Taking the plunge into all grain and starting with the basics... I have a 10 gallon stainless steel brew pot and looking at burners. Can I "get away" with 60k BTU or do I need more?
60k is plenty for 5 gal batches in a 10g pot. I have a 100k I use for heating strike water - like Aleforge says it will get you there faster - but use the 60k for actually boiling my wort. It gives me more control and no chance of scorching it.
