Remember the baby Chenin Blanc grapes you saw on the budding out page? We're peering down into that same vine in mid June after it has been "crown thinned". Crown thinning involves removing the canes growing up from the central portion of the plant. This allows for better ripening and spray coverage, among other benefits. Looking Down!
To the right, you can see that same cluster of grapes in late July. Getting big & round!
With each new planting in the Spinetta Family Vineyards, our practices improve. We hedge and mow our vineyards. A pair of shears on the front of the tractor cuts a trapezoidal swath down the center of each row. Hedging allows tractors and people to traverse the vineyard easily. With "offset planting", the plants shade each other less, the roots have more room, the soil's nutrient cache is better preserved, and the shears meet one plant at a time rather than two. Different Planting Methods
When spraying or dusting (we use sustainable integrated pest management (IPM) and organic methods), the offset plantings get better coverage than the block plantings. Indicated by the green arrows above, the sulfur dust (or wettable spray - organic methods to prevent mildew) reaches the "farther out" plant better (we skip rows when spraying.) Sixteen rows of vines are in one "section" of a vineyard - there's a wider road to drive down on either side. (During harvest, eight men are on either side of the truck.)

Most vineyards in the Shenandoah Valley sulfur at 7- to 10-day intervals. When it's 96 degrees or above, one can spare a couple extra days - but it always gets cool at night. If the dew point is met in summer, this can mean disaster for vineyards with poor spraying programs. A person must take a yearly class from the state dealing with viticulture, nutrients, pest mangement, etc.

Our vines are very healthy: no bad bugs or birds, no erosion problems, and no phylloxera. So, when you see a vineyard planted close to the highway with no space in between the vines and the fence, think about the sneaky things hiding there. Cars kick up dust - a habitat for mites, and vehicles also spread phylloxera. You can only make good wine from good grapes!
