Well I'm 100% in we closed on the (expansion) property last Thursday. I think my first step will be getting the 'conditional use' permit from the county which will allow for a store and facility (which principally prepares our farmed product for sale) and also a tasting room.
Update. So I was told by 1 woman at the county that we needed a conditional use permit. But her coworkers all said they didn't think so. I called OLCC, TTB, tax assessor and read the law myself. Apparently we are not building a 'winery' we are building an agricultural manufacturing and processing facility. The difference is because we won't have a tasting room or on-site sales or be open to the public. All of our sales will be internet based and from 'special events' where we will also advertise our wine. So this is good news because it saves over $10k in permit fees and we don't have to build stupid things like an enclosed garbage area that's a minimum of 9x12 even though we just have a 30 gallon garbage haha. And 2 labeled parking spaces. Ag permits are very cheap and I wired our new house and it passed on the first inspection so I'll be wiring the new 'grape processing facility' haha.
