Q: What size wort grant is ideal for a 7bbl brewhouse?

A: For a 7 barrel system, a 20 gallon wort grant is recommended. This provides sufficient capacity without being oversized.

Q: Can I convert a keg into a wort grant?

A: While possible, it is not advisable as the stainless steel alloys and fittings on a converted keg may not be properly designed for repeated exposure to aggressive brewery cleaners and high temperature cycling.

Q: Should I choose a grant with a false bottom or filtration screen?

A: It depends on your budget and clarity targets – false bottoms provide good clarity for most homebrew setups, while filter screens take it to the next level.
