Your first mead

You do not need expensive or specialist equipment to make great mead. A basic kit can be assembled from homebrew suppliers or online for under £50 / $60. Here is what you need for a 4–10 litre first batch.

Traditional mead requires only three things: honey, water, and yeast. Nutrients are a fourth ingredient that modern meadmakers add to support healthy fermentation, and skipping them is one of the most common causes of stuck fermentation or off-flavours in first batches.

Use the calculator to determine exactly how much honey to use for your target OG, volume, and yeast strain. It will also calculate your nutrient schedule.

Water makes up 85–95% of your mead by volume, so its quality matters. Mead is more sensitive to water chemistry than beer because there are no roasted malts or hops to mask off-flavours.

For a first batch, good-quality tap water treated with campden, or lightly mineralised bottled spring water, will produce excellent results without the need for water chemistry adjustments.

Wild yeast, bacteria, and moulds compete with your mead yeast. Thorough sanitisation of all equipment that contacts your must is the single most important step to ensure a clean, healthy fermentation.

See the sanitisation guide for a detailed breakdown of sanitisers, technique, and common mistakes. The key points for a first batch:

• Use Star San at 1 ml per litre. Mix a fresh batch for brew day.
• Sanitise everything that will touch your must: fermenter, airlock, bung, spoon, hydrometer, test tube, siphon.
• "Don't fear the foam": Star San foam is harmless. You do not need to rinse.
• 30 seconds of contact time is sufficient. Drain excess, then use immediately.
• Sanitise as you go: do not sanitise equipment and then leave it sitting uncovered.

Honey is viscous and takes time to fully incorporate into water. Undissolved honey that sinks to the bottom of your fermenter will not ferment evenly. There are two main approaches.

Once the honey is fully dissolved, top up to your target volume with cool water. The must is now ready for a gravity reading.

Before pitching your yeast, measure the original gravity (OG) of your must. This tells you how much fermentable sugar is present and allows you to calculate ABV once fermentation is complete.

See the hydrometer guide for detailed instructions on how to take a reading, correct for temperature, and interpret the result. In brief:

1. Draw a sample of must into your test tube using the siphon or a turkey baster.
2. Lower the hydrometer into the sample and spin it gently to dislodge bubbles.
3. Read the scale at the bottom of the meniscus (the lowest point of the liquid curve).
4. Record the reading and the sample temperature. Apply a temperature correction if needed.

A typical first mead targets an OG between 1.080 and 1.120. Below 1.070 will produce a light, low-ABV mead; above 1.130 risks stressing the yeast and stalling fermentation.

If your OG is lower than planned, you can add more honey. If it is higher, add more water. Recalculate your nutrient additions after any adjustment.

Yeast requires dissolved oxygen at the start of fermentation to synthesise sterols and unsaturated fatty acids, the building blocks of healthy cell membranes. A well-oxygenated must produces a larger, healthier yeast population and a cleaner fermentation.

Honey must is naturally low in dissolved oxygen. Aerate before and immediately after pitching yeast. Methods in rough order of effectiveness:

1. Stir vigorously with a long spoon or whisk for 3–5 minutes until the must is noticeably frothy.
2. Use a wine whip (degassing wand) attached to a drill for 1–2 minutes.
3. Pour the must back and forth between two vessels several times.
4. Use an aquarium pump with a sanitised aeration stone, most effective but not required for a first batch.

Honey is almost entirely sugar with very little nitrogen or micronutrients. Yeast needs nitrogen (measured as YAN, yeast assimilable nitrogen) to build proteins and reproduce. Without supplemental nutrients, fermentation slows, stalls, or produces off-flavours.

The modern approach is staggered nutrient additions (SNA): splitting the total nutrient dose into several smaller additions early in fermentation rather than adding everything at once. This keeps the yeast fed without shocking them.

Read the nutrients guide and the TOSCA 2.0 protocol for the full picture. The calculator will calculate exactly how much Fermaid O, Fermaid K, and DAP to add and when.

Dried yeast must be rehydrated before pitching. Pitching dry yeast directly into must stresses and kills a significant proportion of the cells, up to 50% in high-gravity or high-alcohol environments.

