why do you need to strain it?? wouldnt a filter work better as a strainer all the yeast will still go threw. I think there are 1 micron filters (thats prob wrong just guessing) Pretty sure G&G had one from memory I thought about it but more stuff to clean and sanitise and buy and to be honest if you learn to pour the beer properly its still clear, maybe last glass full it a little less clear but all taste the same unless you pour it wrong and get big hit of yeast
