I am building a keezer, and right now I'm in the planning/parts-acquiring phase. I have never owned a kegerator, so this is a learning experience for me. My goal is to be able to serve my homebrewed beer on tap. However, I also plan to keep a keg of seltzer on hand, and I might occasionally want to serve wine or cider on tap. Also, I sometimes brew sour beer. I imagine I will continue to bottle any beer that's really sour (since I consume it fairly slowly and it sometimes benefits from aging in the bottle), but I might want to keg sour beer on occasion as well. So in other words, from time to time I will be serving beverages in a lower pH range than you would get if you were only serving clean beer. My keezer will have four faucets (as mentioned above, one of them will probably be dedicated to seltzer). I am thinking about buying two Perlick 630ss faucets (currently on sale at Adventures in Homebrewing) and two Edge-Tap (manufactured by Krome) 316 stainless steel faucets (also available at Adventures in Homebrewing, but not currently on sale). I would use the Perlicks for clean beer and the Edge-Taps for everything else—sour beer, seltzer, cider, and wine (also sometimes for clean beer if I happen to be serving more than two at a given time). My thinking is that the 316 stainless is more suitable for the really low-pH stuff, while the standard 304 stainless Perlicks are adequate for clean beer. So my first question is, am I thinking about this correctly? Is pH a concern with sours/ciders/wines or would I be better off just getting 4 of the Perlicks? Or would it be smarter to get all 316 stainless so that everything is interchangeable? (By the way, I don't care about the effect that mixing and matching faucets would have on the appearance of my keezer—I'm just thinking about functionality, maintenance, etc.) My next question involves the shanks that I will need. First, I am going to get all stainless shanks (of course), but I assume that if I go with the 316 stainless faucets, I will also want 316 stainless shanks and tail pieces for those faucets (like this one). Is that right? It seems to me that it would defeat the purpose to go with 316 stainless for the faucet and then 304 for the shank. Also, that 316 shank I linked to has a 1/4" bore, instead of the standard 3/16". That seems as though it's not good, right? Should I try to find a 3/16" shank instead? (It's easy to find 3/16" shanks in 304 stainless but I'm having more trouble finding them in 316 stainless.) Second, my keezer collar will probably be an inch thick. About how long a shank would you recommend? I am thinking I could get away with a 3 1/8" shank (like this one), but should I maybe go with 4 1/8" instead? (The woodworking part of the project is still up in the air, so I might end up with a thicker collar, but the effect on the required shank length should be pretty obvious.) Finally, what about a nipple shank (like this one)? It seems good to me but there may be some factor I'm missing that makes it a bad idea. Maybe it's harder to clean? Thanks in advance for any help you can give me.
