Obviously this produces something that can be sold and isn't a service. However under the skill descriptions it lists brewer as a profession not a craft. I am assuming that Vinter would fall under a similar function.
I think this calls for a little creative rules interpretation. Look at some of the other professions: Cook. What does a cook make? Meals. But the cook doesn't have a shop with "finely crafted meals for sale". Or Lumberjack. What does a lumberjack make? Logs! But you don't see a pile of logs for sale, "U pick Ur Log" at so many SP per foot.
Obviously, a brewer can sell: an ale. But how much ale does a good brewer have to sell to make, say the 7 GP that a 1st level brewer (Prof: Brewing 4) makes in an average week? At 2 SP/gallon, about 35 gallons! Without modern technology, that's a fair bit of brewing. And that's just the selling price, to cover the costs of ingredients and equipment, he'd have to brew quite a bit more. So, it's not completely unreasonable for brewing to be a profession instead of a craft. A bit of a stretch, but not too much of one.
Now, common wine sells for 2 SP per pitcher, and based on weight, a pitcher must be about 3 quarts (call it 3 liters for those who use the metric system). Again, that's over 100 quarts, or about 26 gallons...a
lot of wine to make in a week. Those 10 GP bottles of wine? Those take
years to make, and are much more wasteful of raw materials. Only the finest grapes go into bottled wine, the rest can't be used. So, it's not like you can just sit down and spend a week crafting a 10 GP bottle of wine, or a 12 GP bottle if you roll well. You spend time working at a vinyard: Setting up trellises in the spring, trimming vines in the summer, picking grapes in the fall, tending the casks in the winter. It's a profession.

Secondly, would Viniculture fall under Kn: Nature well enough?
I'd say it fits that category better than any other. The only rivals are geography (knowing just what plots of land will bear good grapes), local (knowing local viniculture), and history (how different styles of wine were developed, what vintages were good years). But by far, nature seems best.
