This instructable is for a 5 gallon batch (roughly 25 bottles). You can scale it up or down to whatever you plan on making. You’ll need 3 pounds of honey and roughly 6 ounces of raspberries per gallon. Honey is expensive. I have since made a Raspberry Wine, exactly like this, but with Dextrose (Corn Sugar) as the fermentable sugar instead of honey. It’s considerably cheaper. BUT, you can no longer call it a Mead. And there will be obvious texture/mouth-feel/flavor differences. But they are both delicious. If you do end up going the sugar route, you don’t need 3 pounds/gallon, closer to 2 pounds/gallon. Use your hydrometer to fine tune, you’re aiming for about 1.10 or so as the starting gravity. I think I ended up needing about 12 pounds of dextrose. Anyway, on to what you’ll need. I’m assuming you’ve brewed before and already have basic brewing equipment. If not, take a look at my other Instructables, or any of the other ones on this site to see what you need.
