3 volumes is fairly safe actually. I've done a lot of reading about the topic, and it seems that most people seem to be seeing bombs at 4+ volumes in standard 12oz bottles. For a bomb to occur at 3 actual volumes (disregarding miscalculations), it seems the bottle needs to be stressed or flawed. For my 2.75 gal batch this was 2.8oz dextrose.
I've cracked a bottle of the cherry graff and it's slightly carbed already. Slight reddish head without much staying power, great tart nose with a smooth, thick, sweet taste to it. The cherries come through strongly. Amazingly good right now, and once it's really ready I think I'm going to have a keeper. For the next iteration I'm not going to alter much, but I'm going to use 8oz carapils instead of the torrified wheat. I might go all-grain too to save a dollar, but it's just going to be 2-row. Going to stick with the 1lb lactose, 1lb caramel 20L, and sucralose at bottling.
