My take on your questions is "not really" and "sort of yes".
I have used generic tannin in fruit wines for decades. In the past week I've taken delivery of 3 red wine tannins and 1 white wine tannin, and am starting experimentation. I have 2 red wines in 3 containers each, and each will receive a different specialty tannin.
If I can figure out a 4th container for each, I also have plain 'ole tannin, and I'd like to see how that differs.
And yes, they are expensive. The experimentation will help me decide if the specialty tannins are worth it.
