priming sugar math...

Postby JeffPorter » Thu Feb 09, 2012 9:15 pm

Just a quick check of my math, for those of you numerically inclined.

I think there's about 4 gal of IPA in my carboy - if 3/4 of a cup of corn sugar primes a 5 gals, would 2/3 of a cup be sufficient for (approx) 4?

Thanks...

Sure, 0.6 is exact, but 0.66 would work.

I just picked this one up at Shoppers, clearance end for $20.00.

I have been using a cheapo from Crappy Tire, but it died a few days ago.

I need a scale anyway for bread baking...(and hops measuring...)

My grand-father in law got me a cheapo one that didn't work...

KwaiLo, you picked up a SALTER for 20 bucks at SHOPPERS? Man, I wonder if any close to me have any.

$9.99 2/3's off right now. works for up to about 7lbs. I use mine for grain and even light amounts of hops.

That's a great deal. I like the old-school mechanical scale, but I do need something for smaller hop measures. What's the precision on that one? (I was thinking more along the lines of <1 Kg capacity with 1-2 g precision).

I've measured sub 1 ounce amounts of hops. I've never checked the calibration on mine but you can also switch ounces/grams/pounds too. They say it is accurate down to a gram.

Derek, I've heard this one at Lee Valley is pretty good. Not that you can just pop into Lee Valley anymore now that you are in Kelowna.

Definitely get a scale first if you can. 3/4 cups is a very rough guideline, and it really depends how coarse/fine the sugar is. I have seen 3/4 cups measure out to more like 6 oz. The one time I used the measuring cup method it resulted in bulging caps and overcarbed beer.

I have the Starfrit one mentioned above and I really like it, but it doesn't measure down to a couple of grams. I tried measuring dried yeast on it, and up to about 5 grams it still read 0.

Yeah, when measuring grain it seems to jump in increments of .05 ounces, which is about 1.5 grams
