Visiting the winery in Bordeaux, if you only look at the vineyards and don't taste the wines made in each village, you can't understand the style of each house. Fortunately, the visitor center said that there is a winery called Piganeau nearby that is willing to receive us. When he arrived, Mr. Brunot, 71, the owner, was directing the workers to load the barrels of wine. His workshop was in the yard, in front of the vineyard, where he usually lived with his wife. He had three wineries, and had been camped for four generations by his son's generation. He said his grapes were also handpicked by employees. There were ten stainless steel vertical reaction tanks in the workshop, and he outlined the fermentation process, as for the specific procedures, not only complicated, but also impossible to say, and this is the secret of the wineries. In fact, the climate is different every year, resulting in different grapes harvested. The craftsmanship and personnel of each winery are different, so that the final wine tasting is also different. It can be said that there are too many factors affecting the wine product to be controlled. It is often said that everyone has a Hamlet in their heart, and to say winemaking, everyone will brew tens of thousands of wines. Mr. Brunot leads us to the cellar, explains the role of oak barrels, and opens a bucket on the spot for us to taste. Then, to the tasting room, selected a few bottles of red wine from the past year to open let us experience the difference.
