My slightly unique BIAB method

I just finished brewing up a porter for my dad for father's day. It's my second beer brew ever and I wanted to share my small batch methods because... Well I just wanted to. Since I'm relatively new and short on funds I tend to favor small batches of anything. Before brewing I made a couple meads, and I have one cider in primary now, all of which are only gallon batches. So I decided after A LOT of lurking to try my hand at beer brewing since I've had some free time. For my gallon batches I scale back the grain bill to fit and I mash in an old water jug I used for lacrosse. I came up with this idea when I saw some pictures of people using coolers for homemade mash tuns. Instead of using a false bottom with a spigot I decided I would just use a bag (I thought I was quite clever, but came to find BIAB was already a thing haha). So I scaled back my grain bill, and mashed inside a water jug. To heat the strike water I don't even use a stove. I set an electric kettle to 160 and just use that. Every now and then I flip up the top on the jug that you are supposed drink out of and insert an electric meat thermometer to monitor temperature. My first batch was only a partial mash, but this recent porter was my second brew and I decided to go all grain. I know I should probably get some more experience before I start all grain, but... I didn't.:rockin:
I was amazed by the remarkable efficiency from my ghetto rigged setup! My efficiency using this method was right at 70% which I'm quite proud of given the small scale, ghetto rigged, BIAB. Anyway, I just wanted to share my very cheap, decently efficient, small scale setup with you all. Maybe there's a lurker who is in the same position I was and will find this helpful. Anyone else have unique or weird methods, or brew on a really small scale?

Very nice. Nothing like engineering your gear and then it working like you wanted it to.

Yes agreed! BIAB can be very simple...often folks are trying to make it complicated....cheers!
