We did answer your question, Lynwitte the whole thread is us answering your question, you just don't want to listen....
I'll say it again, as plain as possible, If you are drinking any of the 8 batches you brewed in the last six weeks
they are too young, you need to let them age, that is why they taste "grainy" they are still green. They will get better when they have been bottle conditioning for 3 weeks to a month, if not more.
Read this for an explanation....

There's things that you have to let the yeasts do, and rushing the process doesn't let them do it...for example, letting your beer sit in primary for 2-3 weeks after the 7-10 days of fermentation allows the yeast to clean up the mess of fermentation...when they are fermenting the yeasts are also putting out a bunch of proteins and chemicals that give your beers off flavors...when they have converted all the sugars to alcohol, before they go dormant, they swim around and clean up that mess...
Leaving the beer in bottles for a minimum of 3 weeks @ 70 degrees, allows the yeasts to clean up the mess they made fermenting the priming sugar..and the Co2 built up gets re-absorbed into the beer, and further cleans up stuff, and let's the various flavors come together....
This is especially important to you because it will mellow out that "grainyness" you are tasting.
This is not making Koolaid, it is dealing with living micro organisms...They have a birth, life, reproduction and death cycle, and that lifecycle is what gives us good beer. So let them do their job!
Read this blog as well....it shows what happens if you let your beers rest for awhile.
Really amazing stuff happens...

This isn't a numbers game, it's one of patience.
David 42 just answered the other guys question...
Grainy is really husk. Possibly due to a poor crush and/or poor sparging.
Try crash cooling the beer and keeping it cold for 4-6 weeks.
See that, the answer to fixing the graininess is
time!
If yours are already in bottles, then leave them at bottle conditioning temp for 3-4 more weeks...then chill them down for at least a week...you'll be amazed to see your graniness is gone...
Do you understand what we've all been saying, now?
