How to center and change site title font in Twenty Thirteen

I created a twenty thirteen child theme and I’m trying to change the font of the site title and aligning it in the center. I installed a plugin call Easy Google Fonts, but when I try changing the site title font, it changes the entry titles as well. From what I understand, both the site title and entry titles fall under h1. Is there a work around to this? I tried :

.site title {
	font-family: “Homemade Apple”;
	font-size:	44px;
}

but there was no change. Tried a couple more that I found on web, to no avail. Please help. Thanks!
