If you take a look at the wine thread Tweaking Cheap Wine Kits.
On this forum , it has a strong following.
If you look for the same subject on Google it's usually near the top.that shows me that there is a need for affordable kits for the beginner and
For a decent everyday wine.
Even the moderate priced kits with help can make a good finished product, but you have to work at it.
I don't really think the overall cost of a kit is a deciding factor as to why some people don't take up the hobby. No matter how you look at it, you can make your own good quality wine for less than you can buy it at the store. I think it's more that people today want instant gratification. And sitting around waiting for a kit wine to finish and then aging it for months or years is just too much.
