Lalvin QA23 yeast

Video Description
Our fermentations have been acting… strange. 🤔
So today we’re running a homebrew experiment to find out if water type affects mead fermentation.
We tested three different waters:
• Tap water (house-filtered)
• Bottled purified drinking water
• Bottled spring water
Each batch used the same honey, yeast, nutrients, and fermentation conditions so the only real variable is the water itself.
🍯 Ingredients Used (per half-gallon test batch)
1 lb (454 g) wildflower honey
48 oz (1.4 L) water
¼ tsp Fermaid-O nutrient: https://amzn.to/4cw6sb4
Lalvin QA23 yeast: https://amzn.to/4brxz7Q
Over three weeks we tracked:
🍯 Fermentation speed
🍯 Gravity readings
🍯 Final ABV
🍯 Aroma and flavor differences
The results surprised us… and may change how you think about the water you brew with.
If your fermentations have been slow, inconsistent, or just weird, this experiment might give you some clues.
