The 10% Hard Lemon Soda: A High-Gravity "Super-Alcopop" Protocol 🍋🧪

In the Lab today, we are tackling one of the hardest flavors to ferment: Lemon. Because of the extreme acidity, most lemon brews stall out at 5% or turn into "rocket fuel." This protocol uses a specific pH buffering technique and a high-tolerance yeast shunt to hit a massive 10% ABV while keeping that crisp, refreshing soda finish.

This is the ultimate summer party brew—designed to be served over ice, crystal clear, and dangerously smooth.
