This weekend weather could not have been more perfect for pruning our grapevines. Over the years, it has become an event we both dread in some ways and look forward to in others. It is a bit of an endurance test like running a marathon. You start out pruning one vine correctly then multiplying that times a few thousand. Each vine is similar in some aspects and completely different and unique in others. Pruning is a series of very quick decisions which cannot be undone, there is no ‘undo’ button and a mistake may take a few years to correct. Incorrect pruning can result in a severely reduced crop or a high volume crop which lacks many quality characteristics, and every variation in between.
Learning to prune is best started with a text book, then try your hand in the field and as my vineyard mentor John Schwaesdall says “Listen to everyone, then make up your own mind about how to proceed based on your conditions”, I’ve found this to be sound advice.
Pruning has basic principles which are true in all situations; however there are nuances which are specific to your varietal, microclimate, personal preference, wine-making technique and wine style. There are a few absolutes, but not many. Start out by speaking to someone in your area growing the same varietal successfully, this conversation and the peak at the freshly pruned vines is worth gold.
