If they hold in even one particle of the Hops that's better than the muslin bags we can buy today. They are positively worthless.
The tea bags arrived today. I immediately filtered some iced tea that had been setting for several days following a July 4 food drive effort. There was visible puffy sediment on the bottom of the transparent plastic bottle. The bags I ordered filtered-out all that sediment and left behind a beautifully-clear tea. The more tea I filtered, the slower became the process. These things really catch even the tiniest sedimentary particles. It's my opinion that pelletized hops would
NOT get through these bags. Too bad for y'alls that I do not know how to post a picture. If I could, you'd see for yourself the filtering power of these bags. Now that I know how fabulously these bags filter, I'm tempted to make a hop tea and drink it just to taste how powerful would be the flavor of one ounce of pellets in a liter of charcoal-filtered tap water.
