My first batch (red ale) is 4 days into primary fermentation and I realized that I neglected to compensate for boil off when adding water. In total I used five gallons, which based on the reading I've done here will leave me roughly a gallon short of the supposed 5 gallon yield. Is there an appropriate time to add more water to adjust for this rookie mistake? I figure I could do it when I transfer to my secondary fermentation carboy or just prior to bottling when I move it to the bottling bucket (or even leave it as is at the risk of the finished product being unbearably strong). Any thoughts? I searched the forums and my books for something similar but came up empty-handed. Thank you in advance.
