Yeast is an interesting thing. See, it’s a fungus. And it changes things — for the good, and the bad. It makes bread go bad, but wine taste delicious. Moldy cheese can either be a delectable treat, or a cause for throwing it in the trash can.
But whatever the case, it changes what it consumes. It may have been grape juice, it may have been unleavened bread. But it changes those objects. Sometimes we don’t want change, but when yeast is involved we really don’t have a choice. We must hang tight and, hopefully, find ways to enjoy the ride. If we don’t, we’ll merely complain and possibly miss out on a great opportunity. But we’ll only catch it if we’re watching closely, otherwise we’ll deem it wrong. Like sourdough bread or a delicious Belgian ale. Both of which quite tasty, but someone had to have the guts to try what change tastes like.