1. Heat 50–100 ml of clean water to 35–40 °C (check the packet for your specific strain).
2. Add your GoFerm PE dose to the warm water and stir to dissolve.
3. Sprinkle the dry yeast onto the surface. Do not stir yet. Leave for 15 minutes.
4. Stir gently to combine. The mixture should look creamy and active.
5. Allow the rehydrated yeast to cool to within 10 °C of your must temperature before pitching.
6. Pitch into the must and stir to distribute evenly.

A yeast starter is an optional step where you grow a larger population of yeast cells before pitching. This is more common in high-gravity batches (OG above 1.120) where a large, healthy cell count at pitching is important to avoid a stuck fermentation.

For a first batch with an OG below 1.120 and a fresh packet of dried yeast, a starter is not necessary. Proper rehydration with GoFerm PE is sufficient.

To make a starter: dissolve a small amount of honey in water to reach approximately 1.040 OG, rehydrate your yeast into this instead of plain water, and leave it for 12–24 hours at fermentation temperature. Pitch the entire starter into your must.

Temperature is one of the most important variables in fermentation. Too cool and fermentation slows or stalls; too warm and yeast produce fusel alcohols and off-flavours that take months to condition out, or never fully disappear.

Check the packet for your chosen yeast strain's recommended temperature range. Most wine and mead strains ferment best between 15 °C and 22 °C (60–72 °F). The yeast strains guide lists the temperature range for each strain.

Fermentation itself generates heat: the must can be several degrees warmer inside than the ambient room temperature. Place your thermometer on the side of the fermenter at liquid level for the most accurate reading.

Putting it all together. This is the recommended sequence for a first brew day. The calculator handles all the numbers, so come to brew day with your recipe already planned.

1. 1

   Plan your recipe

   Use the calculator to set your target volume, OG, yeast strain, and nutrient schedule. Note down all the numbers before you start.

2. 2

   Gather and weigh ingredients

   Weigh your honey on the kitchen scales. Measure your water volume. Have your nutrients and yeast packet ready.

3. 3

   Sanitise all equipment

   Mix a batch of Star San. Sanitise the fermenter, airlock, bung, spoon, hydrometer, test tube, and anything else that will contact your must.

4. 4

   Dissolve the honey

   Add honey to water and stir until fully dissolved. Top up to target volume with cool water.

5. 5

   Take your OG reading

   Draw a sample into your sanitised test tube. Record the gravity and temperature. Adjust with water or honey if needed.

6. 6

   Aerate the must

   Stir vigorously for 3–5 minutes until the must is frothy with dissolved oxygen.

7. 7

   Rehydrate your yeast

   Heat water to 35–40 °C, dissolve your GoFerm PE dose, sprinkle in the yeast, wait 15 minutes, stir gently.

8. 8

   Add first nutrient dose

   If your SNA schedule calls for a dose at pitch (many do), add it now, stir gently, and degas first if CO₂ is present.

9. 9

   Pitch yeast

   Cool the rehydrated yeast slurry to within 10 °C of the must temperature, then pour it in and stir to distribute.

10. 10

    Seal and label

    Fit the airlock and bung. Fill the airlock to the fill line. Label the fermenter with date, recipe name, OG, and yeast strain.

11. 11

    Place at fermentation temperature

    Move to a stable location at your target fermentation temperature. Check within 24 hours for signs of activity.

12. 12

    Continue SNA additions

    Add remaining nutrient doses at the scheduled gravity checkpoints. Degas before each addition.

Once fermentation begins, your main jobs are monitoring temperature, making your scheduled nutrient additions, and taking gravity readings every few days to track progress.

Fermentation is typically complete when gravity readings are stable over 2–3 consecutive days and the airlock has stopped bubbling. Take a final gravity reading (FG) to calculate your ABV using the hydrometer guide or the calculator.

After fermentation, you may want to stabilise and optionally back-sweeten. See the stabilisation guide for a full walkthrough of chemical stabilisation, cold crashing, fining, and back-sweetening options.

Understanding pH and how to adjust it will help you produce cleaner, better-balanced meads as your batches become more complex. See the pH management guide for the theory and practice.

Save your batch in the calculator and use the dashboard to log gravity readings, notes, and status changes as your mead progresses from planning to active to complete.
