FAQ
Common questions
How long does mead take to ferment?
A 1-gallon session mead with Lalvin 71B typically finishes primary fermentation in 2–4 weeks. After that, you'll want 2–4 more weeks of clearing before bottling. Mead is not a weekend project — plan for 4–8 weeks minimum from brew day to first bottle.
My mead smells like eggs. Did I ruin it?
Probably not. Hydrogen sulfide (egg smell) is a sign of stressed yeast — usually from insufficient nutrients. Degas vigorously by stirring, add a small dose of Fermaid-O, and continue fermenting. The smell usually dissipates. If it persists after bottling, adding a sanitized copper fitting to the mead for 24 hours can help bind the sulfur.
Can I use bread yeast?
Technically yes, but the result will be noticeably worse. Bread yeast produces off-flavors above about 6% alcohol and is optimized for CO2 production, not clean fermentation. Wine yeast packets cost $2–3 and make a meaningfully better mead. Don't use bread yeast.
How do I know when fermentation is done?
Take two hydrometer readings 48 hours apart. If the gravity hasn't changed, fermentation is done. Don't rely on airlock activity — airlocks stop bubbling before fermentation ends, and a slow fermentation can fool you into thinking it's done early.
What's the TOSNA protocol?
TOSNA stands for Tontitown Staggered Organic Nutrient Addition. It adds Fermaid-O in small doses on days 0, 1, 2, and 3 of fermentation rather than all at once. The staggered approach keeps yeast healthier and reduces off-flavor risk. GotMead.com has a free TOSNA calculator.
Do I need to heat the honey?
No. Many meadmakers heat the must to dissolve honey faster, but heating also drives off delicate aromatics. The current community consensus is no-heat — just mix honey into room-temperature water thoroughly, add nutrients, and pitch. It takes more stirring but produces better flavor.
