I am planning to make a fruit batch for my wife and I have read on when to add the fruit and how, but is there a recipe that you should stay away from? This my be subjective to a point, but I don't think a Bock would be a good starting point. What wort would be recommended?
To make something your wife would like start by looking at what she likes to eat. Is she into tart or sweet food?
Lets assume she likes chocolate; then look at what goes well with chocolate: oranges, cherries, vanilla... you get the point. Then get a beer that represents the chocolate (stout/porter) and add the fruit that you decided on.
Lets assume your wife likes more tart things, then the easiest answer is lambic, but a pilsner or similar beer (bready/crackers) with some lemon zest to become a lemon tart could work. A weiss with tart fruit also works well.
Otherwise, take a beer that she likes and taste the beer with different fruit.
It is ultimately subjective, but historical tradition and commercial success does suggest there's an objective aspect, too. These are some of the things I've seen and/or experienced that work better/more accessibly than others:
- Blonde ale (Strawberry blonde, &c.)
- Hefeweissen/wheat ale
- Berliner Weisse (traditionally with a shot of woodruff or raspberry syrup; blueberry, apricot, peach (Dogfish Head Festina Peche is a great example))
- Lambic (Framboise (raspberry), Kriek (cherry), Cassis (currant), Pomme (apple))
But if you look at something like RateBeer's Fruit Beer ratings list, you'll see entries for almost every style category.
