Ladies and gentleman, Harvest has arrived. The grapes arrived like the first rain of Fall: They showed up abruptly, without warning and aren't going away. Actually, the first grapes of Deerfield's 2009 vintage appeared on the crush pad in the middle of bottling. The crew split in two with one team manning the sorting table and the other team running a skeleton crew on the bottling line. It was very cool how everything had come full circle so that the very beginning and end of the winemaking process were happening concurrently, side by side.
Everyday since then we've been receiving literally tons of grapes and have been staying at the winery well into the evening to finish processing them. So far we've crushed about 12 tons of Pinot Noir and about 6 tons of Sauvignon Blanc. Depending on what kind of grapes we're crushing and what we are trying to do with them, the configuration of the crush setup changes. For example, red wines like Pinot are fermented initially with the grape skins so the process looked like this:
The grapes arrive in the large macro-bins described in "Bin City" and are placed one at a time in the tall dumping device. The dumper can be precisely controlled by a worker on the sorting table, who empties the grapes into the hopper at one end of the table at a speed comfortable for quality sorting. About four people man the sorting table, keeping constant vigil for any bunches of grapes that don't meet Deerfield's high standards. There are many criteria for acceptable grapes but some of the factors that cause us to toss the grapes include over or under ripeness, mold and raisining. Often the only way to tell whether a bunch is good or not is to taste it. I've never eaten so many grapes in my life! We throw away a sizeable percentage of grapes that we paid for. But it takes grapes of only the highest quality to make wine of the highest quality. Next the grapes fall into the destemmer, which does 90% of the job. The destemmed grapes then fall onto a shaking table which most of the seeds fall through. Lastly the grapes fall onto the berry sorting table where the remaining stems are removed along with any other dissatisfactory grapes that escaped the first sort. The grapes fall off the end of the line into another macrobin. Those in turn are dumped into a larger bin intended for fermentation instead of transport. Once full, the bin is placed in the cave where it awaits the inoculation of yeast to begin maceration.
But that's just one way to skin a cat. Sauvignon Blanc isn't fermented with its skins, so once the grapes have been sorted they go straight into the press. Because they won't be destemmed or furthur sorted it's important to weed out the unripe grapes the first time. The juice is pumped straight from the press to one of the large stainless steel fermentation tanks. The process of making white wine is really much easier.
Harvest is in full swing now and I've already started working 12 hour days. The crew is really starting to become a team and work together. Tempers are already flaring, and pressure is mounting. Harvest is a very dramatic time. Though the work is hard, it is fun to be part of such a dynamic process and everyone is clearly excited for what lies ahead.
Because of my hand I've been given a new job until it heals. Learn just what it is next time!
