There is a wide variety of choices when it comes to fining. All a matter of personal choice as to if you want to use them. Personally, I have never had to add the sparkolloid to my Skeeter Pee, it always clears on its own. In fact, I do not add fining agents to wines in general. The exception is bentonite prefermentation with pear or peach. (and of course if provided in kits I follow the directions). But yes, sparkolloid is great stuff..so is isinglass and SuperKleer, especially if you run into something that simply will not clear with proper bulk aging.
