I am assuming this is a simple question but I wanted to be sure anyways.
When I am following a recipe that calls for dry hops and simply says “3 days”, I am assuming that means I add the hops to the fermenter approx. 3 days before I think I’m going to bottle, correct?
This is an area you can really play around with. Anywhere from not dry hopping at all, to adding to the fermenter toward the end of fermentation, to waiting till its done and pitching them, all the way to some guys who add them to the keg and dont remove them until the keg is empty. Its all personal preference and depending on what you are trying to achieve. Ive had good luck with tossing them in the fermenter once I hit terminal gravity, letting them soak and settle to the bottom for a few days, then just racking the beer. Anywhere from 3-10 days gives decent results. Ive also pitched them into the keg, in a hop sack, and left them in for the duration. No ill effects unless the keg lives for a really long time.
I’m trying both methods at the moment after listening to Jamil’s podcast on double dry-hopping. An added benefit should be by dry hopping at two different temperatures producing a more complex aroma.
I prefer five days instead of three days. Tends to give off the perfect level of aroma (in my experience), but it matters what style you are doing. I like dry hopping multiple days instead of adding it all at once. Makes the aroma a lot more complex. You could try adding some for 7 days, then 5 days, and then 3 days (as an example).
