Hi all, quick question:

For a partial mash, what is too long and what would be the result of mashing too long? Let me clarify why I ask:

I brewed an ESB this weekend and used the following ingredients. 3 pounds Maris Otter, 2 pounds 2-row US, 1 pound Crystal/40L and 3.2 pounds of Xtra-Light DME.

I mashed the 6 pounds of grain at 153 degrees. Problem was that I got distracted and did not sparge until after a full 90 minutes of mashing. Target OG was right on at 1.051 prior to closing up the primary. I used 1.5 q/lb of water too for the mash (9 total).

Does the longer mash time cause problems?

Bottled: Imperial Hefe, Saison, Apfelwein
Kegged: ESB, Foundation Stout, Brothers English IPA, Kolsch, Bavarian Hefe
Secondary: Abbey Dubbel
Primary: Imperial Cherry Bavarian Hefe, Imperial Cherry Brussel Abbey
On Deck: World Class ESB, BKRye

i usually mash for 90 mins and consistently hit my targets. i cant say that i know of any real issues with mashing for too long. once conversion is complete, its complete.
ill keep my money, guns, freedom, and can keep the change.

I've never heard of any problems with mashing too long either. With that said I wouldn't try mashing for days at a time but 90 minutes is nothing to be worried about.
