Thanks Scott. I'm not sure if this got lost in the post somewhere, but I have not started anything or purchased anything yet. The only thing I have done so far is recruited friends (and myself) to save all the bottles I will need to get started. I am at the "all-grain" section of "How to Brew" now and am probably going to stop by the book store and pick up another book to read...I'm thinking Papazian's book.
I'm just trying to get a good grasp of the concepts/methods first, save a good sized chunk of money, and then buy the items I need to get started. I most likely will not get started until after the new year, mainly because money is going into savings for Christmas. Once I decide on a setup, I may start buying smaller pieces, maybe get the mash tun built, but that's all for now.
I guess I'm still a bit confused about the whole setup I had originally suggested. Over lunch today, I watched a video again that I had watched a few weeks ago. It was John Palmer, author of "How to Brew" showing a ten gallon brew using 10 gallon igloo mash tun and HLT. https://www.youtube.com/watch?v=h5J8S5nBdUc&list=WLo0wfCJNs1cqyqzIIpwgpw63AKoNojJdy
I know someone had mentioned brewing only lower gravity beers with that type of setup, and the question I have is...is he brewing a low gravity beer in this video? It makes me wonder if I do a fly sparge with the two cooler setup, and can brew a 10 gallon batch of a brown ale, I'd be happy. And if I were to want to brew a higher gravity beer, couldn't I just use the 10 gallon system but just brew a 5 gallon batch?
If I were in your shoes, I'd start with the 10 gallon igloo mash tun. If you're going to fly sparge, then you'll have to have the HLT! Fly sparging is much more advanced than batch sparging for someone just starting out. Making the fly sparging arm requires that you have a HLT (added expense) and build the fly sparge system (more added expense). I don't mean to discourage away from fly sparging though.
It's just that it adds cost and complication right from the start. If you start with just the igloo cooler mash tun and batch sparge until you learn the brewing process, you'll still make great beer that way.
We had 5 different set ups in my driveway this past Saturday. Four of the five were batch sparge and one was fly sparge.
Fly sparging also takes about an additional 45 minutes to an hour longer over batch sparging. You can make just about anything in your 10 gallon mash tun, as long as it's a 5 gallon batch. I got 1.089 starting gravity out of my system on Saturday. I did a ten gallon batch with basically a 5 gallon recipe in each 12 gallon mash tun, and they were no where near full. I've gotten as high as 1.100 SG out of my 12 gallon mash tun.
Trust me when I tell you that your 10 gallon mash tun is a great starting point. It will keep your costs reasonable at start up, while not causing you to purchase something that you can't use after you upgrade. If you start with the 10 gallon igloo cooler and batch sparge and later decide that you want to go to a larger mash tun and fly sparging, it's as easy as getting that 70 quart cooler and using it for a mash tun, and repurposing your 10 gallon mash tun into a 10 gallon HLT.
The only thing you'd have that you won't be able to re-use if you switch to fly sparging is the bazooka screen or manifold that you use in the bottom of the igloo cooler. Fly sparging requires a manifold in the bottom of the mash tun, so that you pull the wort down evenly through the grain bed when you fly sparge. It sprinkles on top from your HLT and goes straight down through.
With batch sparging, you can get away with a bazooka screen, which is just a long stainless mesh tube that hooks to the outlet. A bazooka screen runs about $18 at my home brew supply store. So it's not that big of an expense.
Let me stress, with a 10 gallon igloo cooler, you'll be able to brew just about anything in 5 gallon batch sizes. With the 70 quart cooler, you'll be able to brew anything in 5 gallon batches and most beers in 10 gallon batches.
Batch sparging is easy.
Fly sparging isn't difficult, but it isn't as easy as batch sparging. The learning curve is a little steeper.
Is the book your reading John Palmer's "How To Brew"? If it is, you're off to a great start!
Also, I don't know where you're located at, but look for a local homebrew club and attend the meetings. You don't need to be brewing to join a homebrew club. Make brewing friends now. Most homebrewers would welcome the opportunity to help you get started right. I know our club would welcome it.
