Does the type of yeast I use, fresh or dry, make the final bread taste any different?
YES. I believe so! I always use fresh yeast when possible, although I do have a few dry sachets in the cupboard for when I am in a proper pinch.
Fresh yeast has real character and it may sound silly, but I feel like the resulting bread tastes more bready! There is a much more satisfying and moreish flavour to a loaf made with fresh than one made with dry. Whenever I am in that pinch and have to use dry yeast, my bread always tastes like it is lacking a little something, like it's not as great as it could be!
I am yet to be tested in a blind taster but I feel like I could tell the difference easily.
