Is there a right way to burp your fermentation jars?

I've been making hot sauce for about six months and always just cracked the lid a little to burp my jars. Then last week I saw a guy at a meetup in Denver carefully press down on the lid while burping to prevent oxygen from getting in. That got me thinking - does that tiny bit of oxygen actually ruin the batch, or is that overthinking it? I've never had a mold issue but now I'm paranoid. What do you all do when you burp your ferments?

Jumped in with the same worry when I started fermenting peppers last year, so I get it. I do the press-down method you saw, but honestly I think it's more about habit than science (if you're burping daily, that little air exchange probably doesn't matter). What really helped me was switching to airlock lids for my hot sauce ferments - I got a set off Amazon for like 15 bucks and now I never worry about mold or forgetting to burp. I keep one jar with a regular lid just for comparison, and I've had zero issues with either method as long as I'm careful about keeping everything below the brine. Your gut feeling about not overthinking it is probably right, but if you're prone to paranoia like me, those airlock lids are a game changer.

Two years ago I had a batch of habanero garlic go bad on me and I still don't know what caused it. I was doing everything right, keeping stuff under the brine, burping daily, all that. So I get why people swear by airlock lids for peace of mind. But I actually think burping is more important than most people give it credit for, because that pressure release helps keep bad bacteria from getting comfortable in the first place. I don't use any special lids, just a regular jar with a finger tight cap, and I burp it twice a day for the first week. Never had mold since that one bad batch. Maybe I just got lucky or maybe it's something else, but I see the burping as part of the whole fermentation dance, not just a habit.
