I made 4 batches of extract brew (dry yeast)and bottled with priming suger. I then made the switch to AG and made 4 batches (liquid yeast) and force carbed in a keg. The taste difference between the two is pretty distinct. The bottles are sort of sharp? tasting and the keg beer is so smooth. The carbonation was perfect on both. Just want to know what made the difference? The yeast? Priming sugar? Just being AG?
