Hi, I was reading this forums because I'm planning a trip to Ireland, I saw your question and I wanted to help you, since I'm a big beer fan from the Milan-Turin area.
If you're in Milan you absolutely have to visit the "Birrificio Lambrate" Brewpub, in the centre of the city close to the Lambrate train station. It's a cosy wood-panelled pub, open Mon-Fri for lunch and dinner and Sat-Sun only for dinner: great atmosphere and very good brews, they concentrate on very clean and easy-drinking beers, like the "Magut" pilsner (it means bricklayer in Milanese dialect), the "Urtiga" pale ale, "Ligiera" amber ale and their famous "Ghisa" smoked stout. The pub gets really overcrowded in the evening, so my advice is to visit it at lunch or before 8PM.
There are many other places in the city and in the suburbs but since you asked for the 2-3 most worth I'll jump forward.
Another great brewpub in the Milan Area is the "Birrificio Italiano" in Lurago Marinone (Como province) about 20-30 mins by car north of Milan. It's more like a posh restaurant so if you want to dine you absolutely have to book in advance. This brewpub is renowed for its world-class pilsner, the "Tipopils", but also brews other excellent beers like the "Bibock" bock, a Weizen, a dunkelweizen, a more hoppy pils "Extra Hop", and two strange beers, only bottled, named "Cassisona" and "Scires", the former with blackcurrant and the latter with cherries. Both food and beers are a bit pricey.
The Turin area has a little few brewpubs but with great quality. Apart from Baladin which you already know, I suggest you the "Grado Plato" brewpub in Chieri. It's a quite big but quiet pub, restaurant and pizzeria, and the food is concentrated on snails. It may sound awful but I assure you that they are very tasty! The beers are quite good, I suggest you the "Sveva" pilsner and the "Spoon river" strong bitter, If you're lucky you'll find the "Sticher", inspired by the Düsseldorfer Sticke.
A brewpub in downtown Turin that I like is the "Piazza dei mestieri", with good food and good beers, I especially like the doppelbock and the Kölsch but all their beers are quite good.
In Turin there's another great brewery, "San Paolo", but they haven't a pub, so you can try to phone them and arrange a visit. There's another great brewery in Marentino, 20km east of Turin, it's called "Loverbeer" and focuses on wood-matured beers and experiments with wine.
In Turin, just outside the "Lingotto" (a former car factory now converted in a mall) there is "Eataly", a big (and expensive) food market that focuses on quality food; downstairs there is the wine and beer market and there you will find a lot of bottles from italian microbreweries! Unfortunately italian micros almost only use 0,75 L bottles so they may add much weight to your baggage. And they are extremely pricey.
South Turin, about 1h of driving, quite near Baladin in the Cuneo province, there are two interesting places.
The first is called "Birrificio Citabiunda" and is in the nice town of Neive. The brewer concentrates on spicy and sweet beers, they all are worth the detour and the food is very good as well.
The second is called "Open", is situated in Cinzano (in front of a massive Diageo factory) and comes from a joint-venture between Baladin, "Birra del Borgo" brewery (near Rome) and Eataly. It's a radical-etno-folk-chic pub that only serves italian beers (6 on draught and around 70 bottled). It's a bit biased towards Baladin and Borgo beers (how could it not be, in the country of the conflict of interests!) but you'll find a good selection of beers from brewers from any part of the country.
If you wanted 2-3 places I think this is enough <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="

Plan carefully your visit and check the opening times since 99% of pubs and brewpubs in Italy only open in the evening. You may visit my website[/url:1dz6lydc], it's in Italian but it's just a list of pubs, micros and brewpubs in Italy, with POIs, addresses, phone no.s, opening hours, and so on.
Have a nice trip! <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="
