The 70's was a revival period for home made wines. Your grandparents had made it but your parents thought it was naff. They would rather buy pub drinks, well mine did.
The information was also localised so in the UK root veg wines were often suggested along with hedgerow fruit. You remember 'food for free' by richard maybe.
Now the approach is more scientific making very palitable brews for the cost of sugar plus time. This really is a win win situation and it is rewarding.
