I can tell you one to be careful with; the Penn State book should be great but I made the mistake of following their guide to making strawberry wine. Whoever proof read the book should have had to drink that first attempt.
They told you to add x tablespoons of acid when in actuality it should have been teaspoons. I questioned it but did it anyway (to prove how gullible I can truly be). What started out as 5 gallon ended up being
17 gallons by the time I got the acid balanced. The good news is that every time I do something stupid like that I work harder to recover from the error and that wine usually turns out to be the best liked of that year.
All I'm saying is if you get that book and an addition seems questionable, add the qty requested in small increments and measure and taste as you go... In all honesty I bought if for fruit winemaking and do like the format, it's a good book.
