I have used Harrisfilters Beer Brite for a while now, mostly when I keg lagers, I've found it to be good at what it does in general, no effect to the taste of the brew. If you don't mind the waiting game (I do) then you wont need them, but I tend to like production so "impatient" is my middle name ;-)

I find it hard to wait the recommended time before sampling my beer so have used these a few times. I've found them to work very well and have had no adverse affects to the taste..............probably for those more impatient brewers...........like me!

I used them on my 1st attempt at beer making. And to be honest I think I won't use it again, The product itself worked however time is a better brightener and is cheaper at 0p

I bought a couple of packs of these just to test really as I am new to home brewing. I followed the instructions and added them to my beer barrel of bitter and they did clear the beer quickly. I'm not a 100% sure but I think they have altered the taste of the beer slightly and I dont think I will add them again unless I have particulary cloudy beer.
