I have been brewing extract kits for about a year and a half now, for the longest time I used dextrose only and have recently started spending the little extra to switch to DME. I want to switch to all grain when I eventually get my own place and have more room to work on it. IMO I think the biggest difference between kits and all grain is the ability to have more control over flavor profiles, IBU's which is the main reason I will want to change down the road.
Cheers and happy drinking!
I got my first homebrew starter kit back around 2000 and have been an extract brewer since. I was in college so I didnt have extra money to buy, or room to store, upgrades or accessories. As a young adult, i would brew up to a couple times a year, depending on the hectic schedule of life/kids/work/ect. I had heard of all grain brewing in the books, but because i brewed so infrequently, and only had the basic gear, i rarely have it much though. And the electric stove/lack of fryer.
A couple years ago, i gave up my one weekend a month, two weeks in the summer job, so i had more time to spend on my hobbies. Now I was brewing more, but all grain required more eqpt that i didnt have, and was hesitant to buy. I kept brewing, but needed upgrades. Slowly started upgrading. Now for my extract brewing, i have a dark star burner, wort chiller, extra buckets, extra carboys.
But still an extract brewer, and i am still happy with the results.
You do realize that you can brew all grain with the equipment you have now don't you?? All you need is to get a bag to hold the grain. If you are using a 5 gallon pot you can use a paint strainer bag that you can get almost anywhere they sell paint.....
