I have to say, I thought I knew a fair bit about the basics of homebrew. How wrong was I, already I have learned new things, such as degassing or freezing used pulp for further batches of wine. I am so glad I have joined this forum.
If you get that detailed the weather can affect the fruit too. Personally, as I see it the soil, if appropriate for the plant/tree/vine etc isn't going to affect a wine as much as how you produce the wine, additives used etc.Thank you Scooter. I'd better make sure I've got plenty of pens/pencils in the house then.
One thing I will pay particular attention to is location of fruits, my wife has done some research into allergies with foods and where it is grown. Acids and minerals in the soil can make a big difference to people's reactions to certain foods, so I am well aware of variations this could make to the end result in my wines.
