If your going to buy something might as well buy something want to use. No point buying twice. If you wanna do 23l brews then you'll need a bigger one. They are pretty good quality and will do the job. :thumb:
Good thing about smaller batches is that you have to brew more often so more beers to try (or is that brewing more often a bad thing :hmm: ). Depends what you want!
I had a 25 ltr boiler given, brewing with it was not good, so I bought a 40 ltr Buffalo, the spare space is excellent so when you get the old boil rolling rapidly there's no spillage :thumb:
Initially I stuck with the tap the boiler came with, but since have changed to a proper job, much better and made a better filter as well :thumb:
