Including a flask and stir bars, it cost me about $50.00 all up. Breaking it in right now with a Belgian Tripel!Ryanhttp://westaussiebrewcrew.com/forum/index.phpnoreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-10006452726684768042008-03-24T14:15:00.000+01:002008-03-24T14:15:00.000+01:00Ah.. Didn't think of that, and I'll take your word for it. :)<BR/><BR/>Regarding the link to VWR; I dont think they sell to "regular people". At least what they told me last time I met with them (via work). Registering as a company would do the trick they said, but it might be he was mistaken...Oleknoreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-1998466142574069432008-03-19T13:05:00.000+01:002008-03-19T13:05:00.000+01:00Olek, <BR/><BR/>Yes I agree. Adding the stir bar to the flask before heating sanitizes it. But don't add it while it is boiling as this will cause it to boil over. Trust me on that, as I've tried it. :)grovehttp://www.blogger.com/profile/02090575637277836287noreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-25922795069142749572008-03-19T01:38:00.000+01:002008-03-19T01:38:00.000+01:00Why don't you just add the magnet directly to the flask before boil-up. Less sanitizing to do. The stir bar is teflon coated and can definetly take the heat.Oleknoreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-65323506491074451682008-02-03T16:18:00.000+01:002008-02-03T16:18:00.000+01:00I've built a stirrer and it works wonders. You really get a lot of yeast for a relatively small amount of wort. I've been using just 1L starters and have been getting short lag times even for lagers, though of course a 2L starter won't do any harm, just as soon as I get some larger erlenmeyers.<BR/><BR/>I don't think you can achieve the same effect using a blender. It will probably spin too fast, will be hard to sanitize effectively, and will certainly be noisy, if it's anything like the blender I have! I can't bear to hear our blender for more than a few minutes, let alone 2-3 days!matdmhttp://hoppingmad.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-80688771073540937992008-02-02T14:36:00.000+01:002008-02-02T14:36:00.000+01:00I'm not trying to be a smart ass I'm very new to brewing but Why not just use a blender or similar device?

It will also keep the yeast in suspension at all times making sure that there are no dead spots and makes for each contact with the wort sugars. The stirring increases oxygen levels and will drive off the CO2 (which suppresses yeast activity).grovehttp://www.blogger.com/profile/02090575637277836287noreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-54442669291471439552007-11-20T23:05:00.000+01:002007-11-20T23:05:00.000+01:00From what I can tell it helps you get things done more quickly. So if you have an old yeast that takes a while to start (like my WLP002 I just used) it could save you a day or two.<BR/><BR/>Are there other advantages?Adamhttp://www.blogger.com/profile/08522250477305289784noreply@blogger.comtag:blogger.com,1999:blog-6756861315815236395.post-66688265169646655562007-11-20T22:28:00.000+01:002007-11-20T22:28:00.000+01:00I was reading about these in BYO.

Can't justify the cost yet though. I suppose 17 or so batches of beer made with propagated yeast would be enough to pay for it.Adamhttp://www.blogger.com/profile/08522250477305289784noreply@blogger.com
