Just added my hop tea to my brew prior to bottling (I forgot to scale down to 10L and added 25g of Challenger to the water).
I didnt want to use MrsMQ fench press as I didnt want coffee grounds in my beer and MrsMQwould kill me if her coffee started tasting like hops. What i did was fold a paper kitchen towel like in the vid below. Then after soaking the pellets in 1/2 pint of 80C water for 25mins, I held the folded paper towel over another pint glass and pour everything in to the paper towel. It worked really well seperating the tea from the spent pellets, although I did need to give the towel a gentle squeeze to get the majority of the tea out of the pellets
