Old story about a tourist or weekender stopping at a winery. He may have had his wife or family with him. Vague memories of an old gate (or possibly a doorway) being spooky or being involved somehow. I think he eventually gets bound up with the winery somehow. I read this quite a while ago and it may have been on the 5 letter site.
The only story that I recall with a winery in it, is black coffee's The Gunny and Lenore where Lenore's parents pass down their TX ranch and move to Napa Valley where they revive a money losing winery. Course there might be others, but either I haven't read them or have forgotten about them…. If you expand things a bit to include farms with grapes on the side there's also Dual Writers Recluse and Ghost which has its own spooky Ghost and mountain….
Thanks for the try but the one I'm trying to remember is probably close to 10 years older than those. It was a guy and maybe his family stopping at a random winery, maybe for a wine tasting. Vague memory that it might have been somewhere in California's gold country.
I actually have a winery in two of my stories. But neither one of those is anything close to what they are looking for.
