    H2S in my hydromels, what am I doing wrong??

    You're right, sulfites aren't the end all be all, but none at all? I suppose gram negative is what I was afraid of. Environmental bacteria might rarely infect people, but the compounds they make especially from sugar carbon sources can be pretty nasty. Butyric acid 🤮🤮🤮

    H2S in my hydromels, what am I doing wrong??

    I'm gonna go reply to both those comments in one go. Trust a microbiologist here when I say potassium or sodium makes no difference when the concentration is so incredibly low and yes, there are viable dormant bacteria on those flowers. They don't need anything to feed on at the moment. Without...

    H2S in my hydromels, what am I doing wrong??

    I don't actually use tablets, I have a bag of metabisulphite but metabisulphite is the only component of Campden tablets, they are the same just a different name. I add it to sanitise the dried flowers, I buy them from a tea shop and I really want to make sure even the spore-forming bacteria are...

    H2S in my hydromels, what am I doing wrong??

    Is 36 hours not enough to get the excess sulfites out?

    H2S in my hydromels, what am I doing wrong??

    The temp range of CY17 is 16-24C and my house was at a pretty steady 20C while fermenting. Thanks for the tip on sulfites though..

    H2S in my hydromels, what am I doing wrong??

    I use MJ's yeast almost exclusively and I have never had issues with funky flavours using them for mead. I have tried M05 now for the first time but it is not done fermenting. The reason I picked CY17 actually, is because MJ recommend it for elderflower wine, so just changing the sugar source to...

    H2S in my hydromels, what am I doing wrong??

    Hi everyone, This is the second time I have tried to make a flower tea hydromel that resulted in sulfur smell and I really can't see what is so different about my recipe than what is shown on the internet. The first time I used less nutrients and staggered them, I read that I should add more...

    No, freezing does not kill bacteria

    Over the years I have seen so many people come and go, saying that freezing fruit is a way to sanitise it. Believe a mircobiologist here, when I say this is not true in the slightest. Look at the article Walker 2006 Freeze-Thaw Tolerance and Clues to the Winter Survival of a Soil Community...

    Scotch Oaked Mead

    Also, the packaging has 10 gram cubes, but the dosing says 5-30 grams per 10 liters. In 5 liters, should I only use one cube?

    Scotch Oaked Mead

    Hi all, Soon I want to make a 17% (Sack?) mead. I have these scotch whisky oak blocks to condition with. However, I'm wondering what else to do with this mead. Just wood seems a bit bland. Have you guys got any experience with oaking mead with infused oak? What would you add to a high ABV...

    Brewferm autosiphon "Flow'in" with bottling wand impossible to remove?

    That is a really good idea, I didn't know these taps existed, thank you so much!

    Brewferm autosiphon "Flow'in" with bottling wand impossible to remove?

    Well I already had to cut the wand off to use it for standard racking, so I doubt they will take it back.. I was hoping someone dealt with re-attaching it before

    Brewferm autosiphon "Flow'in" with bottling wand impossible to remove?

    Hello all, Today I racked some mead with the siphon mentioned above. One problem though, it comes with a bottling wand pre-attached? I tried everything to get the wand off, hot water, heat-gun etc. but it wouldn't budge. I had already started the racking process and had to follow through, so I...

    To squeeze or not to squeeze

    What tool do you use, that you know so exactly what amount of pressure you are squeezing at?

    To squeeze or not to squeeze

    Interesting method, are you not afraid of oxygenation when returning the pressed juice to the fermenter?

    To squeeze or not to squeeze

    Hello, Currently I have a cherry and berry mead in my fermenter with whole squeezed fruit. Naturally I am hoping to get the most volume I can out of this. Once the fermentation has ended I want to rack, but I was wondering, do any of you who don't use bags squeeze this fruit to get some more...

    Concerned about volume berries take up in a fermenter

    Hi, I am interested in making a berry recipe, but some recipes state to add almost 3 kg's to 5L??? For reference, 3 kg of berries take up 4.8L of volume according to this calculator: https://www.aqua-calc.com/calculate/food-weight-to-volume How do you guys make a 5L batch with 3 kg's of...

    What do brewers mean by attenuation and how does alcohol tolerance come into play?

    "Honey will be fermented completely because it is almost entirely fructose and glucose". I hear so many brewers say this but from my personal scouring of the internet I seem to find that isn't entirely correct. In Lane et al. 2019 it is stated that 25% of the sugars in honey are...

    Ending acidity of mead?

    Hi, Everyone seems to be talking about the pH during fermentation, but what pH should mead be in the bottle? I am thinking about making a lemon themed recipe at some point and I would love to hear if anyone has experience with a little more acidic tasting meads.

    What do brewers mean by attenuation and how does alcohol tolerance come into play?

    Honestly, thinking about it a little bit more there are so many factors (especially the percentage of non-fermentable sugars in honey). And you're right, what's the use testing these things if you are going to neglect other factors? I feel like malt is the same as honey in the non-fermentable...
