What Wyvern Mead Calculator does
Built for precision, not approximation.
TOSCA 2.0 nutrient scheduling
Enter your honey and yeast. Wyvern calculates your exact YAN requirement and generates a staggered addition schedule: GoFerm rehydration through to the 1/3 sugar break. No spreadsheet required.
Honey variety database
15 research-backed honey varieties with fructose-to-glucose ratios, pH adjustments, and YAN offsets. Wyvern alerts you to fructose stall risk before you pitch, not after you're stuck.
Batch tracking from calculator to glass
Save your recipe as a batch, log gravity and pH readings, tick off SNA additions as you go. Every batch keeps a full fermentation record.

About Wyvern Mead Calculator
Wyvern Mead Calculator is a tool built by a small-batch meadery based in Switzerland, currently in development. We make traditional show meads, fruit melomels, spiced metheglins, bochets, and session meads, all brewed with a focus on honey quality and fermentation science. Our recipes and products are coming soon.
We wanted a tool that works in any unit system, and lets us record and track every batch from first gravity reading to bottle. It grew into something we thought the wider meadmaking community could use, so we opened it up.
