All of my batches taste awesome before bottling, then after carbonation they taste very cidery.

"Cidery
Cidery flavors can have several causes but are often the result of adding too much cane or corn sugar to a recipe. One component of a cidery flavor is acetaldehyde which has a green-apple character. It is a common fermentation byproduct and different yeasts will produce different levels of it depending on the recipe and temperature. Cidery flavors are encouraged by warmer than normal temperatures and can be decreased by lagering.
If it is caused by aceto bacteria, then there is nothing to be done about it. Keep the fruit flies away from the fermentor next time."
If I can't use white sugar or corn sugar... what can I use???
