Can I track original gravity (OG), final gravity (FG) and ABV?
Yes. You can log measured OG and FG, estimate OG/Brix from your ingredients, and Fermolog calculates potential ABV and plots your gravity history on a chart.
Do I need an account to use Fermolog?
No account is required to use the core tracking features, and Fermolog does not sell or share personal data. Creating an account simply lets you sync and share batches across devices.
