Anyone have a running list of yeasts that are having sulfur problems? Might be handy for future reference.

What about using Cal Gas? I posted this on the last page.

Here is a purifier that I've come across before. Its pricey at $215.00. Says it'll last 4 tanks, but didn't list the size of those tanks. http://co2purifier.com/vici-metronics-co2-purifier/ "VICI Metronics gas purifiers dramatically reduce contaminant levels and absorb a greater variety...

Can CO2 Calibration Gas be used for carbonation? It's 99.999% pure CO2. 17 Liters for $34. Shipping is also $30+. http://www.calgasdirect.com/carbon-dioxide-pure-gas-99-999-in-17-liter-cylinder/

Wow, ive been getting 78% by squeezing the hell out of it. Is your crush like flour?

I've only did one "semi" LODO batch, so I don't know how relevant I am. But I did an IPA (White Labs Cal Yeast) and started with 50 mg/L of SMB. I also used the Yeast/Dextrose. I never had any indication of sulfur. It's carbonating right now, but one day after dry keg hopping, it was grassy...

Pulled a sample after burst carbing at 30psi for about 12 hours. The dry hops were very harsh and grassy (.5 oz citra and .5 oz Amarillo for 3 gallon batch). I'm assuming this is oxidation of the hops since the keg wasn't pressurized during the initial few hours. I'm hoping it fades with time...

From Yeast Biotechnology: Diversity and Applications: "Regarding fermentation, zinc is well known as an essential ion for alcohol dehydrogenase (ADH) (Magonet et al., 1992), which facilitates the conversion of acetaldehyde into ethanol at the end of fermentation." The way I understand it...

I transferred last night. Geez, I had QD's, lines, co2 bottles/regs, starsan going everywhere. I have to get a process down. The starsan purge went well. The transfer from fermenter to keg had some bubbles that would go away. I moved the line and closed the valve a little. It helped some...

People are mentioning yeast nutrients, but be aware of which one you purchase. I know a lack of zinc in the wort can cause acetaldehyde problems. Reverse osmosis and distilled water are devoid of just about everything. Tap water has some zinc in it. The only yeast nutrient that contains...

Have you ever had that problem before? Some wyeast nutrient might help if that's the cause of it. It's the only nutrient that contains zinc. Ive heard of people adding zinc tablets also.

Yea, I have seen the chart. To get under 1ppm O2, you would have to purge 12 times @ 30 psi, and 16 times to get undetectable levels. That was one thing I was doing wrong in the beginning of kegging. I would simply fill my open keg with an autosiphon (introducing O2), cover, then purge 5...

Did you use distilled or RO water by any chance? Ive read that a lack of zinc in the wort can cause acetaldehyde to form.

Could you not suspend the hop bag before transfer? I'm thinking I'm going to put three hops in a bag with some marbles. Ill use dental floss coming out the lid. The length of the floss will be enough to keep it 1-2 inches off bottom and the marbles should keep it weighed down. So, add dry...

I tried that last time, but I feel like a good bit of the aroma left through the airlock. Also, I am having second thoughts about using a bag, but not sure what else to use. I scooped the bag out after transferring and the bag was full of beer. It was like a small bucket in that it was...

One thing I didn't mention was I am dry hopping in the keg. I was looking into putting the starsan into the keg, then transferring that to another vessel, then transfer beer. However that cant happen with the dryhops needing to go in before transfer.

So you're saying hook a gas QD to the keg and tubing with one end in sanitizer and leave the PRV closed? I guess in that case the co2 in the purged keg would just bubble through the sanitizer instead of through the PRV.

Yea, the German Brewing pdf on oxidation is the reason I am watching all aspects of it now. I brew 3.25 gallon batches and recently purchases 3 gallon kegs. After subtracting the trub at the bottom of the ferm, headspace should be minimal in the keg. However the fermenters are about 5.3...

Thanks, didn't think about connecting another line to the gas in of the keg while filling. Yes, the Speidel is airtight. Theres a valve on the bottom, and the top where a normal airlock would go. Ive attached a picture (not mine, but same brand). The valve on top is open with a blow off tube.

I'm curious if anyone has done this. I've never closed transferred anything, but I have some tubing ready to go on my Speidel for transfer on 8/17. I have 2 of the plastic valves that come with it on the bottom and top. The top has a blow off tube running out of it. I am assuming I do the...
