The Best Way to Make Wine

I've made three batches of Petite Sirah. Every batch has been a big hit at home and with our friends an neighbors. I've aged the wine in 20 L oak barrels for about 3 months and they seem to have aged well. I have also blended the Petite Sirah with Cab and Zin (also from William's California Wine Concentrates). Every batch has been a great success. I'm finding it hard to consider any other method of making wine after so many successes, and no failures.
