I don't ask many questions on this newsgroup but I ALWAYS read the
postings EVERYDAY and greatly appreciate the efforts of those who
respond with their expertise. I have learned so much from reading
these postings! THANK YOU!

Q1. Isinglass ... After reading Jon Iverson's book (Home
Winemaking) it appears that John uses Isinglass quite often along with
bentonite (and speaks very favorably about it). However, in spite of
the excellent information and chart on finings in Lum's manual,
Isinglass appears to be absent. Also, Jack Keller's website mentions
Isinglass briefly but no detailed information. Is this a good agent to
use? Are there any drawbacks?

Q2. Using both + and - fining agents. I have used bentonite and
Sparkaloid at the same time (that is, I add one then 5 minutes later,
add the other). Is this okay or should I use one, wait 30 days and
rack, then use the other? If I use bentonite and isinglass in the
future, can these be used together or should I use only one then rack
then the other?

Thanks again in advance for your help!
