Not sure how long you've been brewing tjash but if you do some research you'll find some pretty skilled Berliner Weiss brewers don't boil at all. I boil for 1 minute. This sterilizes the wort and since you are not adding any bitterness from the hops with this style, you don't need to boil it. I've done this now with Lambics I make and it works very well. I wouldn't do this with other styles that you want to extract hop bitternees. But it works well for low hopped beers.
