Tips for Better Wine: How to Improve Every Batch
You've made a batch or two. The results have been good — but you want better. These are the techniques and habits that consistently separate a good home wine from an exceptional one. None of them are complicated; all of them make a noticeable difference.
1. Take temperature seriously
Fermentation temperature is the single biggest variable you control. Fermenting too warm (above 24°C) produces harsh, fusel-heavy wine with a "hot" alcohol character. Too cold (below 18°C) and fermentation stalls, leaving residual sugar and potential for instability. Aim for a stable 20°–22°C throughout primary fermentation, and don't let it fluctuate more than 2°C in a single day.
2. Degas properly — every time
Carbon dioxide dissolved in wine makes it taste harsh and prevents it from clearing properly. After fermentation, when you add your fining agents, degas aggressively — stir vigorously with a degassing wand or whip for at least 2 minutes, until you no longer see CO2 bubbles escaping. Under-degassing is one of the most common causes of hazy, astringent wine.
3. Give it more time than the instructions say
Kit instructions list minimum timelines. They tell you the earliest you can bottle, not the optimal time. Wines that are allowed extra time to settle, clear, and condition before bottling are almost always better than those rushed through the process. If your wine is still hazy after the recommended clearing period, wait. Bottle-clear wine is always worth the extra week.
4. Top up your carboy
Headspace (the gap between the wine and the bung) is your enemy. Oxygen in that space will oxidize the wine over weeks, stripping colour and freshness and introducing flat, sherry-like flavours. Keep your carboy topped up to within 5cm of the bottom of the bung at all times during aging. Use a similar wine, grape juice, or water if needed — the small dilution is far preferable to oxidation.
5. Keep your sulphite levels up
Potassium metabisulphite (K-meta) is your wine’s preservative and antioxidant. If you’re aging wine for more than 3 months, add a small campden tablet (or 1/4 teaspoon of K-meta powder dissolved in a little wine) every 3 months during aging. This keeps your sulphite level high enough to prevent oxidation and microbial spoilage.
6. Use oak strategically
Oak adds vanilla, spice, structure, and complexity — but too much is worse than none at all. If your kit includes an oak sachet, follow the recommended timing and taste frequently. You can always add more time on oak; you can't take it away. For premium red kits, consider sourcing additional oak spirals or cubes for extended aging directly in the carboy.
7. Store your wine properly
Once bottled, wine needs stable storage. The enemies are heat, temperature swings, light, and vibration. A cool basement (12–15°C) with consistent temperature is ideal. Keep bottles on their sides to keep the cork moist. Avoid storing near appliances that generate heat or vibration. White wines are more fragile than reds — drink them within 12–18 months for best results.
8. Keep notes
Write down your starting SG, fermentation temperatures, racking dates, and your impressions of each batch. Over time you'll identify patterns — which kits you prefer, which conditions produce the best results, which tweaks made a noticeable difference. Good winemakers, amateur and professional, keep detailed notes.
9. Upgrade your kit
The simplest way to make better wine is to use better juice. Moving from an entry-level kit to a mid-range or premium kit (Selection Series, Estate Series, Cellar Craft, RJS En Primeur) produces a noticeably more complex, structured wine. The techniques are identical — only the raw material changes.
