Hi,

I'm seeking advice on my one-gallon batch of mead, which was pitched 7 days ago, using 900g (2 lbs) of acacia honey and 1 gram of QA23 yeast. Having an OG of 1099, it now sits at 1092 after showing little signs of fermentation. By that I mean it has been visibly bubbling to some degree (like a bottle of Coke), with some activity in the airlock, but with little to no foam forming on the mead's surface. I've worked cleanly, and it doesn't smell foul, so I don't think my batch has been infected.

The temperature of the room it's located in is stable, around 21°C or 69-70°F.

Since Fermaid-O or K isn't readily available in my country and since this is my first batch, I've used boiled bread yeast as a substitute. Following a staggered nutrient schedule, I added 1 g BBY at pitch, another gram the day after and the third gram the day after that.

During the first couple of days, I gently stirred the carboy to introduce oxygen, but didn't pay much attention to oxygenating since my carboy has quite a lot of headspace (it's filled ⅘, 3L) and because I'd open the carboy daily for the first three days, to add the boiled yeast. As the fermentation isn't rigorous, I didn't notice much gas escaping in the first place.

Should I just be more patient? Or is this a sign my fermentation has stalled or something similar?
 
Well. You haven't given us much info. How long has it been since pitch> Did you pitchg your yeast slurry at the same temp your must was? Are sitting on top of your must in a carboy doesn't rweally add much at all for the yeast prior to going anerobic. It need to be induced into the must, by shaking or stirring wwith a whip/blender of some sort. I use bottled O2 and a centered stone. That does the bst. But you may not want to pay to get started off that way. If you do buy a bottle and a regulator. That is a great start to have a base to start out with. After that there are still a few more bottles of gasges you can use to really make much better mead.

I have made mead for a long time and it never contacts any O2 from the day I stop aerating until the day I bottle it. Even if I want to dry hop. You can even get that done without exposure to O2. One of the biggest helps anyone could ever do as a mead maker or wine. Is to buy O2 to aerate. And a bottle of Nitrogen to sparge the O2 out of suspension after fermentation is over. And them I always push my meads from one Korny keg to another by driving it wuith Nitorgen. I don't even carb anymore with CO2.

Of course none of this will help initially as well as listening to the podcast that start somewhere around 9/5/17
