Ive made a Shiraz, a Malbec and just finished a batch of Merlot. The Malbec turned out better than I hoped. My remaining Malbec was mixed in with the new batch of Merlot in various proportions to see how it turns out.
Ive also tried a banana wine, that was a disaster. A tea wine that wasnt too bad but a little too tanic. Ive also just finished a cherry wine that im waiting for it to clear and age a little.
Ive definitely found that going for the better kits makes a big difference. I like the ones that come with seeds and skins as I like wine with more body.
