I've used mine once. What i found is that you will need to have a few of them so as not to overload the ball and underutilise your hops.
38g of pellet is too much for one ball imo
I use them to dry hop and in the boil if I am doing a beer that does not need much hops.
I don't like putting in more than about 25-30g of hops in mine.
I used one for the first time last week. Put in 50 grams for dry hopping with a large polished rock shaped like an egg to get it to sink, but even then it didn't sink properly. Same story with anything I suppose. :huh:
i use both the smaller tea pot size and the larger 3" types,but dont over pack them. also the hops can be sprinkled around the veggie patch to keep the snails away . ..cheers..spog...
