Is there a transcript?
I’d rather read the interview than spend 36″ listening.

I don’t currently have transcripts available. I have looked at doing it through a service, but the technical brewing terms generally drive the price up for transcripting.

Listening to it is more then I would ever want. If you want it in writing, just visit any beer forum. He repeats it almost on a daily basis.

How do I in incorporate his method with BeerSmith 2.2.12?

Brad Bellows April 18, 2020 at 5:15 pm

Question: Have you done a podcast/interview with someone who uses a Robobrew V3 and batch sparging? This is the area that I am very interested in and would like to be far more efficient with my brewing.
