How can i get diacytyl???

[cgravier]

i just started drinking a boston ale clone i made which came out awesome except when compared to the real thing, i can definetly taste diacytyl in the original, and i was wondering how you get this so-called 'undesirable' flavor. i tried fermenting on the cold side(64f), but the beer is clean as a whistle...im using east coast ale yeast.

I thought diacytyl could come from boiling with the lid on your brewpot?

i know that lagers require a diacytl rest, which brings the temp up enough for the yeast to scrub off any diacetyl, but i dont know how it works for ale yeasts. (im assuming lagers produce alot during there cold fermentation)

diacetyl is a byproduct of the yeast during fermentation, ale or lager yeast, (or a bacteria infection!). a weak ferment w/ a long lag can produce extra diacetyl or lack of oxygenation/aeration of the wort prior to pitching can cause it. what happens is there is too much diacetyl for the yeast to consume at the end of fermentation, so it stays behind in larger amounts in the finished brew.

Many yeasts will produce diacytyl when they are struggling. Kind of depends on the yeast strain. Yours is probably very clean and will probably not generally produce it. I would try the fermentation at higher temps (like 74 to 76) and see how that goes. You might want to check with around to see what yeasts produce it at what temps.

I just made this beer. Its in my primary's now. I did catch the news before hand and fermented at 74 Deg F. I used the same East Coast ale yeast and was told to ferment at higher temps..72 -76 deg F. We'll see. This is the first try at this clone. It was an "All-Grain" but I had to sacrifice 2-row with Maris Otter. mainly because my HBS was out of everything. It won't be a true comparison but at least its a road less traveled.

I used WL Irish Ale yeast for my stout.

The WL website says it produces a slight diactyl and fruity taste. I can definitely taste the fruitiness. Not too sure what diactyl tastes like. This yeast did anything but struggle. It went like gangbusters from the get-go....

Nope, that is DMS.

DMS is a cooked corn smell/taste, diacetyl is buttery.

if you can pick up a couple of bottles of fuller's esb or london pride, the only thing you will tase is diacetyl...

I'll second cowain's suggestion....ferment at a higher temp, say around 68-69F.

Can't say I've ever picked up on diacetyl in Boston Ale.

Ahhh, thanks... I had heard it tastes like butterscotch. The Dude says it tastes buttery. I'll keep an eye out for the brands you mentioned.

Only if it's stale. If they are fresh, then the hops overpower the diacetyl.
