I will usually leave my IPAs in primary for three weeks. They they get kegged and carb for a week. After that I start to serve.
Three weeks is more than enough time to finish primary fermentation on a 7% beer.
Thanks for the responses. I'll take a gravity reading at 3 weeks and depending how that sample tastes I'll dry hop for a week before bottling.
Also. According to the recepie which was followed it should be between 8 -8.5% alch.
