1. If the question is water or volume
Use water chemistry when minerals, dilution, or mash pH are the question. Use sparge and boiloff tools when you are planning strike water, sparge volume, and kettle losses.
- Mash pH or salts: water chemistry calculator
- Mash/sparge volume: sparge water calculator
- Kettle loss: boiloff calculator
2. If the question is fermentation or hops
Use yeast calculators before brew day when pitch rate, viability, or starter wort are uncertain. Use hop tools when substitutions or bitterness need adjustment.
- Pitch rate: yeast starter calculator
- Viability or DME: yeast support tools
- Hop swap or bitterness: hop chart and IBU calculator
3. If the question is packaging or finished beer
Use carbonation calculators when beer is ready to package. Use ABV, hydrometer correction, and calories tools when interpreting gravity readings or finished strength.
- Bottles: priming sugar calculator
- Kegs: keg carbonation calculator
- Strength: ABV and hydrometer correction
Frequently asked questions
Which calculator should I start with?
Start with the calculator that matches the next real decision: recipe, water, yeast, hops, gravity, or packaging.
Do I need every calculator for every batch?
No. Use the tools that match your process risk. A simple extract batch may need fewer tools than an all-grain lager.
Should I use hubs or individual calculators?
Use hubs when you are not sure which tool fits. Use individual calculators when you already know the specific question.
Can I build the full recipe first?
Yes. The recipe creator is a good starting point, then calculators can refine water, yeast, hops, and packaging.
