I have just recently started my first batch of mead this past weekend. it has been fermenting for about 4 days now. My problem is that my mead is not bubbling enough right now, about one bubble ever 20 or 30 seconds, so it is fermenting. I am wondering if this is the normal rate for just 4 days or if I should take some step to correct this. My recipe is simple 4 gallons of water and about 14 pounds of honey with two packets of lalvin d-47 yeast. Any help would be appreciated. thanks!
