Others may disagree, but I don't care much for some of the items in that kit:
- The ale pails are notorious for not sealing properly, since they have no lid gasket. I'd go with the white food-safe buckets from Home Depot instead (~$7). They're only 5 gal, but recipes are scalable (a chem major should have no problem with that).
All of my fermenters are Ale Pails, Have had no sealing issues and a super tight seal is not necessary as while fermentation is going on it is all under positive pressure anyways.
- The bottling bucket is also a PITA. Mine has always leaked, no matter what I do. Instead, I just use another 5 gal bucket with my autosiphon.
Unless things have changed since I was doing the bulk of my bottling or if they changed things up, as long as you assemble your bottling bucket properly (number of and location of the O-rings they usually include a spare and do not explain it) you should be leak free.
- StarSan >> Iodophor. Get a 16-32oz bottle and you'll be good for a long time.
StarSan is easier, but they both are effective sanitizers.
- 8 oz. of cleanser won't last long. Go buy some OxyClean Free.
- You don't need a book, you have HBT.
- Don't bother with a racking cane. You definitely want an autosiphon.
- You can get the tubing at your local Home Depot or hardware store. I've never needed clips or clamps.
- I'd never put a thermometer in my fermenter. How the heck would you read it inside a bucket anyway? Opening the bucket during fermentation is asking for infection.
Not particularly. Beer is far more resilient than most people think. True, you want to be careful with sanitation, but opening your fermenter (as long as it is not done excessively) is fine. How else can you check for gravity to make sure it is done? Just be sure to sanitize anything that touches it and you should be fine.
In short, I think you can save money over that kit by buying only (and exactly) what you need.
That's just my two cents. Welcome to the addiction.
