Sugar Observations ?

[MagickMuffin]

I have been noticing the various textures of sugar and was wondering if anyone else has also experienced the same.

I generally use Imperial Brand, but have chosen other brands as well.

First one on my list is powered sugar. I used to love American Buttercream, however, the last time I made it is was so super sweet I couldn't eat it.

Anyone else notice this as well? or Has my tastebuds changed and it just appears sweeter to me?

Second is granulated sugar. I've noticed the grains appear larger. I had to sift some granulated sugar and it has definitely changed texture, while some sugar seemed fine there were extremely large grains they couldn't pass through the strainer.

I love to make Italian Meringue Frosting and Divinity. I made some Meringue last week and the frosting was grainy. I made sure to wash down the sides of the pan to avoid this from happening and yet it didn't matter. Again not edible to me.

Has anyone noticed this with the sugar you use?
