Start by preparing the hibiscus infusion. Combine the dried hibiscus and 1 gallon of water in a large pot.
Bring the pot to a boil, then turn off the heat and steep the hibiscus for 30 minutes.
Meanwhile, combine the honey with 1 gallon of water in the fermentation vessel.
Add the frozen strawberries and blackberries and stir.
Use a strainer to filtrate the hibiscus tea.
Pour the hibiscus tea over the berry honey mixture, stirring intensely.
Add the wine yeast and stir well.
Once the fermenting vessel is prepared, attach the airlock and allow the mead to ferment for 2-4 weeks or until fermentation has stopped.
To ensure optimal yeast activity and achieve the desired flavor profile of the mead, it's essential to keep the temperature of the fermentation vessel within the range of 60-70°F (15-21°C) throughout the fermentation process. The temperature has a striking effect on both the yeast activity and the ultimate flavor profile of the mead.
