Excellent ! I too have a little bit of experience with grape and beer. Nice line in mixed metaphors - never peeled a cat before !

For a VH+ it put up a good fight against the one step. I found a chain

Code:

+--------------+---------------+--------------+
| 14  13  5    | 34  8    2    | 7   9   6    |
| 9   38  2    | 6   1347 157  | 34  15  58   |
| 48  7   6    | 345 134  9    | 34  125 258  |
+--------------+---------------+--------------+
| 3   6   7    | 2   9    4    | 5   8   1    |
| 5   4   9    | 38  13   18   | 2   6   7    |
| 18  2   18   | 7   5    6    | 9   4   3    |
+--------------+---------------+--------------+
| 2   58  48   | 1   47   57   | 6   3   9    |
| 7   15  14   | 9   6    3    | 8   25  245  |
| 6   9   3    | 458 2    58   | 1   7   45   |
+--------------+---------------+--------------+


(1=8)r6c1-(8=1)r6c3-(1=4)r8c3-(4)r7c3=(4-7)r7c5=(7-5)r7c6=(15-7)r2c68-(5=8)r2c9-(8=3)r2c2-(3=1)r1c2-(1)r1c1 (Lordy!)

So obviously if you set r6c1 to 1 then r1c1 < > 1 and puzzle solved

However, if you set r6c1 to 8 and follow the above chain then r1c1 is still < > 1 and puzzle solved.

Of course setting r6c1 to 8 and stay in column 1 and r1c1 =1. Contradiction so r6c1 < > 8.

If I extend the original chain by a final step

(1=8)r6c1-(8=1)r6c3-(1=4)r8c3-(4)r7c3=(4-7)r7c5=(7-5)r7c6=(15-7)r2c68-(5=8)r2c9-(8=3)r2c2-(3=1)r1c2-(1)r1c1=(1-8)r6c1

We have gone full circle to show that when you stick 8 in r6c1 the loop removes it so r6c1 < > 8 and puzzle solved (again)
