I've been curious to blending, I love blended reds! I actually got a kit called trinity red a blend; cab sav, cab franc, and merlot. I think it's by cellar classics. Haven't started it yet, I've been cranking out whites for the summer. So there's an option, but I also stumbled upon an app the other day for blending wines. I didn't download it because it wasnt free, but the apps are out there.
Happy blending!
