So I'm really jealous of brewpubs that can use large serving tanks instead of multiple kegs and prefer naturally carbonated beers. This led me to find out about keg fermentation and Spunding Valves. I've read of Spunding Valves on kegs, but I am wondering if I could just treat an HDPE Inductor Tank/Fermenter as a large serving tank. It makes so much sense because they have so much less work to do and need less time grain to glass if they're spunding. I've looked into it and from everything I've found HDPE should have no problem with higher pressures, does this make sense our just sound crazy?
The fermentor could be elevated above the tap for serving (no engine necessary) with a CO2 tank attached to keep the beer from oxidizing. Basically it just becomes an ugly but hopefully functioning cask/keg depending on the beer style. Does anything besides being a cheap skate stand out as off?
Obviously this only makes sense if you're brewing batches larger than a keg, and then chilling to serving temps becomes an issue. Could possibly try a built in immersion chiller if it doesn't fit in a fridge. If this still makes sense in a few months when I'm back from traveling I'm going to try it out.
