bold tasting wine, it can easily be overtaken by oak infusions. Both the Musto Wine Grape Co. and Winemaker Magazine suggest using small amounts of oak or aging your wine in neutral barrels. The oak flavoring can overpower the wine and you will lose the delicate acidity and  bright cherry notes that Sangiovese is known for. Also, blending in a little LMV Barbera or Merlot can help give it a little extra structure and complexity. 

Since Sangiovese originated in Italy, the wines pair famously with anything tomatobased. We suggest pasta, pizza, or any meat dishes that have a tomato sauce. Frank Musto from Musto Wine Grape Co., LLC. personally enjoys his Sangiovese with Pepe’s Pizza from New Haven, CT or a great Chicken Marsala.

Sangiovese is one of the hottest up and coming varietals being produced in the United States. Make sure to secure your order of Brunello Clone Sangiovese for Fall 2016. You will not be disappointed!

Cheers and Happy Winemaking!

Chilean Harvest Update: Arrival Dates

Chilean Harvest Update: Arrival Dates

The wines of Chile –  along with the winemakers and vineyards that produce them –  have had some profound transformations in the past 30 years. Grape growers have successfully determined which varietals thrive in their vineyards,  have experimented with unique trellising systems, and explored interesting new areas for planting. The wines now have a head start because of the wonderful grape quality.

The winemakers have been upping their game by attending classes and working in wineries abroad –  bringing back with them modern winemaking  practices from the finest winemaking regions across Europe and the USA. Even highly regarded, award-winning winemakers from other countries are moving to Chile so they can  take advantage of the country’s grape quality – and to have full creative control to craft spectacular wines. It’s crazy awesome that we are able to receive the same high quality grapes and winemaking opportunities people travel so far to achieve. We are lucky to be a part of this wine journey with the vineyards and winemakers of Chile.

The grapes will be harvested very soon. Below is more in-depth information about the vineyards and the potential arrival dates. The season will be early, so dust off the crush pad, sanitize your equipment, and get ready for some fantastic winemaking.

We will have a Bootcamp class running during the Chilean Season. If you would like to join or hear more information please email Christina at cmusto@juicegrape.com. Spaces are limited and the class will be starting soon.

Winter in the Vineyard

This gallery contains 3 photos.

Right now the vines are dormat and enjoying a little sleep. If you drive through the vineyard areas you will see different types of grass and flowers growing in between the rows. These plants are not randomly growing in the rows. They were planted there for a reason (and no it’s not just because they look pretty). These plants are called cover crops.

Cover crops help protect and enrich the soil in a variety of ways. They help regulate vine growth, protect soil from erosion, improve soil fertility, draw away the abundant moisture, help with air quality, and introduce beneficial insects to the soil and vine.

The photos you see above are from Lanza-Musto Vineyards. At Lanza-Musto Vineyards we planted three peas, crimson clover, mustard, and oat throughout the rows. These are all full of nitrogen and other nutrients. Some rows have more crops planted than others. For example, the younger vines have the three peas mix because the younger vines need more nutrients. Where as an older vineyard might have a mustard mix.It is important to remember that vineyard maintenance does not start and end at harvest time. There are many things that need to be done in the vineyard throughout the year to ensure the vines produce quality fruit.
