Anyone know where I can get some sanke ring removal knives?



Morebeer adds to the cart, but comes up with $0 price. St. Pats brewing has them, for $35 for a 3 pack. Can't seem to find them anywhere else for reasonable price. Is homebrewing.com the same as morebeer?

cheers.

I have had better luck with those small flat-headed screwdrivers companies give away as advertisement. They are free... just sayin'.

I agree with Wort. I bought some of those knives from chicompany.net I think. I've never used them. They seem flimsy to me but maybe I don't know how to use them.

The cheap little screwdriver works great.

Holy cow, what a thread. I don't know what I've been reading for the past 3 hours, but I'm glad I did, lol. I have a simple question that was probably answered a million times, in the early stages of fermenting you have a blowoff tube prior to putting on a spunding valve.

So my question, how is this done without contaminating the process? The CO2 is being released quickly so no danger there, but I'm still confused exactly as to functionally this process is done.

Thanks.

John

This is how I pressure ferment. I connect a blow off tube to my setup without the spunding valve for the first 48 hours. Just a tube into a bucket of Sanitizer just like you're fermenting in a carboy. Then remove the tube attach the spunding valve and gradually ramp up the pressure.

It works great for me.

The reason I do it this way is I ferment 15 gallons in a Sankey. When I've tried the spunding earlier in the process it gets plugged with hop particulate from the krausen and the pressure skyrockets. It's a pain to keep removing the valve and cleaning it. So I've gone to this hybrid technique and it seems to work well.

Let us know how you do.

Others use a water-filter housing to act as a water trap. I start my fermentations at 5psi and stay there until the very end.

Well for starters some use a blow off others don't (I'm in the latter camp). That being said; I have done it with an airlock in the past. I have my pressure gauge attached with a quick disconnect. If I want; I simply attach an airlock to the disconnect with a short length of hose for a few days them swap it out for the pressure gauge. The co2 is heavier than air so it acts as a buffers and won't let contaminated in via air.

I generally ferment 11-12 gallons in a sanke. With this much head space I've never really had the need for a blow off. I set mine to 7psi and let her roll. The pressure also keeps krausen down.

I just finished a 15 gallon ferment in a sanke and I went the airlock route for the first three days then installed my pressure rig. It was a pilsner in budvar yeast and it was a violent fermentation. Finished product came out great and is currently in the kegerator.

What temp did you ferment at? I don't have much temp control on my unit so I'm sticking to ales right now. I put a box fan blowing on the Brewhemoth conical in the basement and I can keep the ferm at 66-68F at the peak of activity, I doubt this is good enough for a lager and I hate to gamble with 15gal of beer.
