You can reduce this with a couple of steps. First, chill your cider to 'compact' what little yeast is still in the bottle. Second, be careful when carrying your bottle to where you are going to pour it to your glass. Don't slosh the bottle around, bang it on anything, etc. Just carry it gently, open the top and pour. When you pour, however, do it slowly, and leave the last 1/4" of cider in the bottle to avoid pouring the yeast into the glass.
Hope this helps.
