Posted Sun Feb 3, 2013, 9:18am Subject: Whole beans to ground ratio after grinding?
Hey all, have a simple question. Today I think I made my first good cup of coffee, grinded the beans with a fairly cheap blade grinder but the taste was defintely greater than just pre-ground coffee. I'm using Eight O' Clock whole bean medium roast.
So I googled this exact question and the answer came up: "1 tbsp beans = 2 tbsp ground". I tried this today however my coffee seemed like mostly water after using 6oz to brew. (I really only like to drink 6oz in the morning).
So I dumped that and used 2 tbsp beans instead and that produced lots more ground, came out pretty well, so I'm guessing this is a good ratio to use?

Use a scale to weigh the beans and a ratio will not matter in addition to having a more consistent volume. Ditch the supermarket coffee and get a good grinder and the step up you just saw will be 10X larger and for the better.

Keep in mind, I'm the coffee with creamer every morning type. I rarely drink more than 6 oz at a time. Don't want to waste so much money on something I only enjoy every morning. Like I said today was definitely a step in the right direction with grinding them, it was SO good.

He's not saying that. Grinding the beans creates lots of little pieces, with gaps between - this means they will take up more room (e.g. 2 tbsp) but they will weigh the same as what you began with (ignoring anything left behind in the grinder!) Basically, do it by weight, ignore your tbsp measurements altogether! If you really can't be bothered to do weight, then keep your grind settings the same and pay attention to how much you are dosing...
Yes! The link to the burr grinder you posted will make a great difference!!
As soon as you sit down to a cup of hot coffee, your boss will ask you to do something which will last until the coffee is cold.

No that grinder is a fake burr grinder and it will perform the same as the whirly blade thing that is sold as a grinder. For other than espresso, this grinder will take care of all your needs at a reasonable price. Click Here (www.baratza.com)

Actually the ratio is pretty close to 1:1 for loosely packed beans and grounds. If you shake or pack the coffee it will change the density so you need to be consistent in how you measure to get consistent results. Also, the density can vary a lot from one type of coffee to the next, easily by 30%. This is why a scale is more accurate.
If you always use the same brand/type of mass produced coffee, weigh a measured volume at least once to determine the density, and consistently measure volumes the same way each time then you should do okay.

Yeah, makes perfect sense because when I used 1 tbsp beans to 2tbsp ground it came out to be very weak. 2tbsp beans to 2tbsp powder seems about perfect for me. If I'm going by grams, what is the measure? According to this chart someone linked me: http://blackbearcoffee.com/resources/83 I should use 10.6 grams of ground for a 6 oz cup, how much would that be in beans, or is that up to the coffee itself and requires me to actually experiment?

Since measuring whole beans by the tablespoon is going to be very inaccurate its probably not worth worrying too much about the actual density. Ballpark bean density is 0.4 g/ml which translates into 1.8 tablespoons for 10.6g of coffee. So 2 tablespoons sounds about right, as long as you don't mind the variation you're likely to get from brew to brew. I'd take a guess and say that you're probably not measuring your water very accurately either.
