Barrel sized wine production question

Hey guys! I normally hang out over in r/wine and saw this sub about a week ago. I know that most folks here make their own wine in small amounts. I'm looking for a source of information on how to make wine, at home...about one barrel's worth. I know one vineyard owner and one wine maker...but I really don't want to start asking them tons of questions when I'm just barely starting out. Thanks!
