A few notes about this Excel spreadsheet:
- Yup, it treats your kettle as an ideal cylinder. If you have a weird bottom, it may not perfectly reflective of your true volume
- Setup the sheet by choosing your units (english/metric). Input your kettle diameter and height in the green boxes in the purple region
- When it's time to measure, using a yard stick in your kettle (I use a metal one) and input the height in row 4. Row 5 will give you the volume both as read and minus a boil expansion (wort roughly expands 4% when at boil)
- To use target calculations, just enter the target start volume in Row 7 and your final target volume. Input your current OG in Row 6. Everything else is all dandy!
- You can also input additional boil sugars in rows 11,12 and 13 to add gravity boosts.
