    2 degree Celsius Mashing temperature less than usual affecting OG severely?

    Hi all, Yes I measured it roughly on my grainfather. It was slighlty lower than the 29 liters mark after whirlpool (70 degrees). So I guess something like 0.8 - 1 liters off my target. So the volume was a little bit more, but not enough to cause this big difference in OG. I have used Pale...

    2 degree Celsius Mashing temperature less than usual affecting OG severely?

    Hi, Yesterday, I wanted to try a Golden Ale, 28L batch size. I did mash in according to a recepie, at 64 - 65C for 70 minutes, and then sparged at about 78C, my OG ended up at 1.040 when the was supposed to be 1.052C (According to grainfather community calculator) I was pretty carefull...

    Fermentation profile IPA

    Could it be a touch of oxidation? I have experienced something similar before. I usually drink the beer after one day or so, cause they are so fresh and nice. But after two weeks, the hoppy flavours kind of disappeared and I also got this cidery kind of taste. It didn't turn brown as my...

    Limiting oxidation: effect of purging headspace O2 in a bottle conditioned IPA

    I guess most important is not to shake the bottle atleast, I have been brewing for just a year and it kinds of boggles met that on all this instruction, people claim to shake the bottle to mix the sugar solution. This has literally ruined 5 - 6 batches. I do put the caps in a no-rinse solution...

    Limiting oxidation: effect of purging headspace O2 in a bottle conditioned IPA

    Thank you all for good and interesting posts! One question, I see that you talk about purge and no purge, but do you flip the bottle upside down after capping it? I used to do that until some kind soul showed me a video about a guy doing an experiment and it proved to have a great deal of...

    Contamination or oxidation or maybe both?

    Nice! I will definitely try something like that, both convenient and seems quite cheap! Would definitely need it as well! Also I do both grain and extract brewing, I start with grain, about 4 kilos grain, then add an extra amount of extract to get up the percentage. khannon I actually do...

    Contamination or oxidation or maybe both?

    For my next brew tomorrow, I have a new fermentation bucket, which I will clean and sanitize like crazy. I will also use a new sanitizer, Sanipro rinse, which doesn't need rinsing. Then of course take your advice on more thoroughly bottle cleaning and sanitation, checking the bottling wand for...

    Contamination or oxidation or maybe both?

    By the way, the color change, first picture to the left is from fermentation (This was the bottom of the barrel), second is a couple of days after bottlign and the last is today. But not all bottles have this brown color, which is strange. .

    Contamination or oxidation or maybe both?

    I also heard that with the bottle cap, I will also try that for next time! Just hope it has the desired effect :) How long do you keep the beer and sugar solution before bottle it? What does the sodium meta bisulphate? I use both cleaner and sanitizer, and now I also have a new bucket for my...

    Contamination or oxidation or maybe both?

    Yes, I meant OG 1.046 :D I believe it's my poor english causing the misunderstanding. I have this arrangement. With the tube connected there to the bottom tap.

    Contamination or oxidation or maybe both?

    Thanks for your replies, I forgot to add a detail, some bottles are getting darker brown color than others. But the taste of hops are definitely gone in all of them that I have tried. Also, I brew 20 - 25 liter batches in a 30 liter fermentation bucket, with a siphon. I used Safale 04 and...

    Contamination or oxidation or maybe both?

    Hi, Regarding bottling wand, do you refer to the lid of the fermentation bucket? Yes, I don't need to remove it, but there is a hole for the water lock. I also dry hop, I did it a weak or so before I bottled the beer. Lastely, I add the sugar solution right into the bottles, before I add the beer.

    Contamination or oxidation or maybe both?

    Hi, I use a siphon tube (maybe bottling wand is the correct word) with a valve which opens when you tap it to the bottom of the bottle, so there is no splashing. I have the oxidation as my primary suspect, but can't really see how I can do it any better, besides the CO2 as you mentioned. There...

    Contamination or oxidation or maybe both?

    Dear all brewers! I have now been brewing beer for a little more than 6 months and I can’t really make it. A few times I had a similar aftertaste that I can’t really explain, but sometimes, it has been fine. Lately my beer had a nice orange color right after fermentation and in the bottle. I...
