We let the brew go a little long this week. After 9 warm days it’s a potent batch but with the sweet Texas grapefruit we have (1/2 cup) and a full tbsp of sugar. We made the big batch grapefruit and added just 1/2 tbsp sugar to the small batch for our plain (we tried a little extra sugar due to the strength). We’ll check it after 3 days on the shelf.
