In a large bowl add all the dry ingredients. The spelt flour, mixed seeds and salt. Break the fresh yeast into pieces and combine into the flour as good as possible.
Make a well in the center and add the honey, pour in the vinegar and water.
Mix and beat the ingredients into a dough with the help of your kitchen machine or by hand (that's a workout).
Preheat your oven to 390° Fahrenheit/200° Celsius.
Keep your baking pan ready by buttering it. Sprinkle some oats into the pan, that way you will have oats sitting on top of your bread which looks nice.
Pour your dough into the baking pan and smoothen out.
Bake your bread in the oven at 390° Fahrenheit/200° Celsius.
Take the bread out after 20 minutes and make a cut lengthwise into the bread on top. That way the bread won't deform during the baking process.
Place the bread back into the oven to and bake another 40 minutes. The total baking time is 60 minutes.

Notes
You can use mixed seeds such as pumpkin seed, sunflower seed, sesame seeds, flax seeds, chia seeds as well as oats. I used mainly sunflower and pumpkin seeds and the rest a mixed of chia, flax, sesame and oats.
I use white wine vinegar.
For the yeast, you can use fresh yeast or dry instant yeast. If you want to use dry instant yeast, use about ½ ounce (14 grams) dry yeast. I use fresh yeast because I prefer the taste, but this is my point of view, you might prefer regular dry yeast.
