If you really want to use the pizza crust yeast then I highly suggest you read the following:
Joes Ancient Orange Mead
Bread yeasts can make a decent wine or mead but you need to know how to use it. If you follow the orange mead recipe "EXACTLY" then you will come up with a nice brew. If you are intent on using your berries then make sure you follow the basics in the above recipe.
The things to know when making up your own recipe with bread yeasts.
1) they usually have a low attenuation and ABV limit. Meaning that you may get a maximum of 9% - 12% ABV where as most wine yeast go to 14%+.
2) bread yeast have a low flocculation rate. Meaning the yeast cells do not clump together and fall to the bottom well. So in the JAOM recipe when it says leave the jug alone for 3 months and do not touch. That is important. Also make sure you leave it somewhere for when you get ready to bottle you do not need to move it. Any disturbance will suspend the yeast again.
3) most recipes do not use a whole orange and rather just the flesh and zest leaving out the white pith. With bread yeast you make the recipe very sweet and you do use the pith because it adds bitter tastes that balance that sweet out.
I have not tried this but one change people say work well in a JAOM is to use a whole lemon rather than an orange. So lemon and berries may be something that could work well.
If you want to use sugar rather than honey then it is about 2 3/4 lb sugar rather than 3.5lb honey per gallon.
Feel free to study up on all this and learn how to use the bread yeast without making something terrible. Or go online or to a home brew shop and get a 99 cent pack of lalvin 71b or K1V-1116 and make a no fuss easy wine you will enjoy.
