I love Erdinger and wheat beers in general, after trying some of Erdginers others types I wondered what other beer out there is close to Erdinger taste
It also goes by the names: Weizen, Weissbier (Weißbier), Wheat beer, etc. etc.
Lots of German breweries produce great examples of this style of beer: Weihenstephan, Franziskaner, Schneider, Aying. I believe that if you like Erdinger, many of these companies' wheat beers will be to your liking.
IMHO the closet to Erdinger Hefeweissbier would be from Franziskaner (obviously this is a very subjective assertion, YMMV). It would be interesting to line some of these up for a taste-difference test.
But you may be able to find German-style wheat beers brewed in many other countries. Do not be confused with an "American Style Wheat-beer" / BJCP Category 6D. This is a significantly different sort of beer.
Given your liking of these sorts of beers, you might also enjoy Belgian style wheat beers, collectively known as Witbier.
