100% agree... double batches are great... but they're the best when you can keg them both. Bottling drives me mental too.
I have both kegs of a double batch sit in the kegerator side by side. When the first one blows, usually just as it's staring to come to it's peak, change kegs and the second keg is in it's prime. :icon_chickcheers:
That's why i need 3 more kegs for my 4 taps. So i have a total of 8. Can be changed over as soon as the first one blows.
