Thank you for the details, got it!

My guess too but I was figuring someone had science to back up our guess. And I know carbonation could give an inaccurate reading but assuming flat beer it just gives me more questions: what is the mineral content of a beer brewed with say RO water? What happens in the mash, boil and...

I purchased a countertop RO system from APEC. It's a 4 stage system, hooks into my kitchen sink (you have to have a standard type faucet, not a pull-out or designer faucet) and hook it up when I need to collect water for brewing, then I just disconnect from the faucet once I've collected my...

I'm still wondering what it is with beer that wouldn't cause a TDS reading to be significantly different with 2 beers if one beer was brewed with straight RO and the other brewed with high minerals and high alkalinity, and all other factors the same. Assuming there is a taste difference, why...

Another option for purging your keg is doing a fermentation purge. Just do a search and you'll find lots of info but using the CO2 produced during fermentation from your airlock/blow off to purge your keg of air (you of course also have to set up a 'blow off' out of the keg as well). Very easy...

I used 4 ounces of new growth red spruce tips (because that's what I have in my backyard) in a 5 gallon batch of pilsner. Tasted similar to Rogue's Yellow Snow. I added 2 ounces at 5 minutes and 2 ounces at flame out. It did quite well in competition with the BOS judges split on it having...

Good to know the probes are sturdy. Thanks! I don't understand enough about conductivity and TDS obviously. I know there is a lot going on in the mash but in finished beer what is it that causes the TDS number to be so high? Is it the alcohol? Dextrins and residual sugars? Does carbonation...

Yes, I understand that it doesn't tell you 'what' but that's not my question.

OK, thanks. I wanted to know if it would damage the TDS meter to use it to test beer as I've not used one before. As far as useless and meaningless, I have one more question: can you explain why it's meaningless and useless? Is that because of the reactions that happen in the boil and in...

I just got a TDS meter along with my countertop RO system. Checked out the TDS meter on my tap water and distilled water but on the packaging one of the applications listed is for food and beverage testing. So this has me wondering if one can test finished beer for TDS. If so, can you share...

Thank you for the primer. I mistakenly posted this on the water chemistry sticky before realizing this was a huge annoyance to the author of the sticky... I've just purchased a countertop RO system for brewing and have a couple of questions related to brewing a pilsner with RO. I want to keep...

Sorry for my mistake of posting this here, have since started a new thread for the following post... Thank you for the primer. I've just purchased a countertop RO system for brewing and have only made it to page 15 of this thread so forgive me if the questions I post are answered somewhere from...

I didn't get the Brewmaster Edition as I was wondering the same thing...and wondered what would happen if the temp probe stopped working. Could I get a replacement, etc., etc.. What I do instead is use an infared thermometer on the outside of the Brewbucket (masking tape on the bucket as the...

I use it for sampling after sampling I just spray up into the opening with star san (I have a spray bottle that can spray upside down) and then I have a cap I put on the sampling port that I fill with star san. Works great. Without a cap I agree, not good enough to just spray it and let it be...

Yes, get things into focus on the microscope and then bring your smartphone in close to one of the lenses. You'll see a white circle, keep that circle centered on the screen and zero in by getting closer with your phone to the lens until the yeast come into focus. Takes a steady hand and a...

Not to derail this thread but drinking almost flat beer is like looking into the soul of a beer. Not always good but it gives you a clear view.

Ha ha! Yes, I do some spunding but still need CO2. My simple brew system uses CO2 to push my sparge water. Besides, like I said, it's a hobby and it's supposed to cost money. :)

I'm just wondering what folks around the country are currently paying for a 10# bottle of CO2? The price at our local place is now $20 for a 10# tank. If you don't mind posting, it would be interesting to know what folks are paying. I know it's likely the least expensive thing I have be...

I agree. Too many times I've been burned buying beer (any style but especially IPA's) from some smaller brewery with either little control or little care about their beer. I know, once it leaves the brewery they don't have much in the way of control of how it's handled but I've even been...

What he said. Even without doing everything low oxygen I've seen a huge improvement in my IPA's. I still do some things that are less than ideal for low oxygen but have had my IPA's stay fresh for months with just some process changes. Oh, and I don't have a beer fridge, so I'm serving just...
