Oh better tell @sift666 about that - I'm sure he has many things to say about farting.
That is all very exciting. But I'm surprised about grapevines needing an incline. I have a picture in my mind of vineyards in then Marlborough region here, and the Wairarapa, and that image is quite flat. Or is it a tiny incline that wouldn't be noticeable to the naked eye?
I actually think it might depend on the variety. I have seen some flat vineyards, but for the most part around here they're planted on sweeping slopes. I'd have to ask my husband why.
Will be interested to see how it all pans out
