The Master's Edition is a definite step up from the All Juice series. I have several of both in the works and the Master's has more aroma, flavor and body. I will have to add that mine are very young and I do think the MM kits will take longer to come around.
I will also add that MM has a higher level called the Meglioli line. It is a limited edition series only available in January, February and March. Since the kits will retail for around $200.00, I wanted to make some first, before posting for sale.We did a tasting ofthe 5 week old Barolo and Pinot Gris from this series in the store today. The result was "awesome". These kits are definitely a cut above the other kits on the market. I did not know a Pinot Gris could taste that good and it will be extremely difficult for me to age the Barolo.
I will definitely have these for sale next year. If you want to make a $25-30 bottle of wine from a kit, this is it!
BTW, the renaissance line of 16 liter kits is comparable to the Selection Estate series. I have made the Carmenere and it will be a very good wine. In May, I will start some more wines, but I have 14 carboys for the next bottling party and 5 of the frozen juices to start at the end of April, so the plate is full.
