Pouilly Fume - Appellation maison

Then mid week I had this no-name unknown-vintage home made Pouilly Fume. A friend gave this to us as a present. While he is from Burgundy, this wine is actually from the Loire. At first it tasted slightly home-made, smelled great, but just had a hint of self-production about it. It tasted good though. I liked it even more on the second day. Don't know anything else about it.
