I have a good idea Martina. Why don't you send me a bottle of each of your different wines. I could taste them for you and then advise on which ones to give for Christmas. I would not even charge you a fee for doing this.
You could use fruit from palm trees and make a "Palm Sunday" wine. I thought of this about 2:00am this morning when I couldn't sleep. Isn't it amazing the things that come to our minds in the middleof the night??
BTW ... Somewhere on the forum I saw a recipe for Pindo Palm Wine.
