Want to make two brews in seven hours?
Purchase the Grainbrother to go alongside your Grainfather and make a second brew concurrently. Once you have finished mashing your first brew, you can transfer your mash basket to your Grainbrother (which is essentially a Grainfather, minus a grain basket and chiller) and start a second brew!
This way you don’t need a second grain basket or counter flow wort chiller and can make two different brews in about seven hours.
