I sometimes use sanitized plain shot glasses to weigh down the hop bag.
I have heard of other people using glass marbles.
Pellets, your maximum extraction is achieved after 36-48 hours.
Where did you get that fact? I don't believe it. Do you have any evidence to support this?
Great thread! Awesome idea about the shot glass. In 2 weeks I'll be dry hopping in a keg and wondered how I would do it.
Think about it. The hops are totally pulverized which means a massive amount of surface area is exposed to the beer. When you dry hop, the beer already has a ton of alcohol in it, which is literally the perfect solvent for dissolving hop oils.
Anyway: Source. Now with more science!
The 24 hour number is achieved with agitation, but the release of CO2 and dissolution of hop pellets will provide more than enough motion in your puny 5 gallon batch to get fantastic aroma very quickly. Very little benefit is derived from leaving them longer than this. My big batches (where extraction efficiency is better) tend to get grassy in about a week of pellet dry hopping because of all the pulverized plant matter.
Just remember, when you draw beer from the keg it draws from the bottom where your shot glass and hop bag will be... You may want to search other threads to find the best method to dry hop in the keg...
That data is different than was found by hopsteiner. This says you are still extracting a lot up to 7 days, and continue to extract aas and linalool for a couple of weeks.
