How do you know if your beer is infected?

I have a pineapple wheat beer on with six days now and it has stopped bubbling. Took sample today and it had gone from 1.058 down to 1.012 i think, anyway it worked out at 6.5% abv. Used a yeast starter and everything seemed to be going fine during ferment no off smells or anything, in fact the smells coming out of the airlock a few days ago were lovely. anyway i took a taste of the sample and it nearly curled my eybrows with bitterness. It smells sour as well, asked hoppybrewer on jtv and he said defo infected.

I wanted you guys opinion as its only my second brew and the first one went haywire because of temp problems(long story). If i have to chuck this one i will be gutted as i was so looking forward to it. My question is how can i be sure if it is infected and is there any point in bottling it as its due bottling over next few days? Thanks.

I have never used pineapple in beer, but saying its is 'defo infected' maybe wrong. Did you use real pineapple or something else to get the flavour? Most of the wheat beers I have tried have fairly light in colour, flavour etc.. there is a fair bit of alcohol in there and depending on how much pineapple you added tastes are going to show through strongly. Bitterness will drop over time. I wouldnt bottle anything till its been fermenting at least ten days anyway. If it is infected the 'off' flavours will probably get much worse. I'd leave it for a few more days and taste again.

to me that seems like a lot of pineapple... I have sent one of the other brewers here a message about this post, he will know more about wheat beers than I do, hopefully he will answer you soon.

I asked Jerid form Heavy Riff Brewing, his brewery opens in a couple of weeks!! He said to maybe secondary it and just continue testing and see how it goes. He also said when he adds the pineapple to his brews he makes sure he gets them in cans where its just pineapple chunks in water or natural juice, not the sweetened juice, and that he doesnt boil them because if it comes straight from the can then its sanitary. So he basically said the same, give it some time. He said you may have got some sour off flavours from the boiling but thats just a guess. Does the wort have any weird kind of layer on top or just look kind of normal, I suppose its hard cause you havent brewed many beers though to tell what is normal.

IPA will probably turn out better than the Lager can, the lager cans need a lot of love and nice cool and long brewing conditions to work well, I sometimes use the Lager cans when thats all I can get but I usually hop them up and add crystal and chocolate malt to totally change them.

No scum on top just looks normal,I used chunks from a can too so I should be ok there? The wort is amber colour. During ferment it had normal krizen on top and smelled grand coming out of bubbler, I only boiled the tins cause I thought it was more sanitary. Could that have screwed it up? Will stick it in secondary for another week and see what its like then but I have my doubts. Thanks m8 and thank jerid for me. Think I will keep it really simple for a while.

Hey Gash, got a quick question, was thinking about putting 2 All INN citra wort kits in the fermentersaurus, 30L, Then after ferment, adding the 5L cooled boiled water with priming Dex to each keg and filling, What do you think?
