Any of the high end Cabernet's will give you what you are looking for. Wine Expert Estate Series Cab's are good although I do not see the Woodbridge listed in the catalog anymore. The Mosti kits look very promising.I have made 4 different Cab's and all were very good.
Stay away from the lower end Cab kits such as the Vintners Reserve. While it makes a nice, flavorful wine it is on the thin side and you don't really get a true Cab experience. A very nice table wine though.
If you want a big red and don't mind a blended wine, try the Crushendo's. I have made one Crushendo and a couple other grape pack kits and they are all very big, full, rich, what ever you want to call them wines. Many of them are a blend of Cabernet Sauvignon with other grapes. Well worth checking out.
I have never made a Mosti kit but plan on trying. They are 100% juice that surely will offer great body to the finished product. With more juice comes more solids which will offer the potential for a fuller wine. Of course they will take more time to age but the wait should be worth it.
One last thing on that line. Any good Cab kit will take a couple years to reach it's full potential in the bottle. If you have the time and patients to invest that time and can keep out of it, you will make a very fine wine. Make a few cheaper kits to drink to get you by and put those big kits away to age well. So far I have 2 kits that are right at a year that I have not touched yet. I can't say that for all of them but the two I feel have the most potential sit untouched.
