<p>Are you back brewing now Richie? I did the Mike's Taranaki IPA recipe on fathers day yesterday, hoping for good things.</p>

<p>Hi All,</p>
<p></p>
<p>Thanks for your responses and ideas.</p>
<p></p>
<p>In the end I emptied out my entire garage, cleaned every surface, put on a haz suit sprayed the entire place with a strong bleach solution, biffed all equip used after the boil, bought new fermenters, hoses etc and problem solved.</p>
<p></p>
<p>Still don't know what it was but would have to hazard a guess at a wild and very virulent yeast.</p>
<p></p>

<p>not knowing what your process is for fermentation all that much and saying the flavor tends to condition out, i'd say give it an extra week at the elevated temperature. this might help eliminate any possible fermentation issues.</p>
<p>i'd also suggest resting at the higher temp a day earlier just to be sure. that'll remove the majority of any possibility of the big D as well</p>

<p>but a new bucket would be a safe bet (the SS brew bucket might be a good plan?)</p>

<p>Hi Dave,</p>
<p></p>
<p>I get the off flavour out of the fermentor. Over time in the keg it seems to dissipate, but is still there. I'm thinking a wild hard to kill yeast is in the environment and now in fermentors. Did try a new fermentor at one stage and I think that I had a good beer out of it (didn't write in my brew notes which fermentor I used). Regardless I getting bad beers out of that one now too...</p>

Hi Rich, two questions - are you kegging? And what does it taste like when you transfer from the fermentor?<br />
<br />
I had an issue like yours where I was getting diacetyl real bad every few brews, after many successful brews. Spent ages on fermentation etc before I finally tracked it to one of my kegs. I found there was a weld repair on one of the internal seams which must have been holding the bugs - even with severe cleaning and sanitation (I wrecked one last brew to prove my theory....) that keg…

<p>oh and i'd also suggest trying to actually identify the flavor your getting. a bitter aftertaste is quite broad.</p>
<p></p>
<p>taste your beers and describe what your tasting</p>
<p>plastic - metal/blood - tart/sour - astringent (overly dry) - green apples - butter - oversweetness - yeast bite - grainy - salty</p>

<p>Bitter aftertaste? </p>
<p></p>
<p>If your sure its not the D, then I'd say you've got an ongoing infection somewhere in your system. ball valves counter flow chillers etc.</p>
<p></p>
<p>alternatively, i was gonig to say see about your hops etc, but if your coopers lager is the same then i cant say that.</p>

<p>when i say strip i mean remove the valve and strip the valve where you can, things like that, replace and change seals.</p>
<p></p>
<p>i assumeyour kegging, so it could be in your keg as well change your selasn and strip it, checking for particles in your tubes and lines. (replaceyour beer lines as well)</p>
<p></p>
<p>i also notice you're in a plastic bucket.</p>
<p>I'd suggest replacing it. get a SS one or a carboy maybe? its possible you've got a minimal scratch, which is holding some form of bacteria.</p> Hi Rob,

<p>Your femrentation fridge, what is your heating source? and where is it in relation to the fermenter?</p>
<p></p>
<p>For your ferments try pitching at a lower temp and set your thermo to 19, then rise at 3 days to 21-22 </p>
<p>Pitching high and letting it fall to the recommended temp, can cause diacetyl, which can also casue overlasting long bitterness. </p>

<p></p>
<p>Try this.</p>
<p>1- pitch at lower than your set ferm temp</p>
<p>2- set your temp to around 19 degrees, and let it sit for max 3 days, then raise to 21-22, and let it sit for the remainder of the fermentation.</p>
<p>3- dryhop at your specified time, makingsure your hops are fresh, and kept cold before using. then cold crash for 48 hours keg, fine(if thats what you do), carbonate and enjoy.</p>
<p></p>
<p>Basically your diacetyl pre-cursors are too high, and your missing the D-Rest to help minimise it.</p>
<p>so pitch low, let it rise, do your d-rest early and keep it high, for the total ferment</p>
