I use a 15-gal kettle for 5-gallon batches 90% of the time. But when I’m brewing for an event or a party, I’ll do 8 or 10 gallons so that I’ll still have some beer left. That flexibility is worth the larger kettle to me.
See Klackitat Jim thread on and Denny’s Experimental Homebrew podcast on iterated/double mash approaches. We can go bigger ABV than our tuns allow with single or BIAB size constraints, if we get innovative.
I wasted a lot of money on my first 5 gallon system. Three years later I went to 10 gallons and used keggles, which are about the cheapest 15 gallon brew pot you can imagine!
It takes the same amount of time to brew 5 or 500 gallons of beer (except for shoveling the spent grain. lol), so if you like your beer don’t mess around with small equipment.

In 530 batches, I think I’ve only brewed a handful larger than 5 gal. I really have no interest in brewing larger batches.
I drink a lot of beer. :o
I brew 10 gallon batches, an occasional 5 gallon batch when I make a RIS, IIPA, barley wine. etc… Love splitting it with different yeasts. I just blew a keg of throwback mild brewed with WY1318 that was delicious, but am now looking forward to the WY1469 version that I will tap tonight.
Occasionally I will end up dumping beer that I get sick of drinking, but that is usually the result of brewing 10 gallons of something I really only needed 5 gallons of (like rauchbier), so it is my fault. Can’t go wrong with 10 gallons of pilsner.
