Why Does My Favorite Craft Beer Have No Yeast

…in the bottom of the bottle…Seriously, can anyone explain the filtering process at a professional brewery? I drank a six pack of Flying Dog’s Raging Bitch Belgian Style IPA at 8.3 ABV and the bottom of the bottle was crystal clear…very perplexed about this.

they fine or filter the yeast out. then use CO2 to force carbonate, and fill the bottles. not as many breweries bottle condition with priming sugar
